Question

which is best to do with sentence 7 (reproduced below)? environmental chemist mike murray claims, \as invasive species like zebra mussels overwhelm the great lakes, large stretches of the lakes have become underwater deserts.\ leave it as it is. add information in parentheses explaining murrays claim. paraphrase murrays comment rather than quote it directly. provide murrays credentials as a scientist. add a citation indicating the source of the quotation from murray.

Explanation:

In academic writing, when using a direct quote, it is important to provide a citation indicating the source. This gives proper credit to the author and allows readers to verify the information. The other options are not as necessary. Leaving it as is without a citation is incomplete. Adding information in parentheses explaining the claim might be redundant if the context is clear. Paraphrasing might lose the impact of the direct quote. Providing credentials again (since he is already identified as an environmental chemist) is not essential.

Answer:

Add a citation indicating the source of the quotation from Murray.
