which choice completes the text so that it conforms to the conventions of standard english?
a industrial
b that of industrial
c those of industrial
d those by industrial

Explanation:

To solve this, we analyze the comparison. The sentence compares the "decibel profile" (a singular noun) of elevated metro lines to the decibel profile of industrial construction zones. We need a pronoun that refers to a singular noun ("profile").

• Option A: "industrial" would compare the decibel profile to industrial construction zones (the zones themselves), not their decibel profile. Incorrect.
• Option B: "that" is a singular pronoun used to refer to a singular noun (here, "profile"). "that of industrial construction zones" means the decibel profile of industrial construction zones. This is correct.
• Option C: "those" is plural, but "profile" is singular. Incorrect.
• Option D: "those by industrial" is grammatically incorrect and uses a plural pronoun for a singular noun. Incorrect.

Answer:

B. that of industrial
