Number 2:

01. What is the topic of this passage?

Option D. Ways to save money.

02. What is the topic sentence?

B. When trying to save money, you need to know about your options.

Explanation:

The items that we can use as main ideas are the ones that are complete sentences, and that makes sense on its own. That is to say, that they do not need extra information so that the reader can understand what the sentence is telling.

In the activity number 2, the topic is ways to save money because it describes the different strategies to save money such as saving accounts, money market accounts, or certificates of deposit.

The topic sentence is option B because it is the one that summarises what the text is saying. The paragraph mentions the other options as ways that a person can have to save money.
