Explanation:

Question 28

To emphasize quickness, "mere" (meaning only, just) best conveys that the time is very short. "a few" is neutral, "a matter of" is less emphatic, and "NO CHANGE" (assuming original was less effective) doesn't emphasize speed.

The sentence is the last step in the photo - developing process, so "Finally" (indicating the last action in a sequence) is appropriate. "In conclusion" is for summarizing ideas, "Thus" is for causation, and "Nevertheless" is for contrast.

The correct structure is using a dash or no parentheses for the explanatory phrase. Option B uses a dash to explain the purpose of the oil, which is clear. Option A has unnecessary parentheses, C has incorrect commas, and D is similar to A but without parentheses but B's dash is better for emphasis.

Answer:

D) mere
