In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.

Rationale: When sugar is added to coffee, it not only becomes sweet but also 'fattening' due to the extra calories added. The term 'fattening' specifically refers to the potential weight gain associated with consuming sugary drinks. Choices B, C, and D do not accurately describe the impact of adding sugar to coffee.

Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established.

Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.
