Le passé composé, l'imparfait et le plus-que parfait

Understanding these 3 verb tenses is not easy. Is the activity completed or on-going? Had it already been done?

Read the statement(s) which includes the past tense, the imperfect, or both. Then answer the question about the statement(s). Be sure to read carefully to determine the BEST answer--- yes, no, one can't know, or it's possible--- based on the information provided.

FR 12: When you have successfully completed the activity, re-write the ambiguous statements with more information or in a different verb tense so that the question has a definite yes or no answer. Check your sentences with a classmate or your teacher.
