Complete the following sentences with the correct punctuation and conjunctions: 1. The first half of the twentieth ___ the world was engulfed in war. 2. His works include a novel about the French Revo

Here are the answers to your questions:

Q[1]:
The sentence requires a word to complete the phrase "first half of the twentieth" and a conjunction to connect the two independent clauses. "Century, but" correctly completes the time period and uses a comma before "but" to join the two clauses.
The correct option is:
B) century, but

Q[2]:
The sentence presents a list of the author's works. Since each item in the list is a complex phrase containing internal commas (e.g., "a novel about...", "a television play about..."), semicolons should be used to separate the main items in the list for clarity. The blank needs to complete the description of the first work and introduce the second.
