I think this needs diagramming ? I narrowed it down to C and D..but confused. Is there a method to solve these kind of questions.

The professor's conclusion is properly drawn if which one of the following is assumed?

A) None of the students who live off campus is a member of the choir.

B) None of the students who are music majors has failed to join the choir.

C) Some of the students who do not live off campus are not music majors.

D) All students who live on campus are music majors.

E) All students who are members of the choir are music majors.


When boggled by these kind of questions, use a Venn diagram.

The professor concluded that "none of the students who live off campus is a music major" = "all music majors live on campus". Given that all music majors are members of the choir, if all members of the choir live on campus, then all music majors live on campus. Therefore, answer is A.


Why cant it be B, None of the students who are music majors have failed to join the choir, because all the music majors are members of choir.

Thanks.

Okay, so I got a PM stating that the questions I've posted so far are too easy. I guess I need to rectify that! :-D

It's bonus Wednesday ... I will post three questions since I will not be able to provide a question tomorrow (attending a seminar).

I thought about adding my reasoning to the discussion but I think that would be superfluous especially since snipertrader did such a fantastic job!

Quote:
In an experiment, researchers played a series of musical intervals - two-note sequences - to a large diverse group of six-month old babies. They found that the babies paid significantly more attention when the intervals were perfect octaves, fifths, or fourths than otherwise. These intervals are prevalent in the musical systems of most cultures around the world. Thus, humans probably have a biological predisposition to pay more attention to those intervals than to others.

Which one of the following, if true most strengthens the argument?

A) Several similar experiments using older children and adults found that these subjects, too, had a general tendency to pay more attention to octaves, fifths, and fourths than to other musical intervals. -- Does not provide additional info.

B) None of the babies in the experiment had previous exposure to music from any culture.

C) All of the babies in the experiment had been exposed to music drawn equally from a wide variety of cultures around the world.

D) In a second experiment, these same babies showed no clear tendency to notice primary colors more than other colors.

E) Octaves, fifths, and fourths were played more frequently during the experiment than other musical intervals were.


biological predisposition is the keyword I believe. So if we can prove that the babies just were acting out of their instinct I think we strengthen the argument. And B pretty much does that.

The conclusion of the editorialist's argument can be properly drawn if which one of the following is assumed?

A) Anything that exists would continue to exist even if everyone were to stop believing in it.

B) Only if one can have mistaken beliefs about a thing does that thing exist, strictly speaking.

C) In order to exist, an entity must have practical consequences for those who believe in it.

D) If everyone believes in something, then that thing exists.

E) Whatever is true of money is true of financial markets generally.


Confused between C and E. I would take E as argument does not talk about "practical consequences". Eliminated D because I believe the question does not say everyone needs to believe in a thing, it says that if everyone does not believe in something that thing will cease to exist.

hmmmm.....a mindbender
my pick A

argument:money disappears if people stop believing in money....so its not real
A states-Anything that exists would continue to exist even if everyone were to stop believing in it.
assumption: hence money which is not real disappears once belief in it vanishes....so it in reality does not exist for if it existed even if everyone were to stop believing in it it would have not disappeared.

Here's a question that is a little more challenging. I actually had a question on the GMAT with the same argument structure but it was quite a bit longer.

Quote:
Reza: Language requires the use of verbal signs for objects as well as for feelings. Many animals can vocally express hunger, but only humans can ask for an egg or an apple by naming it. And using verbal signs for objects requires the ability to distinguish these objects from other objects, which in turn requires conceptual thought.

If all of Reza's statements are true, then which one of the following must also be true?

A) Conceptual thought is required for language

B) Conceptual thought requires the use of verbal signs for objects.

C) It is not possible to think conceptually about feelings.

D) All humans are capable of conceptual thought.

E) The vocal expressions of animals other than humans do not require conceptual thought.


I thought the answer was D. Can't find an OA posted by Franklin. I think A is wrong because conceptual thought may or may not be required for language (since language consists of both verbal signs for objects AS WELL AS FEELINGS). Therefore, although conceptual thought may be required for ONE PART of language, but not for the other.

Why D is correct: since one of the premise is that "only humans can distinguish between objects", why can't we generalize to assume that ALL humans can? It does not mention MOST/MANY/FEW/SOME.

Somebody please help with this!

IMO..its B
because the question says that " had either one or the other phenomenon failed to occur, this would be consistent with the economy as a whole being healthy."

So if we know that the economy is not doing well than there is a problem with one of the two mentioned areas.

For anyone who decides to answer the question please put down your reasoning ... even if you think it blows! :-D Writing out how you approach the question will help everyone reading the thread.

