The race began modestly, in 1970, with only 110 people in the race. this revision combines sentences (4) and (5) in paragraph 3. choose which sentence type best describes this revision. a) simple sentence b) complex sentence c) compound sentence d) compound-complex sentence

So based on the given revision above which is the combined sentences 4 and 5 in the paragraph, the type of sentence that best describes this would be a simple sentence, and that would be option A. This is a simple sentence because it only consists of a single clause having one subject and one predicate. Hope this answers the question.
