This looks unofficial to me, too! To clarify, the last sentence about women's preferences is ambiguous. It could be read as "All else being equal, women prefer more feminine features on their men." In that case, other features in (A) are irrelevant, because we are assuming everything else is equal--I assume that's why the author's ruled out that choice. But the sentence could mean "Women primarily choose men with feminine features" or "out of 100 random men, women are most likely to pick the men with feminine features." And by that reading, (A) is a solid weakener: women prefer other things about men, and facial features are a tiebreaker at best!
(E), however, unambiguously wrecks the argument, whichever reading you take. The sample of the study was biased, and the feminine and masculine men were not representative of the general population of men. A study flaw undermines the credibility of the research, and thus on that research's conclusion.
E - is a weakener. Here, the sample under study is a suspect. In kaplan term its "representativeness" ( well, i am a kaplan course student), where the author believes the sample under study is apt for his conclusion.
But I am not sure, how A is weakener. The author is not arguing that the "facial feature" is the "only" basis of the preference. Author has just cited an evidence and derived a correlation. And correlation cannot be assumed as causality.
But I think, the main gap is the scope shift here - rating attractiveness and preference.
The final sentence of the prompt is ambiguously written.
A sentence that says "people prefer sweet colas" means that people will buy sweet colas, as opposed to less sweet colas; it implies that packaging and other things are irrelevant, because people have a preference. On the other hand, "people prefer houses with fences" clearly does NOT mean that person will choose a 1-bedroom house with a fence over a full-blown mansion. It means that, given the same house, people will prefer to have a fence than not.
(A) is listed as incorrect because, presumable, the final sentence is intended to have the same meaning as the second example above. However, the conclusion could be read to have a meaning closer to the first sentence above. And under that circumstances, (A) would arguably be a correct answer. Hence, I wonder if this is a legitimate question.
Yes A is the correct answer. it was simple one. Here is an intresting one:
The Earth's rivers constantly carry dissolved salts into its oceans. Clearly, therefore, by taking the resulting increase in salt levels in the oceans over the past hundred years and then determining how many centuries of such increases it would have taken the oceans to reach current salt levels from a hypothetical initial salt-free state, the maximum age of the Earth's oceans can be accurately estimated.Which of the following is an assumption on which the argument depends?(A) The quantities of dissolved salts deposited by rivers in the Earth's oceans have not been unusually large during the past hundred years.(B) At any given time, all the Earth's rivers have about the same salt levels.(C) There are salts that leach into the Earth's oceans directly from the ocean floor.(D) There is no method superior to that based on salt levels for estimating the maximum age of the Earth's oceans.(E) None of the salts carried into the Earth's oceans by rivers are used up by biological activity in the oceans.
Is it E
My explanation
A) It cannot strengthen as the no of years do not depend on whether the quantity is large or small
C) this weakens
D)Irrelevant
B vs E... both strengthens but E is more related to the argument...still not very confident
CR is my weakest section in verbal. I have gone thru the Powerscore CR bible, however when I try to apply the concepts to problems in OG, my accuracy rate doesn't exceed 60%. Please suggest some tips to boost my accuracy.
Since the passage of the state's Clean Air Act ten years ago, the level of industrial pollutants in the air has fallen by an average of 18 percent. This suggests that the restrictions on industry embodied in the act have worked effectively. However, during the same period the state has also suffered through a period of economic decline. The number of businesses in the state has fallen by 10 percent, and the number of workers employed has fallen by 12 percent. It is probable that the business decline, rather than the regulations in the act, is responsible for at least half of the decline in the pollution.
Which of the following, if true, would most seriously weaken the conclusion drawn in the passage above?
(A) During the last ten years, economic conditions in the nation as a whole have been worse than those within the state.
(B) Amendments to the Clean Air Act that were enacted six years ago have substantially strengthened its restrictions on industrial air pollution.
(C) Of the businesses that ceased operating in the state during the last ten years, only 5 percent were engaged in air-polluting industries.
(D) Several large corporations left the state during the last ten years partly in order to avoid compliance with the Clean Air Act.（C）
(E) Due to its small budget, the state office charged with enforcement of the Clean Air Act has prosecuted only two violators of the law since its passage.
@@MANDARACHALAM : its D coz the aothor concludes that decline in businesses caused decline in pollution, however partly. so if D is right it refute the conclusion by showing that because of strict compliance with the clean air act businesses have left the state not vice versa.
I think D cannot be the answer. To weaken, we have to show regulation in the act caused decline in air pollution and not due to business decline. D says large corporations have left due to strict regulation and this justifies economic decline. But no act is passed to limit economic activity but to increase. Here also in the argument, author have meant the same.

Hi Witty,
The number one trick for improving accuracy is prediction. Always try to figure out what the answer should be, or at least what basic form the answer must take; if you already know what the answer will be, you'll be able to find the correct choice more quickly, and you will be much less tempted by distracting trap choices.
Hello puys..lets solve this..plz explain ur ans in detail..Its frm 1000 CR LSAT...i m poor in find the assumption type CR questions..do suggest ny strategy other than four typo.
A mail order company recently had a big jump in clothing sales after hiring a copywriter and a graphic artist to give its clothing catalog a magazine like format designed to appeal to a more upscale clientele. The company is now planning to launch a housewares catalog using the same concept.
The company's plan assumes that
(A) other housewares catalogs with magazine like formats do not already exist
(B) an upscale clientele would be interested in a housewares catalog
(C) the same copywriter and graphic artist could be employed for both the clothing and housewares catalogs
(D) a magazinelike format requires a copywriter and a graphic artist（B）
(E) customers to whom the old clothing catalog appealed would continue to make purchases from catalogs with the new format.
I have tried GMAT CR bible and and did pretty well in OG, CR section,but when i try with 1000 CR my accuracy dropped to 60 to 70 %. I am not able to understand whts wrong wid my CR concepts :(
Pl suggest, if thr is any onther study material i should refer to furthur clear my concepts in CR.
@Shreya09 I would suggest that u stay away from 1000 series..1000sc, 1000cr..brutal sc. They are known more for shaking ur foundations than builiding them up. If you are able to do well in OG and CRBible..smile..you already know the thing. Move on to the other components. Whatever practice you need now should be from full length tests..aka.. mock tests of some reputed firms. Check there, if you are able to apply what you have learned during your prep of CR.

Most of the questions in 1000 cr are from past LSAT sets, so they wont do any favor in your preparation. same can be said about 1000 sc and 1000 rc. stay away from them !!
there are ample good resources in the market, use them to gauge your progress.
Between 1940 and 1945 gasoline consumption in the US dropped about 35 % because of the war time rationing. In the same period, lung cancer in the US white males declined by approximately the same percentage. Between 1914 and 1950 lung cancer mortality increased nineteen fold and the rate of gasoline consumption increased at the same rate. Which of the following facts, if true would weaken the above arguments?
A. For each of the years between 1939 and 1949, lung cancer among urban blacks in the US remained at the same rate.
B. The amount oflead in gasoline increased between 1916 and 1944.
C. After 1950 the gasoline consumption jumped.
D. During world war II, people suffering from cancer were forbidden to drive.
E. Women frrst began driving in large numbers between 1941 and 1951.
