GRE sentence equivalences two strategies

One of the things that often gets overlooked in discussions about standardized testing is that scoring well is often a matter of having strategies, plural, rather than a single strategy. Different items may call for different approaches, even when they are the same type of question, and nowhere is this fact illustrated more clearly than on GRE sentence equivalences. In some cases, you may be able to identify the answer almost instantaneously using a shortcut approach, whereas in other cases you may need to work through the sentence very carefully, circling key words, playing positive/negative, and dodging trick answers left and right. The key is to know which strategy to use when. With that said, lets look at two ways that sentence equivalences can be approached. 1) Use the answers to work backward Although correct answers to sentence equivalences do not need to be exact synonyms, in many cases they will have very similar meanings. One way to narrow down potential answer choices is therefore to start by scanning the answer choices for such words. For example, consider the following set of answers: [A]   multiply [B]   abate [C]   merge [D]   relapse [E]   subside [F]   linger This isnt the hardest set of answer choices, but it isnt the easiest one either. None of the words is particularly obscure, and only abate would show up on most traditional GRE vocabulary list. The answers are, however, all similar enough to give a lot of test-takers pause. If you really know your vocabulary and can keep your head on straight, though, there are actually only two words here that are truly likely to create the same meaning when plugged into a sentence. In fact, theyre straightforward synonyms: abate and subside. What further suggests that this pair is correct is that it follows a classic sentence equivalence answer choice pattern: one easy word (subside) and one GRE word (abate) that test-takers are less likely to know. To be clear, though: you should never never choose a set of answers without going back and plugging them into the sentence to make sure they actually fit. The point of this strategy is only to help you identify the most likely answers faster; you still need to check to make sure they make sense in context. So now, were going to look at the actual sentence. Some commonly prescribed medications can initially provoke side-effects ranging from anxiety to weight-gain, but these symptoms typically ____________ within weeks as patients bodies adjust. The contradictor but indicates that the two halves of the sentence will have opposite meanings. The first half of the sentence indicates that some common medications cause side effect, so logically, the second half of the sentence must indicate that these side effects eventually go away or decrease an interpretation supported by the phrase as patients bodies adjust. Given that context, abate and subside make perfect sense. However, if the correct answers have meanings that are too dissimilar, or if there are multiple synonym pairs, this strategy will be of limited use. For example, the above set of answers could also be written this way: [A]   remain [B]   abate [C]   merge [D]   relapse [E]   subside [F]   linger Here, there are two potential sets of words: remain/linger and abate/subside. You can be reasonably certain the other answers are incorrect, but without actually looking at the sentence, there is no way to know which pair is correct. That is also why you should never jump to pick the first set of synonyms you notice there might be another pair of synonyms, or relatively similar words, that are a much better fit for the sentence. If there isnt an obvious set of synonyms, or if you simply find working from the answers too confusing, then you can always 2) Work from the sentence to the answers This should probably go without saying, but just in case, Ill reiterate it here: in order to work most effectively, you must do some basic legwork upfront, before you check the answers. If you dont have a clear idea of what sort of words youre looking for, youre likely to get confused or second-guess yourself. The major pitfall of this approach is that you can end up focusing so hard on finding words that fit that you neglect to fully consider whether they create the same meaning. For example: Amy Tans memoir Where the Past Begins is not a conventional narrative autobiography; rather, it is a series of ____________ chapters that resemble a collage or a scrapbook more than a standard chronological excavation of the past. The sentence sets up an opposition between Tans memoir and conventional narrative autobiography, indicating that the memoir does not consist of a conventional narrative. In addition, the phrase standard chronological excavation indicates that the narrative does not discuss the events of Tans life in order. The correct answers must therefore be consistent with the idea of lacking order. Now, take a look at the answers: [A]   linear [B]   rambling [C]   unintelligible [D]   fragmented [E]   lyrical [F]   disjointed Linear is the exact opposite of the required word, so [A] can be eliminated right away. Rambling means long-winded or wordy. This type of narrative could plausibly be considered the opposite of a conventional point-A-to-point-B narrative, so [B] fits. Unintelligible has the right idea, but its too strong: its unlikely that an authors memoir, no matter of unconventional, would be downright incomprehensible. Its a pretty safe bet that [C] is wrong too. [D], fragmented fits: a narrative that didnt move in linear or chronological fashion could be described this way. Lyrical (poetic) isnt the most obvious match for the clues in the sentence, but it still works: a lyrical memoir would not be a standard chronological one. So [E] stays. Disjointed is also consistent with the idea of a narrative that jumps around in time, so [F] stays as well. So that leaves us with four possible answers: [B]   rambling [D]   fragmented [E]   lyrical [F]   disjointed The question now shifts from which words make sense in context to which words produce the same meaning? Lyrical is the outlier here, so [E] can be eliminated. This is where you need to be very careful: rambling, fragmented, and disjointed   are all similar but a rambling narrative is one that is merely lengthy and tends to go off on tangents, whereas a fragmented or disjointed narrative is by definition one that presents events in random order, that leaps back and forth in time in a choppy, illogical way. The difference is subtle, but its there. [D] and [F] are exact matches for the clues in the sentence AND produce the same meaning when plugged in, so they are correct.

