A:
Ony Assumption (I) Is Implicit
B:
Only Assumption (II) Is Implicit
C:
Neither Assumption (I) nor (II) Is Implicit
D:
Both Assumptions (I) And (II) Are Implicit
Explanation
The statement suggests that there is no guarantee that highly brilliant and industrious students will excel in written examinations. This implies that assumption (II) is implicit, i.e., brilliant and industrious students cannot always write good answers in the exam.
However, the statement does not suggest that written examinations are good mainly for mediocre students. Therefore, assumption (I) is not implicit.
Hence, the correct answer is (B) only assumption (II) is implicit.
