Explanation:

• Question 2: Words with prefixes are "untidy" (prefix "un-"), "disobey" (prefix "dis-"), "impossible" (prefix "im-"), "return" (prefix "re-").
• Question 3: Words with suffixes are "slower" (suffix "-er"), "brownish" (suffix "-ish"), "strangest" (suffix "-est"), "teacher" (suffix "-er").
• Question 4:
• "Misplaced" is correct as "mis-" is a valid prefix meaning wrong. "Unplaced" is not a standard word in this context.
• "Uncertain" is correct as it is a standard word. "Certainless" is not a proper word.
• "Joyful" is correct as it is a standard adjective. "Joyness" is not a proper word.
• "Washable" is correct as it is a standard adjective. "Nonwash" is not a proper word.
• Question 5: The prefix "trans-" means "across".
• Question 6: "Uncertain" means not sure.
• Question 7: "Dishonest" means not honest, which fits the context of the cashier not giving enough money back.
• Question 8: "Grateful" means feeling or showing thanks, which fits Jonathan's behavior of thanking the judges.
