We run the risk of magnifying these ............ issues of identity and…

To solve this sentence completion, consider the context: the sentence discusses magnifying certain issues into matters that create division. The missing word should describe issues that are common, overused, or unoriginal, which could be exaggerated into larger conflicts.

Option A (tiresome): This means annoying or tedious. While it could describe an issue, it doesn't imply that the issue is common or overused, so it doesn't fit the idea of being magnified into a larger problem.

Option B (uneasy): This describes a feeling of discomfort or anxiety. It is an emotional state, not a quality of the issues themselves, so it does not fit grammatically or semantically.

Option C (mundane): This means ordinary or commonplace. It fits well because mundane issues are often small and unimportant, but can be exaggerated into significant conflicts, which matches the context.

Option D (hackneyed): This means overused or clichéd. It also fits because hackneyed issues are frequently discussed and could be amplified into divisive matters.

Both 'mundane' and 'hackneyed' are strong candidates, but 'hackneyed' better captures the idea of overused, tired topics that are being exaggerated. Therefore, the best choice is D.
