]oan got A's on all her homework assignments, so if she had gotten an A on her term paper, she could pass the course even without doing the class presentation. Unfortunately, she did not get an A on her term paper, so it is obvious that she will have to do the class presentation to pass the course.

The argument's reasoning is questionable because the argument
(A) ignores the possibility that Joan must either have an A on her term paper or do the class presentation to pass the course.
(B) presupposes without justification that Joan's not getting an A on her term paper prevents her from passing the course without doing the class presentation.
(C) overlooks the importance of class presentations to a student's overall course grade.
(D) ignores the possibility that if Joan has to do the class presentation to pass the course, then she did not get an A on her term paper.
(E) fails to take into account the possibility that some students get A's on their term papers but do not pass the course.

The argument states that if Joan got an A on the
term paper, then she will be able to pass the
course without doing the class presentation. Since
she didn’t get an A on the paper, the author
concludes that she needs to do the class
presentation to pass the class. Note, however, that
the statement “If A on the paper, then no
presentation” doesn’t tell us anything about what
happens if Joan doesn’t get an A on the paper. It
could be that she won’t need to do the presentation
regardless of her paper grade.

(B) sums up this objection.
(A) introduces as a possibility the necessity of
getting an A on either the paper or on the
presentation to pass the class. There are no
grounds for this assertion, and it doesn’t directly
affect this argument anyway. Since the argument
deals specifically with the necessity of the class
presentation, we certainly couldn’t say, as (C) does,
that it ignores this factor. (D) simply restates the
conclusion of the argument, while (E) discusses the
possibility, irrelevant here, that some students get
A’s on their papers and still fail the course. Since
Joan didn’t get an A on her paper, we don’t really
care about that group of students.

If x then Y -- doesn't mean if not Y , then not X. B is the clear answer.

It looks a simple case of Conditional reasoning fallacy

Premise 1 : Sufficient --> (Not Necessary)
Premise 2 : Not Sufficient
Conclusion: Necessary ? --- Incorrect
Hence B looks the correct answer.

if A then B is the link chain here.
Causal argument type.

Between options A and B

A says if A or B then C (passing) -- this is infact correct.
B says if !A then only B --> gives C (passing) -- this is essentially an assumption in the argument,hence a flaw.

B is clean here.

this is a classic gmat trap

A --> Pass without presentation
~A --> Have to give presentation

Joan got A's on all her homework assignments, so if she had gotten an A on her term paper, she could pass the course even without doing the class presentation. Unfortunately, she did not get an A on her term paper, so it is obvious that she will have to do the class presentation to pass the course.

The argument's reasoning is questionable because the argument

Fact: A's in homework assignment

P: 'A' in term paper Q: Pass the examination w/o presentation P -> Q

Valid conclusion that can be made ~Q ->~P
i.e. She did not pass the examination w/o the presentation -> she did not get 'A' in the term paper.

Did not get 'A' in term paper -> She will have to do the class presentation to pass the course.

Not a valid conclusion.

(A) ignores the possibility that Joan must either have an A on her term paper or do the class presentation to pass the course.
The argument doesn't ignore but takes this point into consideration and states that since Joan didn't get an A, she has to do the presentation. But the question asks us to find the flaw in the argument.

(B) presupposes without justification that Joan's not getting an A on her term paper prevents her from passing the course without doing the class presentation.
A hypothetical scenario: Say out of maximum marks 100, 60 is the passing mark. A grade of 'A' fetches 90% credit and the presentation 10%.
So in case, Joan gets A, she won't have to bother about the presentation to pass the course.
In case she gets B (fetches 80% credit), then also she doesn't have to bother about the presentation.
So as per this hypothetical scenario, it is not necessary that if she doesn't get an 'A', she won't pass.

(C) overlooks the importance of class presentations to a student's overall course grade.
Importance

(D) ignores the possibility that if Joan has to do the class presentation to pass the course, then she did not get an A on her term paper.
This was not ignored but rather stated in the argument. Whereas the question asks us to figure out the flaw.

(E) fails to take into account the possibility that some students get A's on their term papers but do not pass the course.
Joan did not get A, let's focus on that.

Option B

Option B

Lets say the passing marks are 500..and A fetches a score of 100....
NOw let the number of subjects be 5 and she has fetched 400 marks through As in all the four subjects...therefore to score 500 or the passing marks she "MUST" get A in term paper.....which she did not...so she must do a term paper.....one never knows if lowest possible score in presentation itself is 100.....

So i selected C because the argument is not taking the importance of presentation in pasing the exam.

help needed urgently....loosing night sleeps to get the right justification of B.
