(If someone studies for more than 10 hrs, the have a chance of passing while others don't. There is no more chance of passing here in this argument.)

(B) No number of hours will suffice to ensure a passing grade.
(extreme conclusion negating the premise)

(C) If someone does not want to fail the test, he or she had better study for at least ten hours.
according to prof
If you don't study well i.e., for at least 10 hours you are sure to fail or else,
If u study well, you have a chance of passing"


(D) Those who don't study for at least 10 hours will surely fail the course.
surely-extreme word plays the spoilsport here.

(E) The professor's course is one of the harder courses of that year.
Extreme inference same as B.

Hi Mechmeera

Thanks for the explanation. I had a doubt and your explanation showed me that at least someone is thinking the way i am :) . But the difference is that you chose the right answer.
I chose option D. Below is the reasoning:

Professor:
If you don't study well => You will surely fail ---1
study for at least 10 hours => You have chance of passing ---2

I assumed (and this assumption costed me):
study for at least 10 hours = studying well ---3

Hence inference (from 1 and 2)
If you don't study for at least 10 hours => => You will surely fail

Which is precisely option D.

Now, in your explanation for option C (highlighted above), you have basically quoted option D :wink:

But out of C and D, D is a bit extreme compared to C.

I think, for this question, it is easy to eliminate A, B, and E. So we got left with C and D.
The most important thing that differentiate between these two answer is that D said "Those... will fail the COURSE" while the prof. was only talking about this particular test. So yes, D was drawing an extreme conclusion.

My ans 'C'

Prethinking:
If one does not study for the test---> one is sure to FAIL
Study atleast 10 hours---> chance of passing
hence min 10 hours study is required.

Choice analysis:
a. The passage says, "study for at least 10 hours"... this means, minimum 10 hours is fine for passing. So, chances of a person to pass with exactly 10 hours and chances of a person with 12 hours are same.
But as per the sentence, "more than 10 hours study will have more chances" does not make any difference in increasing the chances of passing

b. This statement says "No number of hours will suffice": the prof has clearly mentioned that 10 hours study, so, this statement can't be d ans

c. Seems ok, as this statement covers the argument entirely.

d. I did go for this option because of the word "COURSE". The author has not mentioned the word "course" but the prof only talks about THE TEST.

e. out of scope.

Just because the prof said "...you are sure to fail".. i thought being 'sure' was okay.. i that was a trap :(
We are indeed not supposed to provide certainty/surety/guarantee while inferring.

Actually everything else is fine. C and D would have equal chances of winning if only it wasn't for the words Test/Course.
Just one word to make the decision. Careless reading and you are done! Like i was...

Hi,

lets first see the para..
Quote:
"If you don't study well for the following test, you are sure to fail", said the professor to his students. "Only those of you who study for at least 10 hours have a chance of passing."

the word only tells us that..
1) studying for 10 hrs is a pre prerequisite to pass
2) ofcourse, studying 10 hrs does not guarantee passing, meaning not everyone who studies >10 hrs is sure to pass..

lets see the choioces C and D..
Quote:
(C) If someone does not want to fail the test, he or she had better study for at least ten hours.

(D) Those who don't study for at least 10 hours will surely fail the course.


both C and D convey the same message..
there is nothing as EXTREME, the para with ONLY conveys extreme..
BUTD has 'course' instead of 'test'..
if the mistake is due to oversight, C and D are the answer.
But if it is put purposefully, then we are talking of test in para and course in choice, D can be eliminated on this

One has to look at the source of the Q..
but surely both can pass off as the correct choice..

Hi chetan2u

As you said 1) studying for 10 hrs is a pre prerequisite to pass then how could we eliminate option A

(A) Anyone who studies for more than ten hours has more of a chance of passing the test than those who study for fewer than ten hours.

Eg-
If I say to score 750 in GMAT, one HAVE to STUDY at-least 100 hours.
HAVE TO shows---That its a MANDATE

And there are 2 candidates A studies < 100 hours and B studies >100hrs.
Then its quiet obvious that B has MORE CHANCE to score 750 (Thats what option A says)


Please assist.

Hi,
choice A is extreme....
When we spoke of ONLY, it meant that only people studying more than 10 hrs in a day can pass, so D was not extreme because it was based on the info of para..

but when we say ANYONE in our choice, we talk of the entire group which studies for >10 hrs, but we have never spoken on this group...

if you have a coin, the chances of a head is 50% because the coin is unbiased
BUT can we say the same for a student.. NO

it depends on his capability..
so if we have a very intelligent guy, A, studying for 9 hrs a day, he will not pass due to the restrictions of atleast 10 hrs..
but if a person, B, much below average, studies for 20 hrs, he is also equally likely to fail..
so the chances for both will be 0%, one due to timr restrictions and second due to his own capabilities


if the choice said --a person, A, has more chances of passing if he studies for atleast 10 hrs than if he studies for 6 hrs---
this would still be OK, because you are comparing the same person
or, say, it said--
some person studying for atleast 10 hrs have more chances of passing than all those who study for<10 hrs..
it would also be ok..

Hope it helped..

Hi chetan2u,

I agree with your logic, but judging the students on their capabilities--> Isn't it outside the argument.. :?:

In the above scenario, Can't we say B has MORE CHANCES to pass the test........???
Bcz here I am not saying B WILL DEFINITELY PASS TEST
I am just saying B has more chances over A.

Which of the following can best be inferred, based on the professor's statements ?

(A) Anyone who studies for more than ten hours has more of a chance of passing the test than those who study for fewer than ten hours.

(B) No number of hours will suffice to ensure a passing grade.

(C) If someone does not want to fail the test, he or she had better study for at least ten hours.

(D) Those who don't study for at least 10 hours will surely fail the course.

(E) The professor's course is one of the harder courses of that year.


Here professor is saying "Only those of you who study for at least 10 hours have a chance of passing."Doesn't this statement makes word Surely a necessity?
