1) If a student is not required to hand in written homework based on the reading assignments, will not complete all of the reading assignments.

2) If the students in a course are given several reading assignments and no written assignments, no student in that course will receive a high grade for the course.

Suggested: If the student is not given any written assignment they won't complete all of their reading assignment

Conclusion: If the student doesn't completes all the reading assignment than he definitely won't get high grades.

The conclusion of the argument follows:

(A) No student who completes anything less than all of the reading assignments for a course will earn a high grade for that course.
(The passage concludes If the student doesn't complete their reading assignment they won't get high marks) (Correct)

(B) Any student who completes all of the reading and written assignments for a course will earn a high grade in that course. (Its not mentioned that the student who complete all of the assignments written and reading one both will secure high marks) (Wrong)

(C) All highly motivated students who complete all of the reading assignments for a course will receive high grades for that course.(same as B, no perfect chances to score high grades if the student completes their assignment)

(D) If highly motivated students are required to hand in written homework on their reading assignments, then they will complete all of their reading assignments.(Can't be concluded from the passage)(out of scope)

(E) Some highly motivated students will earn high grades in a course if they are required to hand in written homework on their reading assignments.(No stats given that the student completing assignments will secure high marks)

My Analysis:

As per argument: No student completes the reading assignments if there is no written homework corresponding to them. This includes the highly motivated children of the class too.

Conclusion: If students are given only reading assignments and no written assignments, no student will receive a high grade in that course.

Qtn asks the assumption on which conclusion is based


(A) No student who completes anything less than all of the reading assignments for a course will earn a high grade for that course. CORRECT: it clearly states that if all assignments are not completed, then high grades are not given. It is in line with the author's conclusion.
(B) Any student who completes all of the reading and written assignments for a course will earn a high grade in that course. WRONG: As the argument talks about the scenario where the only reading assignments are given and no written assignment.
(C) All highly motivated students who complete all of the reading assignments for a course will receive high grades for that course. WRONG as it talks about only a small section of students "highly motivated students". It means only highly motivated students will get high grades and not other students if they too complete all reading assignmnet
(D) If highly motivated students are required to hand in written homework on their reading assignments, then they will complete all of their reading assignments. WRONG as it talks about only a small section of students "highly motivated students".
(E) Some highly motivated students will earn high grades in a course if they are required to hand in written homework on their reading assignments. WRONG as it talks about only a small section of students "highly motivated students".

This one is actually quite straightforward. Let’s first look at the conclusion:

“... if the students in a course are given several reading assignments and no written assignments, no student in that course will receive a high grade for the course”

The relationship between written homework and reading assignments is mentioned in the first sentence of the passage. Important to notice here is that having no mandatory written homework does not only lead in students not doing the writing but also in not even reading
the assigned text. This is the crucial link to answer this question right because - in real world circumstances - it would be quite logically to assume that even when there is no written homework students will still read the text to be able to receive a good grade in the exam.

Let’s look at (A):

(A) No student who completes anything less than all of the reading assignments for a course will earn a high grade for that course.

In line with pre thinking - bingo! How could the whole argument hold true if there would be students receiving high grades without reading all assignments? It can’t hold true.

Lots of people picked (B) which is a typical reverse causality trap. Its like saying “People who don’t have a driving license can’t be good drivers” - which does not translate into “Everyone who has a driving license has to be a good driver”

this we are sure about. because this connects with the premise and the conclusion.
(B) Any student who completes all of the reading and written assignments for a course will earn a high grade in that course.
Any student who completes all may or may not get high grads because we dont know if reading assignements or writen home work is the only criteria for high grades.
(C) All highly motivated students who complete all of the reading assignments for a course will receive high grades for that course.
All highly motivated students will get high grades? not true may or may not get. we dont have premise supporting this that all motivated students doing the work get high grade.
(D) If highly motivated students are required to hand in written homework on their reading assignments, then they will complete all of their reading assignments.what if they copy one anothers homework? this will not be true then.
(E) Some highly motivated students will earn high grades in a course if they are required to hand in written homework on their reading assignments.
we dont know, will ther be no final test? or is ther no other criteria for grading?

Any student who is not required to hand in written homework based on the reading assignments in a course will not complete all of the reading assignments. Even highly motivated students will neglect their reading assignments if they are not required to hand in written homework. Therefore, if the students in a course are given several reading assignments and no written assignments, no student in that course will receive a high grade for the course.

The conclusion of the argument follows logically if which one of the following is assumed?

(A) No student who completes anything less than all of the reading assignments for a course will earn a high grade for that course. -- CORRECT, links the conclusion that high grade = all reading assignments (because in absence of writing assignment, students don't complete reading assignments)
(B) Any student who completes all of the reading and written assignments for a course will earn a high grade in that course. -- The effect of writing assignment on grades is not mentioned in the passage
(C) All highly motivated students who complete all of the reading assignments for a course will receive high grades for that course. -- The passage is about all students; highly motivated students are just part of whole used as example
(D) If highly motivated students are required to hand in written homework on their reading assignments, then they will complete all of their reading assignments. -- This is not the main point of the passage
(E) Some highly motivated students will earn high grades in a course if they are required to hand in written homework on their reading assignments. -- The lack of completion of reading assignment is at issue in the passage, not that of writing assignment

So, the answer is A

The argument centers around finding the supporter assumption as clearly there is a jump from failing to complete reading assignments to obtaining a high grade. First two sentences are premise whereas the last sentence is the conclusion. Observe that the second sentence does not convey any new information.

First statement already says that 'For all students, If no written homework, then reading assignments will be incomplete'
Second statement says that 'For highly motivated students, If no written homework, then reading assignments will be incomplete'

Finally, conclusion says 'If no written homework, then no high grade'

From the first two statements we know that If no written homework then reading assignments will be incomplete. Hence for the author to logically draw the conclusion he or she needs to assume that If reading assignments are not completed, then no high grade or in other words For a high grade, completing reading assignments is NECESSARY.

Choice (A) is another way of saying that completing reading assignments is NECESSARY
Choice (B) says that completing reading assignments is SUFFICIENT to earn a high grade. We cannot say this as there could be many criteria that need to have been met in order to earn a high grade. For example, attendance must be 70 percent etc
Choice (C) again makes reading a SUFFICIENT condition
Choice (D) does not follow from the argument. Also, since it does not talk about high grades, it does not link the premises to the conclusion.
Choice (E) again makes reading a SUFFICIENT condition.
