Answer:
The correct answer is C.
Step-by-step explanation:
In the first passage, while the author is providing information, he is also trying to persuade the reader to agree with his point of view. He seeks to convince his audience that national parks are beneficious and that they allow to preserve the land so that future generations can enjoy it.
The second passage merely concentrates in giving accurate information to the reader. The author does no express any type of personal opinion, nor he seeks to convey any idea in particular.
