The correct answer is that the statement is too general for the speech.
Explanation:
The person who is in charge of giving the speech needs to narrow the purpose because it is too general. The stock market has a lot of stuff to talk about. So, it is better to make the purpose statement more specific.
The problem with this specific purpose statement for a classroom speech is that the statement is too general. We learn that the person who is giving the speech wants to talk to the audience about the stock market. However, this subject is too broad. The stock market has many different characteristics, elements and details that would need to be discussed in order to understand it. Moreover, these would be too complex to address in a single speech. Therefore, the purpose statement needs to be much more specific.
