CR challenge -2

by abhasjha » Mon Apr 27, 2009 8:13 am
The new perfume Aurora smells worse to Joan than any comparably priced perfume,
and none of her friend likes the smell of Aurora as much as the smell of other
perfumes. However, she and her friends must have a defect in their sense of smell,
since Professor Jameson prefers the smell of Aurora to that of any other perfume and
she is one of the world’s foremost experts on the physiology of smell.

From the information presented in the support of the conclusion, it can be
properly inferred that

(A) none of Joan’s friends is an expert on the physiology of smell

(B) Joan prefers all other perfumes to Aurora

(C) Professor Jameson is not one of Joan’s friends

(D) none of Joan’s friends likes Aurora perfume

(E) Joan and her friends all like the same kinds of perfumes

IMO [spoiler][D][/spoiler]

[A]- We really don't know if there is anyone in Joan's friend who is an expert, so cannot infer that from the stimulus
- We have been just told about Aurora perfurme that smells not good on Joan and her friends does not like that either
[C]- We really don't know that for fact. Even if she is, then she would not have like Aurora because Joan's friends don't smell of Aurora
[D]- This is the correct one
[E]- It's been stated that Joan and her friends like the smell of other perfumes, but that does not mean they all like the same kind of perfumes.

inference is something which we derive from an argument

D reiterates the premise
The new perfume Aurora smells worse to Joan than any comparably priced perfume,
and none of her friend likes the smell of Aurora as much as the smell of other
This is an inference question and not must be true. so please pay attention

I am confused between C and E

I am more inclined to E

can anyone tell me how they have eliminated E

(A) none of Joan’s friends is an expert on the physiology of smell
No evidence this is true. If it were, it would mean experts would have different opinions, which is allowed.
(B) Joan prefers all other perfumes to Aurora
This is not indicated. It is indicated that Joan prefers all other perfumes to this one, for this price range only.
(C) Professor Jameson is not one of Joan’s friends
In my opinion, this is the correct answer. The taste of the friends and the prof differer significantly.
(D) none of Joan’s friends likes Aurora perfume
This is not stated. Joan's friends could like every perfume they know, but like Aurora the least.
(E) Joan and her friends all like the same kinds of perfumes
This statement is too broad.[/i]

OA- C

Official explanation follows :


It's virtually impossible to pre-phrase an inference here; the only course is to look through
the choices till you find something that strikes you as deducible. We're told that none of
Joan's friends likes Aurora's smell as much as the smell of other perfumes. We're also told
that, by contrast, Jameson does like the smell of Aurora more than that of any other
perfume. Plainly, Professor Jameson is not one of Joan's friends. This is something of a
formal logic question in disguise.
(A) Although the stimulus fails to identify any of Joan's friends as an expert on the sense of
smell, that’s not sufficient reason to conclude that none of her friends is such an expert
(though assuredly not an expert of Professor Jameson's stature in the aroma world).
(B) Joan is said to prefer the smell of all comparably priced perfume to Aurora's smell; there
may be a perfume in another price range that she likes even less.
(D) subtly changes the terms of the argument. Joan's friends don't like the smell of Aurora
as much as the smell of other perfumes, but that doesn't mean that none of them likes
Aurora at all. Maybe some of them like all perfumes

(E) goes beyond the scope. How Joan and her friends feel about other kinds of perfumes is
an irrelevant issue. The only issue that the stimulus deals with is how they feel about
Aurora's smell compared to other perfumes' smells.
• If you’re aware of small changes in wording that alter the terms of the discussion
(e.g. “other perfumes” vs “other comparably priced perfumes”) you can quickly
discard improper inferences.
• When you have trouble prephrasing, don't try to force it; go immediately to the
answer choices, where the proper inference is waiting
