Choose the only correct sentence: 1. She felled down the hill because her walk boots were not tied tightly 2. She fell down hill
because her walking boots weren’t tied tight 3. She fell down the hill because her walking boots were not tied tightly 4. She fallen down the hill because her walked boot were not tied tight
Sentence three is the correct sentence. All of the others have some grammatical error in them. In the first, "felled" is incorrect and not a word. It also says "walk boots" instead of the correct verbal adjective "walking boots." In the second, "weren't" is not usually considered very academic and "tight" should be in the adverb form "tightly." Number four is wrong because it used "walked boots" instead of of "walking boots" and "tight" instead of "tightly." "Fallen" is incorrect in number 4, because it should have been "had fallen" if one was going to use the verb "fallen."
