Answer:
I believe the best answers are:
blank 1 -- C) that has
blank 2 -- A) NO CHANGE
Explanation:
The original sentence, "...the US government has the power to take custody of land when having historical significance or great natural beauty" is a bit ambiguous. Who has historical significance? We assume it is the land. But, in the way it is phrased, it could also be the government. To eliminate such ambiguity, the best option is letter C) that has. It will help determine a certain land can be taken. What land? The one that has historical significance.
As for the sentence, "The designation of a territory as a national park, national monument, or other types of protected area can limit activities," I don't see any reasons for changes. Especially because of the word "other", which needs to be completed by a plural noun - eliminating options B and C. Letter D wouldn't be incorrect, but the transformation of "protected area" into an adjective for "types" is unnecessary. The sentence is perfect the way it is and, therefore, needs NO CHANGE.
Answer: Not fully.
Explanation: Even in communist societies, where the concept is for everyone to have the same thing, there is tension between different groups for inherent traits. It depends on your definition of "differences". If there were a group of people who knew nothing of racism, sexism, or any other -ism, it still wouldn't be possible for a society to be entirely accepting of others' differences. For example, maybe someone doesn't like someone else because of the pitch of their voice or a certain personality trait. Those are differences that you may not accept. Other differences could be actions some view as unforgivable, such as theft. In conclusion, I don't believe it's possible to have a society that fully accepts one another's differences. It is possible to have one that gets along together well, or even claims to love each other in all ways, but there will always be conflict between person to person and person to self. It's just life.
