Question

Electronic bulletin boards, combining the convenience of a telephone with the massive information storage capacity of a computer, present messages on diverse subjects as astronomy, artificial intelligence, and skydiving.

• A. Diverse subjects as
• B. Diverse subjects that are
• C. Subjects of such diversity as
• D. Subjects as diverse as
• E. A subject as diverse as

Answer 1

The correct option is D Subjects as diverse as

Here, the usage of 'as' is incorrect: "as...as" is the correct construct to use when we are comparing things that are equal in some way (which is what happens in the sentence) Thus D is the best answer.
