Hi, here you are:
I choose the last one: x2=3/4
I think it should be muscles of the veins and arteries since they move blood through the bloodstream
Multiple meaning words or homonyms words are those which are spelled and often pronounced alike, but they have different meanings. In this case, the best choice could be Degrees, because it has completely different meanings,such as those referred to temperature, for example,<em> 20 degrees celsius </em> or any other measurement; it could also mean an educational level, when you obtain a degree after studying a course or the amount or level of something, like for example, <em>this brand has a high degree of quality. </em>
I think it is A, I'm not sure though
