Answer:
An active listener.
Explanation:
Be it in a day-to-day interaction or during a speech, a listener can be active or passive. A passive listener is one who is not truly paying attention. He may seem as if he is, though. But there is not real effort to understand the message. <u>An active listener, on the other hand, makes an effort to keep focused on what is being said. He tries to understand the information being presented and uses empathy to connect with the speaker.</u>
It is a metaphor saying that “discovering truth by building up on previous discoveries” this is saying that they were discovering truths about the world faster than others because he/they were working with others to uncover truths.
Answer:
What do you mean by proposal?
Explanation:
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.
