Learn English – What are the differences between “know”, “know about”, and “know of”

The two expressions are fairly close in meaning and can be used interchangeably with the following nuances:

"force an idea on the others" implies that the idea was opposed by the others but through some sort of aggression (verbal or otherwise), the others had to accept the idea.

"impose an idea on the others" gives more of an impression that the others didn't want to go along with idea for whatever reason but acquiesced though they might feel there was either some coersion or at the least, an obligation to accept the idea.

Anytime a person returns communication it can be called a response or a reply, while an answer is a form of response which is a solution to a problem or question. So response and reply are generic and can be used in any situation, while answer is more specific in its usage.

So if you asked a question or asked for a solution to a problem, and the person gave it to you, then you can say "Thanks for your quick answer". If it was not in one of these categories, then use response or reply since these are both generic.

And if you are still in doubt, remember that because response is generic you can use it in any situation.
