Answer
A
deleting the last sentence of the first paragraph
B
deleting the first sentence of the second paragraph
C
adding a transition at the beginning of the second paragraph
D
adding another sentence with evidence at the end of the first paragraph
Explanation
The first paragraph argues against a Mars mission because of its cost and the needs of Earth. The second paragraph shifts to a possible benefit of Mars exploration: finding resources, so a transition at its beginning would help connect the ideas and show that the writer is considering another side. For example, “On the other hand” signals this contrast. The paragraphs can keep their existing sentences because both contribute relevant ideas.
