This is a rather personal question, and I can't answer for you, but I can give you my opinion.
When Macbeth says that line, he is referring to the meaninglessness of life. He is saying that life isn't really worth living because it is just a fleeting moment in time, and will eventually end, no matter what you do about it. He tried hard to fight for his ambition and become a king, and he did, but he died nevertheless, thus reaffirming his belief that life is 'signifying nothing' in the end.
Personally, I disagree with his opinions. Yes, life is going to end and we aren't going to live forever, however, we have to make do with what we were given. We aren't supposed just to lie down and wait to die - we should live our life to the fullest and make the most of it while we still can. As the famous aphorism goes, Carpe diem (Seize the day)!
Answer:
he does his homework every day
Answer:
We say that nonverbal communication is <u>ambiguous</u>.
Explanation:
According to the passage we are completing here, our actions may have more than one interpretation. Anything that has more than one interpretation is, by definition, ambiguous. Ambiguity is so often related to non-verbal communication because people are likely to interpret what they see according to their own opinions, values, ideas, and context. Suppose, for example, that your best friend has tears in her eyes. You don't know what happened and, since she hasn't had the chance to explain it yet, you assume she is sad because of something bad. You do that because you're filling in the context with your own opinions and values. You've learned to associate tears to sadness. It may very well be that she is happy and relieved after receiving good news about a loved one who was discharged from the hospital.
The correct answer seems to be number four - not enough. It both suits grammatically, and sentence-wisely.
