Question

passage 1
identifying sentences with clear reference
read each sentence. three of the sentences have at least one error in usage, but one of the
sentences is correct. identify the correct sentence in each set.
almost everyone who did that chemistry experiment
○ produced nothing but black smoke, which is a
shame.
your miniature pony has won every competition, is
admired by all who see her, and is gentle with small
○ children, which is evidence of your hard work
training her.
○ that the paragliders managed to stay in perfect
formation was amazing.
some people claim that world war ii was the last
○ legitimate armed conflict, which is unlikely to be
true.

Explanation:

• First sentence: "which" incorrectly refers to the entire clause (everyone producing black smoke), but it should logically refer to a noun; this is a dangling modifier issue.
• Second sentence: The list ("has won... is admired... and is gentle") is parallel, but "which" refers to the pony’s traits, yet the structure is awkward, and "training her" lacks clear reference.
• Third sentence: It is a correct noun clause ("That the paragliders... formation") acting as the subject, with no reference errors.
• Fourth sentence: "claims" should be "claim" to agree with the plural subject "Some people"; subject-verb agreement error.

Answer:

That the paragliders managed to stay in perfect formation was amazing.