The following question took me 1 minute 8 seconds to answer...
(This stimulus is approximately the length of the 3 CR questions I saw on the actual exam. Definitely threw me for a loop!)

Quote:
It is proposed to allow the sale, without prescription, of a medication that physicians currently prescribe to treat the common ear inflammation called "swimmer's ear." The principal objection is that most people lack the expertise for proper self-diagnosis and might not seek medical help for more serious conditions in the mistaken belief that they have swimmer's ear. Yet in a recent study, of 1,000 people who suspected that they had swimmer's ear, 84 percent had made a correct diagnosis - a slightly better accuracy rate than physicians have in diagnosing swimmer's ear. Thus, clearly, most people can diagnose swimmer's ear in themselves without ever having to consult a physician.

Which one of the following, if true, most undermines the conclusion?

A) Case in which swimmer's ear progresses to more serious infections are very rare.

B) Most of those who suspected incorrectly that they had swimmer's ear also believed that they had other ailments that in fact they did not have.

C) Most of the people who diagnosed themselves correctly had been treated by a physician for a prior occurrence of swimmer's ear.

D) Physicians who specialize in ear diseases are generally able to provide more accurate diagnoses than those provided by general practitioners.

E) For many people who develop swimmer's ear, the condition disappears without medical or pharmaceutical intervention.

Guys whats the conclusion here ?
I feel its "It is proposed to allow the sale, without prescription, of a medication that physicians currently prescribe to treat the common ear inflammation called "swimmer's ear."
"most people can diagnose swimmer's ear in themselves without ever having to consult a physician." is a sub-conclusion

The economy is doing badly. First, the real estate slump has been with us for some time. Second, car sales are at their lowest in years. Of course, had either one or the other phenomenon failed to occur, this would be consistent with the economy as a whole being healthy. But, their occurrence together makes it quite probable that my conclusion is correct.

Which one of the following inferences is most strongly supported by the information above?

A) If car sales are at their lowest in years, then it is likely that the economy is doing badly.

B) If the economy is doing badly, then either the real estate market or the car sales market is not healthy.

C) If the real estate market is healthy, then it is likely that the economy as a whole is healthy.

D) If the economy is in a healthy state, then it is unlikely that the real estate and car sales markets are both in a slump.

E) The bad condition of the economy implies that both the real estate and the car sales markets are doing badly.


The answer is D.


Can we discuss this question

IMO... C... 1min 30 seconds....

Although,I got this right,I wanna discuss the feasibility of E being a strong contender.
Because if the problem goes away by itself,then why do away with the requirement of a prescription.Let those who have the swimmers ear problem make do without a medication.

Sorry guys for my sporadic posting. I was in NYC for a conference.

Quote:
Bram Stoker's 1897 novel Dracula portrayed vampires - the "undead" who roam at night to such the blood out of living people - as able to turn into bats. As a result of the pervasive influence of this novel, many people now assume that a vampire's being able to turn into a bat is an essential part of vampire myths. However, this assumption is false, for vampire myths existed in Europe long before Stoker's book.

Which one of the following is an assumption on which the argument depends?

A) At least one of the European vampire myths that predated Stoker's book did not portray vampires as strictly nocturnal.

B) Vampire myths in Central and South America, where real vampire bats are found, portray vampires as able to turn into bats.

C) Vampire myths did not exist outside Europe before the publication of Stoker's Dracula.

D) At least one of the European vampire myths that predated Stoker's book did not portray vampires as able to turn into bats.

E) At the time he wrote Dracula, Stoker was familiar with earlier European vampire myths.


Answer:
[Reveal] Spoiler:
D


The author concludes that people should not assume that "vampires turning into bats is essential" because "vampire myths existed in Europe long before Stoker's book".

The answer must contain "vampires turning into bats" and "Europe".

D is the only answer that does so.

I was confused by the usage of "at least one" in the option (D), so if "at least one of EU myths did not portray vampires as able to turn into bats", what about the other myths? What if the other myths mention that vampires are able to turn into bats?

Scientist: A controversy in paleontology centers on the question of whether prehistoric human ancestors began to develop sophisticated tools before or after they came to stand upright. I argue that they stood upright first, simply because advanced toolmaking requires free use of hands, and standing upright makes this possible.

Which one of the following statements, if true, most weakens the scientist's argument?

A) Many animals that do not stand upright have learned to make basic tools.

B) Advanced hunting weapons have been discovered among the artifacts belonging to prehistoric human ancestors who did not stand upright.

C) Many prehistoric human ancestors who stood upright had no sophisticated tools.

D) Those prehistoric human ancestors who first came to stand upright had no more dexterity with their hands than did those who did not stand upright.

E) Many of the earliest sophisticated tools did not require their users to be able to stand upright.

