Read the selection below and answer the question. but when shall we be stronger? will it be the next week, or the next year? will it be when we are totally disarmed, and when a british guard shall be stationed in every house? shall we gather strength by irresolution and inaction? which of the following best describes the quotation? imperative statements rhetorical questions appeals to ethos exclamatory sentences

The correct answer is rhetorical questions.
Rhetorical questions are the types of questions which don't necessarily need an answer. So when the author writes "But when shall we be stronger?" he doesn't really need anyone to answer him - it is just his style of writing.
Imperative sentences are some kinds of orders, appeal to ethos would mean that the author is giving evidence to support his or her claims, and exclamatory sentences have an exclamation mark.
