Inanity

Explanation:

Inanity is one of the red flags you should look for when studying whether a source is credible. Inanity refers to a situation in which someone offers commentary that they are not qualified to write about. In this case, the people writing about life on Mars are not scientists, and Cooper should have noticed that. This would have indicated to him that the article was most likely not a credible source of information.

scholarship is an sc because, by definition, a subject complement is the adjective, noun or pronoun that follows a linking verb, for example the verb be (in any of its forms).
