Answer:
because she didn't have a car?
Explanation:
The answer is: dangling modifier.
Dangling modifiers are separate from the word they modify, resulting in ambiguity, confusion or nonsense. In the example sentence, it is not clear which animal is walking the wire - whether the dog or the squirrel. Supposing the squirrel (which is about to fall) is walking the wire, a correct version of the sentence would be:
My dog waited for the squirrel to fall, which was walking the wire.
The subordinate clause is the reason why something happens like. Zoe put on her coat Becuse it was cold.
Zoe put on her coat is the main clause and
Because it was cold is the clause
The correct answer is D. This sentence is a perfect example of parallel structure because either after and before AND it in both cases uses simple past tense verbs which are LEARNED AND TRAVELED. The other sentences never show parallelism due to their units are never the same. For example, in letter A , it uses a verb in simple present WALKS AND a progressive tense verb which is TAKING. So, to sum up, for a sentence to be considered parallel, it must be coherent in its structure and internal words. They need to have harmony and unity in tenses as well.
