a) properly constructed sentence
b) lacks parallel parts
c) dangler
d) misplaced part
a) properly constructed sentence
a) properly constructed sentence
The correct answer is (b) lacks parallel parts.
Explanation:
In this sentence, the phrase "the filing rules must be learned" lacks parallel structure. The first part of the sentence, "To keep your files in order," sets up an expectation for parallelism, meaning that the subsequent phrases or clauses should be structured in a similar way.
To correct this issue, the sentence could be rewritten as follows:
"To keep your files in order, you must learn the filing rules."
In this revised sentence, both parts have parallel structure: "To keep your files in order" and "you must learn the filing rules."
