"Scrooge hung his head to hear his own words quoted by the Spirit, and was overcome with penitence and grief." Because this shows the actions of sorrow from scrooge, the reader knows he regrets the way he acted earlier and therefore this shows scrooge is showing that he is ashamed by his own actions.
Take out the bare parts: the subject and verb: forests _____.
If you still can't tell, assimilate it to something easier. Let's say "they are".
Both "forests" and "they" are plural.
Now, you wouldn't say "they is"; the verb also has to be plural.
Back to "forests _____": forests contain. (A)
By the Process of Elimination, C and D are incorrect. You also cannot fill it out with "has contained" because that is singular. It would be "have contained", but that does not make sense in the context.
So, the final answer would sound like this:
The forests near my home contain many different types of trees and plants.
I hope that clarifies the problem (:
Do you have picture of the section that you could share so I can help? :)
