Answer: D. You can use a pointing word in paragraph 2 that refers to a word in the paragraph 1.
The most important thing to keep in mind when trying to connect paragraphs is that the transition should be as smooth as possible. This means that we should try to avoid a disconnection between paragraph one and paragraph two. A way in which we can achieve this is by using a pointing word in paragraph 2 that refers to a word in paragraph 1. By using this word, we establish the connection between different paragraphs, making the transition smoother.
