Answer:
6. Active
7. Passive
8. Passive
9. Active
10. Active
11. Passive
Explanation:
When a sentence is "active", it means that the author is describing something as is, for example, "Larry tossed the clothes". When it's passive, the author describes something that was done and then tells who did it, for example, "the salad was improved by adding yellow peppers". This sentence could be active by simply saying, "Larry added yellow peppers to improve the salad".
So, basically, it's just switching around the words in the sentence to mix up the sentence structure. Hope I didn't confuse you too much!
