Choose the correct word to complete the following sentence:

My research focuses on the ______ half of the eighteenth century.

Correct option is B

The correct answer is: (b) latter

• Later – comparative form of "late," generally used when comparing two times or events, but not ideal in this context.

• Latter – refers to the second of two parts or items previously mentioned or implied, and is often used with expressions like "the latter half."

• Late – usually refers to something that happened in the past or someone who has died, not suitable here.

• Lateness – noun form, refers to being late, incorrect in this sentence.

So, the complete sentence is:

My research focuses on the latter half of the eighteenth century.
