Answer:
3M is a company with a culture that lets its employees experiment. Because it allows employees to try new things and even use company equipment to do it, the employees have come up with a lot of good ideas, which have led to new products being developed.
Explanation:
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 (:
B, because it doesn't exactly quicken as in a, no odd characters are introduced, and these not really any details we need to know that are left out. I picked B because there are intentionally larger words.
