Read this paragraph.
When coal was used to heat homes, it frequently left soot stains on the walls. (2) Brothers Cleo and Noah McVicker, who owned a cleaning product company created a doughy substance to help people remove this soot. (3) Over time, as natural gas becomes more common, people had little need for soot cleansers, and the McVickers’ family company struggled to stay in business. (4) Then one day Joe McVicker, Cleo’s son, learned that his sister-in-law had been using the substance for art projects in her classroom, so he remarketed the product as the toy known today as Play-Doh.

Correct answer: C
This is the answer (C)
The question asks for the pair of revisions needed to correct the errors in the paragraph, which appear in sentence 2 and sentence 3.
Option C is correct because it is the only choice that revises the errors in both sentence 2 and sentence 3.
In sentence 2 (Option C and Option D), a comma needs to follow the word “company” to set off the phrase “who owned a cleaning product company.” A comma is necessary because the phrase is a nonrestrictive clause: the phrase provides extra information about Cleo and Noah McVicker’s line of work, but the phrase is not necessary in order to understand the meaning of the sentence.
The second error is in sentence 3 (Option A and Option C), which incorrectly shifts the verb into the present tense. The clause “as natural gas becomes more common” should be “as natural gas became more common.”
The comma after the word “homes” in sentence 1 (Option A and Option B) is necessary for separating the subordinate clause “When coal was used to heat homes” from the main clause.
In sentence 4 (Option B and Option D), the word “re-marketed” is in the past tense established in the rest of the paragraph and should not change to the past perfect tense “had re-marketed.”
