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.
Writing that immediately involves the reader's interest and carries them through the final paragraph with no loss go concentration
