Fill in the blank in the given sentence so that it makes sense. We run the…

Concept: In a paired-synonym fill-in-the-blank, the missing words must not only fit the sentence individually -- together they must share one consistent connotation and reinforce the sentence's overall logical direction. Read the sentence's larger claim first (what is being argued), then pick the pair of words whose shared meaning matches that claim; a pair that mixes two different emotional registers (for example anxiety and blandness) breaks the internal consistency even if each word alone seems plausible.

Application: The sentence warns that we risk turning issues of identity and autonomy into divisive matters that create a wedge between people and regions. That warning only makes sense if the issues are first being cast as unimportant or overused -- 'mundane' (ordinary, unremarkable) and 'hackneyed' (overused, trite) share exactly that connotation: both frame the issues as commonplace and dismissible, which is the trivialization the sentence needs before the risk of magnifying them into division can even arise. So the pair 'mundane, hackneyed' completes the sentence coherently.

Cross-check -- why the other pairs break register:

• 'tiresome' + 'hackneyed': 'tiresome' expresses annoyance/fatigue with dealing with something, while 'hackneyed' expresses staleness of an idea -- a complaint about effort mixed with a complaint about overuse, so the pair doesn't share one consistent connotation.

• 'uneasy' + 'mundane': 'uneasy' conveys anxiety, the opposite register of 'mundane', which conveys blandness -- pairing worry with ordinariness produces an internally inconsistent description.

• 'tiresome' + 'uneasy': both describe an emotional reaction (fatigue, anxiety) rather than characterizing the issues as commonplace or overused, so this pair misses the sentence's trivializing sense entirely.
