Answer:
Hi! I'm afraid that your question is incomplete since you didn't attach the text you're referring to. I tried to look up the information on the Internet, but there's not much I can do without the name of the author or name of the text. Anyways, I'll try to help you by guiding you to write the correct answer yourself.
Step-by-step explanation:
In order to answer this questions, the first thing you have to do is to carefully read the text. The task requires you to understand the content and analyze which is its central idea. Ask yourself: which is the objective of this text? What is the text trying to tell me? Your answer to these questions will clarify the central idea of the text. Another good excericise to figure it out is to tell a family member or a friend what is the text about once you read it. You will be explaining the central idea of the text with your own words, without even noticing.
Once you figure out the central idea, see which of the options best fit your understanding, there you'll have the answer to the task.
You'll do great!
