Question

complete the text with the correct pair of words. how __ salt is safe to consume each day, and what __ does too much salt have on your health? much... effect many... affect many... effect much... affect

Explanation:

1. For the first blank: "salt" is an uncountable noun, so we use "much" (we use "many" with countable nouns).
2. For the second blank: We need a noun here to fit in the structure "what + noun + does...", "effect" is a noun meaning a change that results from an action or cause, while "affect" is a verb. So "effect" is correct. So the correct pair is "much... effect".

Answer:

much... effect
