<span>it's D: All astronauts had master’s or doctorate degrees, but only two were jet pilots; consequently, the astronauts with no flight experience had to complete one year of flight training.
The answer to your question would be that the sentence that correctly shows where a semicolon is needed in the sentence is the following one: All astronauts had master's or doctorate degrees, but only two were jet pilots; consequently, the astronauts with no flight experience had to complete one year of flight training.
Explanation:
The sentence above contains the conjunctive adverb <em>consequently.</em> You should always use a period or semicolon before the conjunctive adverb when separating two independent clauses. That is why the last sentence is the one that is correctly punctuated.
If you're referring the classic text by author John Bunyon, "<span>He is against war because it misuses faith and reason to justify it" is the best answer. He was imprisoned for twelve years for these views. </span>