For the last three years, entomologists have been searching for a parasite to help control a whitefly that has recently become a serious crop pest. Believing this new pest to be a variety of sweet-potato whitefly, the entomologists confined their search to parasites of the sweet-potato whitefly. Genetic research now shows the new pest to be a distinct species, the silverleaf whitefly. Therefore, the search for a parasite has so far been wasted effort.

Which one of the following is an assumption on which the argument relies?

A) All varieties of the sweet-potato whitefly are serious crop pests.
B) If a crop pest has a parasite, that parasite can always be used to control that pest.
C) The chances of successfully identifying a useful parasite of the new pest have increased since the proper identification of the pest.
D) No parasite of the sweet-potato whitefly is also a parasite of the silverleaf whitefly.
E) In the last three years, the entomologists found no parasites of the sweet-potato whitefly.
[/quote]

premise 1 : entomologist have been searching for parasite to control a variety of whitefly.
premise 2 : Entomologist confined their search to parasites of sweet potato whitefly
premise 3 : genetic research shows new pest to be a distinct species - the silverfly whitefly
conclusion : search for parasite so far has been a waste

A valid assumption here would be something on the line of parasites of sweet potato are entirely different from parasites of silverleaf whitefly therefore previous search for parasites is no longer useful.

Option D seems to match that assumption and is the correct answer IMO. There is a case a supporter assumption in my view.

Why is the OA B and not D?

A) Many animals that do not stand upright have learned to make basic tools. Talks about basic tools

B) Advanced hunting weapons have been discovered among the artifacts belonging to prehistoric human ancestors who did not stand upright. belonging need not mean they developed those tools?????

C) Many prehistoric human ancestors who stood upright had no sophisticated tools. Many doesn't include all

D) Those prehistoric human ancestors who first came to stand upright had no more dexterity with their hands than did those who did not stand upright. Hand movement has been linked to standing upright on the basis of which the argument is based , making sophisticated tools requires hand movement which is possible by standing upright, Since D states both sanding and not standing upright permits hand movement which is needed for building sophisticated tools, it weaken the argument??????

E) Many of the earliest sophisticated tools did not require their users to be able to stand upright. Talks about use and not development

While 65% of the eligible voters who were recently polled favor Perkins over Samuels in the coming election, the results of that poll are dubious because it was not based on a representative sample. Given that Perkins predominately advocates the interests of the upper-middle class and that the survey was conducted at high-priced shopping malls, it is quite probably that Perkin's supporters were overrepresented.

Which one of the following statements most accurately expresses the main conclusion of the argument?

A) The poll was intentionally designed to favor Perkins over Samuels.

B) Samuel's supporters believe that they were probably not adequately represented in the poll.

C) The poll's results probably do not accurately represent the opinions of the voters in the coming election.

D) Samuels is quite likely to have a good chance of winning the coming election.

E) Those who designed the poll should have considered more carefully where to conduct the survey.

IMO C, what is OA?

31. It is proposed to allow the sale, without prescription, of a medication that physicians currently prescribe to treat the common ear inflammation called "swimmer's ear." The principal objection is that most people lack the expertise for proper self-diagnosis and might not seek medical help for more serious conditions in the mistaken belief that they have swimmer's ear. Yet in a recent study, of 1,000 people who suspected that they had swimmer's ear, 84 percent had made a correct diagnosis - a slightly better accuracy rate than physicians have in diagnosing swimmer's ear. Thus, clearly, most people can diagnose swimmer's ear in themselves without ever having to consult a physician.

Which one of the following, if true, most undermines the conclusion?

A) Case in which swimmer's ear progresses to more serious infections are very rare.
B) Most of those who suspected incorrectly that they had swimmer's ear also believed that they had other ailments that in fact they did not have.
C) Most of the people who diagnosed themselves correctly had been treated by a physician for a prior occurrence of swimmer's ear.
D) Physicians who specialize in ear diseases are generally able to provide more accurate diagnoses than those provided by general practitioners.
E) For many people who develop swimmer's ear, the condition disappears without medical or pharmaceutical intervention.

While 65% of the eligible voters who were recently polled favor Perkins over Samuels in the coming election, the results of that poll are dubious because it was not based on a representative sample. Given that Perkins predominately advocates the interests of the upper-middle class and that the survey was conducted at high-priced shopping malls, it is quite probably that Perkin's supporters were overrepresented.

I think the answer should be C.

"it is quite probable that Perkin's supporters were overrepresented" is a statement from the question stem. This seems to indicate that
C) The poll's results probably do not accurately represent the opinions of the voters in the coming election. Key words "probably" and "represent". What's the original answer?
