Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer : Statement : Never before such a lucid book was available on the topic. Assumptions : I. Some other books were available on this topic. II. You can write lucid books on very few topics.

The correct answer is: C. Either I or II is implicit

The statement “Never before such a lucid book was available on the topic” does not provide enough information to determine whether or not assumption I (Some other books were available on this topic) or assumption II (You can write lucid books on very few topics) is true. It is possible that other books were available on the topic, but they were not as lucid as the book being discussed. It is also possible that lucid books can be written on many topics, but this particular topic has not been well-covered in the past.

Therefore, either assumption I or assumption II could be true, but we cannot say for sure without more information.
