It took me 2.45 mins to understand and answer this question :D
A) 1) Pronoun “they” is ambiguously used to refer to children or parents. 2) Lack of “;” between 2 independent clauses: “A study...” and “it was more likely…” 3) the use of “it was more likely that” change the meaning of the sentence
Incorrect B) 1) The lack of comma prior to “but” indicates that the portion relating to “but” will not be an independent clause. If there is another clause, “;” or other conjunction should be used to connect the first non-underlined clause and the second underlined clause. However, the underlined portion relating to but is a clause and connected to the first clause by a comma.
Incorrect sentence structure.
C) 1) Incorrect structure: clause 1 but when S + V (when S+V = an independent clause). However, “but” in the non-underlined portion is not preceded by a comma. Thus, an independent clause cannot immediately follow “but”. 2) “that of their peers' ” = double possessive. 3) the use of “it was more likely that” change the meaning of the sentence
IncorrectD) Correctly describes two results of the study: A study… showed that X but that Y. Pronoun “they” correctly refers to children. Correct comparison
Correct.
E) 1) Pronoun “they” is ambiguous. 2) Wrong comparison: 3) “behavior” is compared with “their peers”. 4) “to perceive” is prefer to “to be perceiving”
IncorrectHope it helps
