The prefix "de-" means to deduct, or remove from. So, de- + attach, would mean to remove something from holding on to another thing. Apply that to the situation, and the pedal straps "detach", meaning they stop holding on to his ankle. Petal straps connect Andre's foot to his pedals, but when he falls, they disconnect, and the strap no longer holds his foot to the petal. Basically the word detach means to release hold of his foot, so the petals no longer hold his foot to his bike.
The word sharpen is a word that leads you to believe you are talking about knives. It has nothing to do with knives.
A: implies the same thing. It just isn't so.
B: dull is also a term that is associated with knives. In this case, it is factually false (you want to "sharpen" something, not make it dull) and it is not to be associated with a knife. Don't choose B.
Sharpen your brain means that you become more agile in your thinking. None of the choices really says that. So you have to pick something that is the "best" choice of 4 very poor ones. I suppose C is the answer, but I'm holding my nose as I tell you this. (C as an answer stinks).
D is 1/2 true but you have to associate it with thinking. I don't think there is a really good answer, but of those there, I would pick C.
I believe the answer is B. You may Google some examples of a prepositional phrase though to be sure. :)

Explanation: i took the quiz of edge.
The answers are C and D Good is not a noun, and thus it cannot be a subject, because it is an adjective. B - gardeners, is a noun, but not a subject, it is the object of this sentence. C is the correct answer, it is a pronoun, which substitutes a noun, so they basically mean the same. And D is also correct, because it is the "doer of the action", it is falling. You can easily find the subject by asking the question - Who is doing it?
