The correct answers are During and Outside of
Explanation:
Prepositions are usually short words placed after nouns to show the way different parts of a sentence relate including objects, time, location or people. Common prepositions in English include words such as across, outside, over, between, until, from, to, in, after, on, before, during, among others whose main function in sentences is to express location or other grammatical relations. Considering this, in the sentence "During the game, the basketball rolled outside of the boundary line" there are two prepositions the first one is "During" that expresses a time relation in the sentence by showing when the actions described took place "the basketball rolled outside of the boundary line" and "Outside of" which is considered as a compound preposition, because it contains more than one word and that expresses location, by stating where the basketball rolled.