Does Developmental Generativity Predict Substance Use...

Does Developmental Generativity Predict Substance Use in Middle Aged Adults? Erikson’s (1968, 1980, 1982) psychosocial stages of development provide a framework for the different stages of development throughout the human lifespan. These stages of development begin at birth and continue until death, and separate the lifespan into eight stages based on chronological age. Within these eight different aging stages are corresponding psychosocial stages. Each of these psychosocial stages represent a conflict between two characteristics of development for that particular time period in a person’s life. The beginning stages of Erikson’s (1968, 1980, 1982) model focus almost entirely on the individual and the self, developing those personal characteristics and developing the idea of the self. It is not until middle adulthood that the psychosocial conflict changes perspective to reflect outside of the self. The seventh psychosocial stage is generativity versus stagnation, which takes place during the ages of 40 to 60. In this stage, the in dividual turns the focus outside of themselves and starts to focus on society, community, and the family. While a person can feel generative by having their own family and children, this is only a small part of being successfully generative. Generativity can roughly be described as connection between generations. This entails having a desire to contribute to the next generations, as well as creating and accomplishing things

Antimicrobial Activity of Soil- Research Proposal free essay sample

Microbes produce various antibiotics and by isolating different microbes the antibodies can be tested for. Soil samples are highly rich in microorganisms. The antimicrobial  activities of microbes from 3 different soil sources (Tenby, Summerstrand, North Campus main building round-about and South Campus water pond) will be tested. Pure colonies isolated from the microbes will be tested for antimicrobial activity against known microorganisms of medical importance; these being E. coli, staphylococcus aureus, Shigella dysenteriae, Shigella sonnei and salmonella spp. Isolates of soil microbes can be categorized and  characterized based on a number of criteria ranging from gram-staining which will be done in this project, for enumeration which is a quantitative description based on the amount of microbial colonies available. The results will be recorded. Key words: soil, microbes, microbial activity, antimicrobial resistance INTRODUCTION It is vital for science today to focus on the isolation and characterisation of an unknown organism expressing interesting properties in relation to antimicrobial Activity. At the conclusion of this laboratory experience the researcher would be required to describe the isolates obtained from the soil macroscopic and microscopic appearance, perform the gram stain of the microorganisms in question and to discriminate the organisms from other microbes that could be contained in the soil and to finally make certain that the organisms have not been exposed to outside sources and be isolated in a pure culture. The researcher must first isolate the microbe then, grow the organism in a pure culture. Pure colonies will be tested for antimicrobial activity against known microorganisms of medical importance. The evaluation of the results that will be achieved are important in the understanding the development of new antimicrobial drugs. LITERATURE REVIEW Soils typically contain 109  to 1010  microorganisms per gram (dry weight), which may represent more than a million bacterial species. However, characterization of the small fraction of microbes that has been cultivated provides only a glimpse of their potential physiological capacity and influence on soil ecosystems. The absence of pure cultures or genome sequences makes it difficult to ascertain the roles of specific microbes in soil environments. Eichorst, Breznak and Schmidt (2007) Diarrhoea caused by Shigella species is estimated by WHO to cause 50% of dysentery cases. S. dysenteriae serotype 1 is particularly virulent, causing endemic and epidemic dysentery with high death rate. Salmonella organisms are endemic in many tropical and developing countries, while other salmonellas cause food poisoning and bacteraemia. It is highly infectious and resistance to common available antimicrobials is an increasing problem. Cheesbrough (2000, p. 97) Antimicrobial resistance is resistance of a microorganism to an antimicrobial medicine to which it was previously sensitive is on the rise. Resistant organisms such as bacteria are able to withstand attack by antimicrobial medicines, such as antibiotics. Infections caused by resistant microorganisms often fail to respond to conventional treatment, resulting in prolonged illness and greater risk of death. World Health Organisation (2012) discusses the problem of antimicrobial resistance Synthesis of medicinally important compounds is very difficult and thus the cost of medicine is also high because of the non availability of source materials especially aromatic compounds Gopalakrishnan (2011) AIM OF RESEARCH The main aim of this research is to determine whether or not soil bound microbes’ exhibit antibiotic activity against known bacteria of medical importance. OBJECTIVES OF STUDY * To develop a new antimicrobial agent. * To reduce the ever expanding problem of antimicrobial resistance in treatment of bacterial infections. RESEARCH METHODOLOGY * METHOD(S) TO FASCILITATE MICROBIAL IDENTIFICATION Gram stain * Gram stain will be used to identify the gram bacterial membrane reaction for easy identification. Culturing * Nutrient agar will be used for the culturing of the soil supernatant to favour growth of most bacteria.

