lot of) sweets. 4. There are (many, much, a lot of) trees in the park. 5. How (much, many, a lot of) coffee do you

4. There are a lot of trees in the park.

In this sentence, «a lot of» is the most appropriate choice.

We use «a lot of» to express a large quantity or number of something. In this case, we are talking about the quantity of trees in the park, so «a lot of» is the correct phrase to use.

5. How much coffee do you drink in a day?

In this sentence, «much» is the most appropriate choice.

We use «much» when we are asking about the quantity of something that is uncountable. Coffee is an uncountable noun, so we use «much» instead of «many».

For example, we say «How much water do you drink?» or «How much sugar do you take?», not «How many water do you drink?» or «How many sugar do you take?»

Therefore, the correct sentence is «How much coffee do you drink in a day?»
