median per day is wrong. However the median is 84.

from the q -- if k is 1. k-12 is odd then k can be any odd value. 2. Prime numbers can never be negative. but k-12 can be 2,3,5. So can be odd except 14. For all values it satisfy the Q step quation. Now combining as well k can be many posive odd value and one even value. For everything Q stem is valid. So E.

it should be E. Key is to take the numbers 0

total choices - 10X9X8 - 720 no women choice - 6X5X4 (6c1X5C1X4C1) = 120 so choices contains at least one women - 720 - 120 = 600

Any successive number set's median=mean. So its A.

1997 and 2 addition of 2 prime numbers are always even if one of them does not have 2. as the addition of 2 primes here is odd, so one must be 2. so other is 1997

Thanks gmatfundoo

A. x=10a+b and y=10b+a then x-y=9a-9b which is divisable by 9 B. x= 53, y=35 then x-y =18 which is divisable by 9 x= 64, y=35 then x-y =29 which is NOT divisable by 9 So ans is A.

I would say this is E. whats the OA?

yes it is C.

with C.

I'll go for B and D.

accenture -- it works with alzebra... sqare out both sides - (|x - y|)^2 > (|x| - |y|)^2 solving this - -2xy > -2|x| .|y| so, xy think when this can be true..only when one of the x or y be 0. so, xy B tells that xy>0 so ans is no. Hence B. HTH.

The formation of hurricanes that threaten the Unite States mainland is triggered by high atmospheric winds off the western coast Africa. When abundant rain falls in sub-Saharan Africa, hurricanes afterward hit the United States mainland with particular frequency. Therefore, the abundant rains must somehow promote the ability of the winds to form hurricanes. Which one of the following arguments contains a flaw that is most similar to one in the argument above? (A) People who exercise vigorously tend to sleep well. Therefore, people who exercise vigorously tend to be healthy. (B) Cars drive faster on long city blocks than on short city blocks. Long blocks are thus more dangerous for pedestrians than short blocks. © Many people who later become successful entrepreneurs played competitive sports in college. Therefore, playing competitive sports must enhance a person’s entrepreneur ability. (D) The blossoms of the chicory plant close up in full sun. Therefore the chicory plant’s blossoms must open up in the dark. (E) Events in Eastern Europe can affect the political mood in Central America. Therefore liberalization in Eastern Europe will lead to liberalization in Central America. OA is can anyone please explain?:hmm:

Yes OA is C. I think i got it now....I should have negated the options. :doh:

The 1980’s have been characterized as a period of selfish individualism that threatens the cohesion of society. But this characterization is true of any time. Throughout history all human actions have been motivated by selfishness. When the deeper implications are considered, even the simplest “unselfish” acts prove to be instances of selfish concern for the human species. Which one of the following is a flaw in the argument? (A) The claim that selfishness has been present throughout history is not actually relevant to the argument. (B) No statistical evidence is provided to show that humans act selfishly more often than act unselfishly. © The argument assumes that selfishness is unique to the present age. (D) The argument mentions only humans and does not consider the behavior of other species. (E) The argument relies on two different uses of the term selfish. OA . I can reach the answer by POE but not very conviced how to reach there directly?

Dr. Godfrey: Now that high school students are allowed to work more than 15 hours per week at part-time jobs, those who actually do so show less interest in school and get lower grades than those who do not work as many hours at part-time jobs. Obviously, working long hours at part-time jobs during the school year contributes to the academic problems that many of our high school students experience. Dr. Nash: That’s not so. Many of our high school students set out to earn as much money as they can simply to compensate for their lack of academic success. 16. The answer to which one of the following would be the most helpful in determining whether the conclusion that Dr. Godfrey draws could be logically defended against Dr. Nash’s counterargument? (A) whether people who have had academic problems in high school are ultimately less successful in their careers than people who have not had such problems (B) whether students are allowed to spend more than 15 hours per week at school-sponsored nonacademic extracurricular activities such as team sports or clubs © whether the students who work more than 15 hours per week and have academic problems had such problems before they began to work that many hours (D) whether employers and high school students typically obey all the laws that regulate the conditions under which young people may legally be employed (E) whether high school students who have after-school jobs continue to work at those jobs after graduating from high school CAn anyone please explain why A is not the answer? I believe we need to defend Dr. Godfrey's claim in light of Dr. Nash's counterargument.

Reptiles are air-breathing vertebrates with completely ossified skeletons; so alligators must be air-breathing vertebrates with completely ossified skeletons. In terms of its logical features, the argument above most resembles which one of the following? (A) Green plants take in carbon dioxide and release oxygen back into the air; so it follows that grass takes in carbon dioxide and releases oxygen into the air. (B) Some red butterflies are poisonous to birds that prey on them; so this particular red butterfly is poisonous to birds that prey on it. © Knowledge about the empirical world can be gained from books; so Virginia Woolf’s book A Room of One’s Own must provide knowledge about the empirical world. (D) Dierdre has seen every film directed by Rainer Werner Fassbinder; so Dierdre must have seen Ali: Fear Eats the Soul, a film directed by Fassbinder. (E) Skiers run a high risk of bone fracture; so it is likely that Lindsey, who has been an avid skier for many years, has suffered a broken bone at some point.

11. Unless they are used as strictly temporary measures, rent-control ordinances (municipal regulations placing limits on rent increases) have several negative effects for renters. One of these is that the controls will bring about a shortage of rental units. This disadvantage for renters occurs over the long run, but the advantage—smaller rent increases—occurs immediately. In many municipalities, specifically in all those where tenants of rent-control units have a secure hold on political power and can get rent-control ordinances enacted or repealed, it is invariably the desire for short-term gain that guides those tenants in the exercise of that power. If the statements above are true, which one of the following can be properly inferred from them? (A) It is impossible for landlords to raise rents when rent controls are in effect. (B) In many municipalities rent-control ordinances are repealed as soon as shortages of rental unites arise. © The only negative effect of tent control for renters is that it brings about a shortage of rental units. (D) In many municipalities there is now, or eventually will be, a shortage of rental units. (E) In the long term, a shortage of rental units will raise rents substantially.

Closest answers are A and E. B is too extreme for a regular assumption question. E says - "Heat generated by Sandactylus in flapping its wings in flight could not have been dispersed by anything other than the blood vessels in its wings. ". Negate this - "Heat generated by Sandactylus in flapping its wings in flight could have been dispersed by anything other than the blood vessels in its wings. " -- does this break - "Sandactylus flew by flapping its wings, not just by gliding"??? I think no. so A is the answer.

A physician who is too thorough in conducting a medical checkup is likely to subject the patient to the discomfort and expense of unnecessary tests. One who is not thorough enough is likely to miss some serious problem and therefore give the patient a false sense of security. It is difficult for physicians to judge exactly how thorough they should be. Therefore, it is generally unwise for patients to have medical checkups when they do not feel ill. Which one of the following, if true, would provide the most support for the conclusion in the passage? (A) Not all medical tests entail significant discomfort. (B) Sometimes unnecessary medical tests cause healthy people to become ill. © Some patients refuse to accept a physician’s assurance that the patient is healthy. (D) The more complete the series of tests performed in a medical checkup, the more likely it is that a rare disease, if present, will be discovered. (E) Physicians can eliminate the need to order certain tests by carefully questioning patients and rejecting some possibilities on that basis. Now sure how to eliminate E??? can anyone help?

excellent devp...i am clear now. Thanks. OA is A.

