Can you give me the link to the story please? I'll see what I can do from there.
A search engine is a program that searches/identify items in a database which corresponds to keywords specified by the user. A meta search engine is an online information retrieval tool that uses data of a web (search English) and that makes its own results. A subject directory is a service which offers a collection of links to the internet which is posted by creators. Hope this helped!
The statement which best describes the mistake the writer makes in the paragraph is the following one:
The writer loses focus and shifts to another topic.
He starts off by pointing out the overall benefits of exercising, and supports his idea by also giving examples of activities people should engage in. However, focus is lost when the writer begins to address the importance of a balanced diet to the body. That would require a new paragraph.
One of the answers that could fit in the blank is better.
Hope this clarifies your doubt.
That, I believe, would be dialect.
Example: (I parked the car)
Boston: I paakked tha kaaa!
Britain: I pocked the coh.
New York: I pawked the caw.
