To complete the sentences with the correct quantifiers (MANY, MUCH, A LOT OF, LOTS OF), it's important to understand the context and whether the noun is countable or uncountable.

- "Days" is a countable noun, so "many" is appropriate here.

- "Times" is a countable noun, so "many" fits best.
Don’t try to do too many things at once.
- "Things" is countable, so "many" is the right choice.

- Here "much" is used because it refers to an unspecified amount of food, which is uncountable.

- "Rain" is an uncountable noun, so "a lot of" is suitable.

- "Work" is uncountable, so "a lot of" works well.

- "Much" is appropriate here because it refers to an unspecified, uncountable amount of tasks.

- "Time" is uncountable, so "a lot of" is appropriate.

- "Books" is countable, so both "lots of" and "a lot of" are correct, but "lots of" gives a slightly more informal tone.
Jane has a lot of friends at school.
- "Friends" is countable, so "a lot of" is suitable. "Lots of" could also work if you prefer a more informal style.
In summary, "many" is used with countable nouns, "much" with uncountable nouns, and "a lot of" or "lots of" can generally be used with both but tend to make the sentence slightly more informal.
