Official Explanation KaplanRead the Original Sentence Carefully, Looking for Errors:This is a faulty parallelism error. In the sentence, "the legislature" is currently paired with "England" in an unsuccessful merger attempt. We need to match legislature to legislature, or country to country.
Scan and Group the Answer Choices:Choices (C), (D), and (E) provide options that match legislature to legislature. The remaining answer choices do not correct this error.
Eliminate Wrong Answer Choices:Choice (A) is incorrect, since we identified an error in the sentence in Step 1.
Choice (B) also refers to merging Scotland's legislature with England itself (rather than England's legislature).
Choices (B), (D), and (E) talk about merging one thing "and" another. However, the correct idiom for this phrase is to merge one thing "with" another.
Choice (C) correctly compares the legislature of Scotland "with that of England".
TAKEAWAY: Two-part constructions, even if they are not comparisons, need to match logically in the same way as comparisons.
