Peer editing academic papers requires critical-thinking skills and diplomacy.
It is not a question, it is a statement. This sentence lacks some needed words for correct grammar. For example, if I change "requires" to "require" it indicates that academic papers require critical-thinking skills. "Peer editing academic papers require critical-thinking skills and diplomacy." The academic papers have become self-aware! Your sentence should read: "The peer editing of academic papers requires critical-thinking skills and diplomacy." now "of academic papers" becomes a descriptive phrase, describing "peer editing" "Peer editing requires critical-thinking skills and diplomacy." stands alone as a sentence. Descriptive phrases can be added to it. To make it a question, write this: "Does the peer editing of academic papers require critical-thinking skills and diplomacy?"
The subject of this sentence is not "academic papers" - it is "Peer editing". "Peer editing" is a noun clause; it is singular and therefore takes the third person singular form of the verb which is "requires".

It isn't - it's a subject-verb disagreement. The subject is singular ('peer-editing') but the verb is plural ('require'). It should be corrected thus: 'Peer-editing academic papers requires critical-thinking skills and diplomacy.' The error in the original sentence is to assume that the phrase 'academic papers' is the subject of the verb because it is next to it, and that therefore the verb needs to be plural. This is not the case. It is not 'academic papers' that require skill and diplomacy; it is the 'peer-editing' of those papers that requires those things.
