b. circle the words that are real words. cross out the ones that are not real words.
nonsense review reanswer overdeliver disarm
inappropriate unmask impossible outlive reactivate
nonallowed mislike resweep unactive misinformed

Explanation:

• For part A, we need to add the prefixes un-, pre-, or over- to the base words. For example, unhappy (prefix un- + base word happy) means not happy.
• For part B, we check if the words are real. Nonsense means meaningless words. Review is a real word meaning to look at again. Reanswer is not a standard word. Overdeliver is a real word meaning to deliver more than expected. Disarm means to remove weapons. Inappropriate means not suitable. Unmask means to remove a mask. Impossible means not possible. Outlive means to live longer than. Reactivate means to make active again. Nonallowed is not a standard word. Mislike is not a common word. Resweep is not a standard word. Unactive is not a standard word (the correct form is inactive). Misinformed means given wrong information.

Answer:

Part A

1. overactive (assuming a typo in the problem as overactive imagination makes sense if we consider the context of having a lot of activity in imagination. If we strictly follow the given prefixes and base words, maybe it's a mistake in the problem setup. But if we assume over- is for active in a sense of excessive), 2. unlock, 3. overheat, 4. unhappy, 5. test (assuming it's pre - test if we consider the context of a spelling test that comes before something, but the problem says add prefixes from the given ones. If we assume it's just using the base word as is, but that's odd. Maybe a problem error. But following the instruction of adding prefixes: if we assume pre - test), 6. previews, 7. overcharged, 8. unanswered, 9. preschool, 10. unacceptable

Part B

Circle: nonsense, review, overdeliver, disarm, inappropriate, unmask, impossible, outlive, reactivate, misinformed; Cross out: reanswer, nonallowed, mislike, resweep, unactive
