If a star has an apparent magnitude of 7.5, would you be able to see it with the aid of a 15-cm telescope?

I don'y quite understand what the question is here. What it is saying is that you should write a professional email, probably in MLA format, to a politician (Mayor, school board, President, etc...) about an issue that affects a large amount of people. This can be civil rights, education, climate change, poverty, etc...
