A statement is given, followed by two assumptions I and II. You must assume everything in the statement to be true, and on the basis of the information given in the statement, decide which is a logical assumption.
Statement: Richa has spent a lot of hours every day preparing for the upcoming final term university examination, but she is still not sure how she will perform in it.
Assumption:
I. Richa may perform well in the final term examination.
II. The final term exams are a very difficult.
From the given statement, it clearly follows that Richa may or may not perform well in the final term examinations. Thus, assumption is implicit. However, we cannot imply anything about the difficulty level of the exam from the statement. Thus, assumption II is not implicit. Hence, the correct answer is (A).
