I'll work through this negative prefixes exercise step by step, matching each word with the appropriate negative prefix and completing the sentences.
Let me analyze each sentence and determine which negative prefix (un-, im-, in-, il-, ir-, dis-, non-) should be used:
Working through each sentence:
1. "My brother didn't behave properly and he didn't have any punishment. It's __________"
- Base word: proper → improper (but we need a noun form)
- Looking at the words available: POLITE → IMPOLITE doesn't fit here
- Actually looking at context: "didn't behave properly" = IMPROPER behavior
- But the blank needs to complete "It's ___"
- Wait, let me reconsider - could be related to FAIR → UNFAIR
2. "It's a very good plan. The only __________ is that we haven't got enough money."
- ADVANTAGE → DISADVANTAGE ✓
3. "Our future is always __________. You can never know what is going to happen."
- CERTAIN → UNCERTAIN ✓
4. "That man cannot read or write. He's an __________ person."
- LITERATE → ILLITERATE ✓
5. "Susan wants quick answers for everything. She can't wait. She's really __________"
- PATIENT → IMPATIENT ✓
6. "He always behaves as if he were 7 years old and he's 18! He's very __________"
- MATURE → IMMATURE ✓
7. "I hate getting up early every morning. I really __________ that."
- LIKE → DISLIKE ✓
8. "They haven't got a job at the moment. They've been __________ for a year now."
- EMPLOYED → UNEMPLOYED ✓
9. "-Would you like a cigarette? -No, thanks, I'm a __________"
- SMOKER → NON-SMOKER ✓
10. "Sometimes John studies hard, sometimes he doesn't. He's a very __________ student."
- REGULAR → IRREGULAR ✓
11. "Jenny never wears smart clothes. She always wears __________ clothes."
- FORMAL → INFORMAL ✓
12. "It would have been really __________ to leave the party without saying goodbye."
- POLITE → IMPOLITE ✓
13. "Lots of __________ immigrants crossed the border last night. They didn't have any documents."
- LEGAL → ILLEGAL ✓
14. "He always lies to all his classmates and steals things from them. We never trust him because he's a very __________ boy."
- HONEST → DISHONEST ✓
15. "I've never seen such an __________ mother. She leaves the kids alone for hours."
- RESPONSIBLE → IRRESPONSIBLE ✓
16. "This information is not very important. In fact, it's __________"
- RELEVANT → IRRELEVANT ✓
17. "The students are organising a __________ demonstration against the war in Iraq."
- VIOLENT → NON-VIOLENT ✓
18. "They were going on holiday but an __________ accident made them come back home immediately."
- FORTUNATE → UNFORTUNATE ✓
19. "I don't think they'll win. I think it's quite __________"
- PROBABLE → IMPROBABLE ✓
20. "The magician drank the mixture to make himself __________ but it didn't work."
- VISIBLE → INVISIBLE ✓
21. "The sun was shining but suddenly it __________ behind a cloud."
- APPEARED → DISAPPEARED ✓
22. "Are you superstitious? Well, you know it's __________ to walk under a ladder."

23. "Your answer is not sensible at all. It's completely __________"
- LOGICAL → ILLOGICAL ✓
24. "India became __________ from Britain in 1947."
- DEPENDENT → INDEPENDENT ✓
Now let me verify sentence 1 again:
"My brother didn't behave properly and he didn't have any punishment. It's __________"
- This seems incomplete. Looking at the pattern, it might be "UNFAIR" (from FAIR)
Let me check all the words provided and ensure I've used them correctly:
