Answer:
A)The underline independent clauses in the passage above are not linked by parallel structure
Step-by-step explanation:
Parallel structure simply means using a similar or same pattern to indicate that two or more ideas have the same level of importance. It is also known as parallelism.
The underlined (in this case the sentence in quote) independent clause is joined by the coordinating conjunction "and" to show that if he answered all the criticism he would have no time for anything else.
