How do you know whether to use 'qui' or 'que'?

The easiest way to remember which of these pronouns to use is by learning the following simple rule: 'qui' comes before a verb, whereas 'que' comes before a subject noun or pronoun. For example, in the sentence 'le film qui est amusant', 'qui' is used instead of 'que' because it is followed by the verb 'est'. Compare this to the sentence, 'le film, que je trouve amusant'. In this case, 'que' is used because it is followed by the pronoun 'je'.
Practice with the following sentences:'La pomme .... je vais manger plus tard''Les filles .... sont jolies''Le garçon .... tu vois tous les jours'
