The correct answer is letter a. arguments. Cause-and-effect paragraphs and persuasion paragraphs are very similar to arguments. In an argument you are making a claim about a topic. It is also concerned with why things happen (causes) and what happens as a result (effects<span>).</span>
The only noun I know derived from the verb to entomb would be the noun entombment.
It is an abstract noun, which means that it doesn't have a physical shape - you cannot touch it or smell it, just like with love, or hate, or happiness. Entombment is the process of placing a dead body into a tomb, or a grave.
The two meanings for find would be
1. To unexpectedly realize something.
2. To unexpectedly realize the existence of something.
Example of definition 1: I walked inside to find a dog waiting in my room. (Realized the dog was a dog in the room.)
Example of definition 2: I never thought I would find aspartame in diet drinks. (Realized the existence of something, in this case aspartame)
I know it isn't much of a difference, but I'd say the homonym for find would be definition 2.
