Don’t lose patience, things will improve by and by A. soon B. finally C. gradually D. unexpectedly

The correct answer is C. gradually.

The phrase “by and by” means “in the future” or “eventually.” It is often used to express the idea that something will happen slowly but surely. In the context of the sentence “Don’t lose patience, things will improve by

and by,” the speaker is encouraging the listener to be patient and not give up, because things will eventually get better.

The other options are not as accurate. Option A, “soon,” implies that things will improve quickly. Option B, “finally,” suggests that things have been bad for a long time and are finally starting to improve. Option D, “unexpectedly,” implies that things

will improve without warning.

In conclusion, the correct answer is C. gradually.
