Fill in the blank with the most suitable word:
Option A is the right answer because, in a dispute, a fair-minded person would play the role of a mediator and try to resolve the issue. So ‘mediate’ is the correct word.
Option B is incorrect because ‘interrupt’ means ‘to stop someone while they are saying something or to break the continuity.’ A 'fair-minded' person would not 'interrupt' a dispute, but would resolve it.
Option C is incorrect because ‘intercept’ means ‘to stop and prevent from continuing’. Although it could be used to mean that the person is 'stopping the dispute', it is not the best option to use with the phrase 'a fair-minded person'.
Option D is incorrect because ‘moderate’ means ‘to preside over’ (eg. discussions or meetings). We do not normally use the word 'moderate' for disputes.