Many Native Americans view the archaeological excavation and museum display of ancestral skeletal remains and items buried with them as a spiritual desecration. A number of legal remedies that either prohibit or regulate such activities may be available to Native American communities, if they can establish standing (a position from which one may assert or enforce legal rights and duties) in such cases. In disinterment cases, courts have traditionally affirmed the standing of three classes of plaintiffs: the deceased’s heirs, the owner of the property on which the grave is located, and parties, including organizations or distant relatives of the deceased, that have a clear interest in the preservation of a particular grave. If an archaeologically discovered grave is of recent historical origin and associated with an identifiable Native American community, Native Americans are likely to establish standing in a suit to prevent disinterment of the remains, but in cases where the grave is ancient and located in an area where the community of Native Americans associated with the grave has not recently lived, they are less likely to be successful in this regard (in this regard: adv.在这点上). Indeed, in most cases involving ancient graves, to recognize that Native Americans have standing would represent a significant expansion of common law. In cases where standing can be achieved, however, common law (common law: 习惯法) may provide a basis for some Native American claims against archaeologists and museums. Property law, for example, can be useful in establishing Native American claims to artifacts that are retrieved in the excavation of ancient graves and can be considered the communal property of Native American tribes or communities. In Charrier v. Bell, a United States appellate (appellate: adj.受理上诉的) court ruled that the common law doctrine of abandonment, which allows the finder of abandoned property to claim ownership, does not apply to objects buried with the deceased. The court ruled that the practice of burying items with the body of the deceased “is not intended as a means of relinquishing ownership to a stranger” and that to interpret it as such “could render a grave subject to despoliation either immediately after interment or…after removal of the descendants of the deceased from the neighborhood of the cemetery.” This ruling suggests that artifacts excavated from Native American ancestral graves should be returned to representatives of tribal groups who can establish standing in such cases. More generally, United Sates courts have upheld the distinction between individual and communal property, holding that an individual Native American does not have title to communal property owned and held for common use by his or her tribe. As a result, museums cannot assume that they have valid title to cultural property merely because they purchased in good faith an item that was originally sold in good faith (in good faith:诚意地,老实地) by an individual member of a Native American community. ~~~~~~~~~ The passage suggests that in making the ruling in Charrier v. Bell the court is most likely to have considered the answer to which one of the following questions? (A) Are the descendants of the deceased still alive? (B) What was the reason for burying the objects in question? © How long after interment had buried objects been claimed by stranger? (D) Did the descendants of the deceased remain in the neighborhood of the cemetery? (E) Could the property on which buried objects were found be legally considered to be abandoned property? 14. Which one of the following best expresses the main idea of the passage? (A) Prior to an appellate court’s ruling in Charrier v. Bell, Native Americans had no legal grounds for demanding the return of artifacts excavated from ancient graves. (B) Property law offers the most promising remedies to Native Americans seeking to recover communally owned artifacts that were sold to museums without tribal authorization. © The older the grave, the more difficult it is for Native Americans to establish standing in cases concerning the disposition of archaeologically excavated ancestral remains. (D) In cases in which Native Americans can establish standing, common law can be useful in protecting ancestral remains and the artifacts buried with them. (E) Native Americans are unlikely to make significant progress in the recovery of cultural property until common law is significantly expanded to provide them with standing in cases involving the excavation of ancient graves.

Certain items—those with that hard-to-define quality called exclusivity—have the odd property, when they become available for sale, of selling rapidly even though they are extremely expensive. In fact, trying to sell such an item fast by asking too low a price is a serious error, since it calls into question the very thing—exclusivity—that is supposed to be the item’s chief appeal. Therefore, given that a price that will prove to be right is virtually impossible for the seller to gauge in advance, the seller should make sure that any error in the initial asking price is in the direction of setting the price too high. The argument recommends a certain pricing strategy on the grounds that (A) this strategy lacks a counterproductive feature of the rejected alternative (B) this strategy has all of advantages of the rejected alternative, but fewer of its disadvantages © experience has proven this strategy to be superior, even though the reasons for this superiority elude analysis (D) this strategy does not rely on prospective buyers estimates of value (E) the error associated with this strategy, unlike the error associated with the rejected alternative, is likely to go unnoticed

Much of the best scientific research of today shows that many of the results of earlier scientific work that was regarded in its time as good are in fact mistaken. Yet despite the fact that scientists are above all concerned to discover the truth, it is valuable for today’s scientists to study firsthand accounts of earlier scientific work. Which one of the following, if true, would best reconcile the two statements above? (A) Many firsthand accounts of earlier, flawed scientific work are not generally known to be mistaken. (B) Lessons in scientific methodology can be learned by seeing how earlier scientific work was carried out, sometimes especially when the results of that work are known to be incorrect. © Scientists can make valuable contributions to the scientific work of their time even if the results of their work will later be shown to be mistaken. (D) There are many scientists today who are not thoroughly familiar with earlier scientific research. (E) Some of the better scientific research of today does not directly address earlier scientific work. OA follows.
