Question

if you are unsure about whether or not to include a citation because you have seen that information somewhere before,
a. it means the information is not important enough to cite c. you should consider it common knowledge
b. you should include a citation anyway d. you should leave it out of your paper
please select the best answer from the choices provided

Explanation:

When in doubt about citing information, it's better to err on the side of caution and include a citation. This avoids potential plagiarism issues. Option a is incorrect as importance isn't the main factor here. Option c - just because you've seen it before doesn't make it common knowledge (common knowledge is widely - known, like historical events with broad consensus). Option d is wrong as leaving it out might mean omitting relevant information.

Answer:

B. You should include a citation anyway
