1. What is the verb tense and how is it differnet then passé composé?
    The imperfect ( l'imparfait) expresses or describes continued, repeated, habitual actions or incomplete actions, situations, or events in the past. The imperfect describes what was going on at an indefinite time in the past or what used to happen. The imperfect can be translated by “would” when it implies “used to.” The imperfect is a simple tense that does not require a helping verb.             example:Imperfect: An ongoing action with no specified completion. You use the passé compose when your talking about an action that had a certain start time and an end time.

Je visitais des monuments - I was visiting monuments

Passe Compose: One or more events or actions that began and ended in the past
Je suis allé en France - I went to France

2. When do you use it vs when you should use passé composé
The imparfait is used to talk about three types of situations, what someone was doing, what someone used to do and conditions( time, weather, emotions etc.) passé composé is used to express actions that started and ended at a specific time in the past.