(2009) Cheesbrough (2000) lists the different microbiological requirements the facilitate the budgeting of a research Higdon and Topp (2004) give some guidelines on how to prepare a research proposal budget CONCLUSION The search for anti-secretory drugs continues, with real progress having been made. Soil and plants are the potential source of many drugs; but they did not yet get proper recognition. The role of antimicrobial agents in the management of infective bacterial conditions continues to be clarified with the emergence of new agents and simplified treatment regimens. Probiotics are popular with diarrhoea sufferers and have been shown to have some efficacy. However, further scrutiny is required to determine the magnitude of their effects and continued research on new development of anti diarrhoea agents in needed. Antibiotic resistance is a major clinical problem in treating infections caused by these microorganisms. One way to prevent antibiotic resistance of the pathogenic species is by using new compounds that are not based on existing synthetic antimicrobial agents. It is then vital to do more research on soil antimicrobial activity. Chanu, Chakraborty el tol (2011)

Prostitution Essays (527 words) - Prostitution, Sex Industry

Prostitution I. Introduction Prostitution, performance of sexual acts solely for the purpose of material gain. Persons prostitute themselves when they grant sexual favors to others in exchange for money, gifts, or other payment and in so doing use their bodies as commodities. In legal terms, the word prostitute refers only to those who engage overtly in such sexual-economic transactions, usually for a specified sum of money. Prostitutes may be of either sex, but throughout history the majority have been women, who have usually entered prostitution through coercion or under economic stress. II. Preindustrial Societies Prostitution was widespread in preindustrial societies. In the ancient Middle East and India, sexual intercourse with prostitutes was believed to facilitate communion with the gods. In ancient Greece, prostitution flourished on all levels of society. In ancient Rome, prostitution also was common, despite severe legal restrictions. In the Middle Ages (5th century to 15th century), the Christian church, which valued chastity, attempted to convert or rehabilitate individual prostitutes but did not attack the institution itself. By the late Middle Ages, licensed brothels flourished throughout Europe, yielding enormous revenues to government officials and corrupt clergy members. During the 16th century prostitution declined sharply in Europe, largely as a result of stern reprisals by Protestants and Roman Catholics. They condemned its immorality but were also motivated by a connection between prostitution and an outbreak of syphilis, a disease that is often transmitted through sexual contact. III. Industrial Societies In the 18th century most continental European governments controlled prostitution through a system of compulsory registration, licensed brothels, and medical inspection of prostitutes. In Britain and the United States, prostitution flourished openly in urban so-called red-light districts. In time the corruption of licensed prostitution stirred protests throughout Europe. Many governments sought to check prostitution by trying to stop the international traffic in women and children. IV. Prostitution in the United States Prostitution in the United States today takes various forms. Some prostitutes, so-called call girls, operate out of their own apartments and maintain a list of regular customers. Some follow convention circuits or work in certain resort areas. The majority are so-called streetwalkers, who find their customers on city streets. Increasing numbers are young runaways to the city who turn to the streets for survival. Many prostitutes are managed by men known as pimps, who usually take much of the money earned by the women. V. Current U.S. Attitudes The United States remains one of the few countries with laws against prostitution. It is legal only in the state of Nevada. The rationale for its continued illegal status in the United States rests on three assumptions: prostitution is linked to organized crime, prostitution leads to increased crime in general, and prostitution is the cause of an increase in sexually transmitted diseases. These assumptions are now in question, as some experts have pointed out that prostitution is no longer an attractive investment for organized crime, and as public-health officials indicate that prostitutes account for only a small percentage of the country's sexually transmitted disease cases. Polls have shown that approximately half of the U.S. population would favor decriminalization of prostitution throughout the country. Decriminalization would free the courts and police to spend more time dealing with what are seen as more serious and violent crimes. The constitutionality of laws against prostitution is also in question, since they penalize prostitutes but not their customers.

To live or to die essays

To live or to die essays Everyday hundreds of Americans die in either accidents, shooting, from sickness, and evening the death penalty. Capital punishment is a very difficult issue and there are as many different opinions for or against it as there are people. Each yeah over two hundred people are placed on death row. Some of those people deserve to be on death row and a few dont but there is no way to separate the wrongly accused from those who belong. To live or to die is the question that crosses every judges mind when the time comes to prosecute a criminal. It is not an easy decision but it has to be made. Once the decision is made to place someone on death row, there is no turning back, only the anticipation of that day when a life is brought to an end slowly but surely. Those opposing capital punishment think of losing a loved one to someone who has no meaning for taking a life. those who are defending capital punishment, think about a loved one that maybe wrongly accused and sentenced to death. There are two sides to capital punishment either to live or There was a period were capital punishment was ruled unconstitutional by the supreme court. Their reason for this was that the death penalty was cruel and unusual punishment under the eighth amendment which states, that excessive bail shall not be required, nor excessive fines imposed, no cruel or unusual punishment inflicted. When the constitution was drafted, indeed capital punishment was practiced widely in this country but it was not specified as cruel and unusual. Those who are for capital punishment argue that penal laws are demonstrating to everyone that it is not in the best interest to murder. Capital punishment is something that is deserved when someone takes the life of another individual for no reason. The fear of death deters people from committing crimes, says Leslie Cantu (Interne ...
