The headmaster at Leawood Day School noticed that scores on math tests were lower this year than in previous years. This year, all students took math courses during the first period of the school day; in years past, they had taken math during the final period of the day. Reasoning that the students perform better on math tests when they are fully awake, the headmaster concluded that test scores would be higher if math classes were moved to the end of the day.

The headmaster’s reasoning depends upon which of the following assumptions?

(A) It would be possible to reconfigure the school’s schedule to accommodate having math classes in the afternoon.
(B) Several schools similar to Leawood Day School hold math classes in the afternoon.
(C) The quality of the teaching has little bearing on test scores.
(D) This year the math department started using new, unfamiliar curricular materials.
(E) Students are more likely to be fully awake during the final period of the day than they are during the first period of the day.

+1 for E.

Stimulus :
Premise : Math test's scores were lower this year than in previous years
Premise : This year, all students took math courses during the first period of the school day (students are NOT fully awake during the first period)
Premise : Last year, they had taken math during the final period of the day (students are fully awake during the final period)
Conclusion : Students perform better on math tests when they are fully awake, an so the headmaster believes that test scores would be higher if math classes were moved to the end of the day for students are fully awake during the final period.

(E) Students are more likely to be fully awake during the final period of the day than they are during the first period of the day. --> Correct, negate the statement and see how it affects the conclusion.

Hence, E.

Only E is showing the gap between the arguments. If E is false then argument will fell apart.

E) Students are more likely to be fully awake during the final period of the day than they are during the first period of the day.
just follow the negation:- students are not more likely to be fully awake during the final period of the day than they are during the first of the day.

I know the answer is option E, which is adherent to the argument gap in premise and conclusion.

But can u explain option C, and please tell whether option C had been mentioned as " quality of teaching has remained the same " , then would it could also be a possible assumption

C) The quality of the teaching has little bearing on test scores.
Negate C: The quality of the teaching has NO little bearing on test scores.===The quality of the teaching has MORE bearing on test scores.

does this affects the conclusion in anyway.

Therefore this is not correct

I'm confused between C & E
Here the head master's reasoning is that students perform better on math tests when they are fully awake. Based on this reasoning he has drawn a conclusion that test scores would be higher if maths classes were moved to end of the day. Now the question asks us for the assumption based on which the reasoning is dependent and not the conclusion. I think the reasoning provided by him is based on his assumption that no other parameter affects a student's performance. Thus c should be the answer
Whereas if question was about assumption for conclusion, it would have been E.
Experts please help!
