Explanation:

Question 28

To emphasize quickness, "mere" (meaning only/just) best conveys the limited time. "Nominal" (A) doesn't stress speed, "a few" (B) is less emphatic, "a matter of" (C) is neutral. So D is correct.

The text describes a sequence of steps in photo development. "Finally" (B) fits as the last step. "In conclusion" (A) is for summarizing, "Thus" (C) for cause - effect, "Nevertheless" (D) for contrast. So B is correct.

The phrase explains the purpose of using lavender oil. An em dash (—) is good for emphasizing the purpose. Option B with the em dash is correct. A has unnecessary parentheses, C has incorrect commas, D lacks the emphasis of the em dash.

Answer:

D) mere
