Authors and speakers often use rhetorical devices to make their messages more compelling. One type of rhetorical device is parallel construction (repeated phrasing or sentence structures). How does Churchill use this device in his 1940 speech to Parliament, and how does it add to the speech? Include examples from the text.

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

i think the answer is d.

the meaning of the word broods in verb form is a family of animals used in section 2
