Another way to ask a question is by placing est-ce que at the beginning of a declarative sentence.
Tu manges des bonbons. = You are eating some candies.
Est-ce que tu manges des bonbons? = Are you eating some candies?
Elle mange des bonbons = She is eating some candies.
Est-ce qu’elle mange des bonbons? = Is she eating some candies?
Notice that que forms a contraction when it precedes a word starting with a vowel.
