Question

we(go)shopping last weekend there(be) a great crowd at the shopping center

Answer 1

The correct answer is - 'went' and 'was'.

It is very obvious that the given statement is in past tense since the sentence talks about a situation that happened 'last weekend'.

So, the past tense of 'go' is 'went' and for 'be', it is 'was'.

So, the corrected statement will be - We 'went' shopping last weekend. There 'was' a great crowd at the shopping center.

Answer 2

Given sentence is
We(go)shopping last weekend there(be) a great crowd at the shopping center.

Here, we have to tell the correct form of verb that should be used in the above sentence.

So, the sentence with the correct form of verb would be:

We (went) shopping last weekend, there (was) a great crowd at the shopping center.
