Read the rule and choose the correct options

We can use the past continuous to talk about repeated background events in the past. It can suggest that the situation was temporary or subject to change.

We only use the past continuous for repeated background events. If they are repeated main events, we use the past simple:

I phoned you four times last night. Where were you?

NOT: I was phoning you four times last night.

We don't use the past continuous in the same way as used to when we talk about things in the past which are no longer true:

We used to go on holiday to Yorkshire every year when I was little.

NOT: We were going on holiday every year when I was little.
