Let’s go step by step to solve each sentence using the correct word from the word bank.
The prefixes
un- and
dis- both mean “not” or “the opposite of.” So we’re looking for words that fit the meaning of each sentence.
Word Bank:
- dislikes
- unfinished
- disappointed
- unfair
- disagreed
- disapproves
- unacceptable
- unbelievable
- unpaid
- disinfects
---
Sentence 1:
> After school, the teacher ________ the classroom by wiping the tables with cleaner.
We need a verb that means cleaning or making safe from germs.
→ “disinfects” fits perfectly — it means to clean something to kill germs.
✔ Answer:
disinfects
---
Sentence 2:
> Tio’s parents were ________ with the low grades on his report card.
Parents would feel sad or let down by bad grades.
→ “disappointed” is the right emotion here.
✔ Answer:
disappointed
---
Sentence 3:
> The teacher asked her students to complete any ________ work.
This means work that was started but not finished.
→ “unfinished” is the obvious choice.
✔ Answer:
unfinished
---
Sentence 4:
> The story my brother told about the giant fish he caught was ________, so we thought he was lying.
If you think someone is lying, you probably don’t believe them.
→ “unbelievable” means hard to believe — perfect fit.
✔ Answer:
unbelievable
---
Sentence 5:
> My mother ________ of playing video games all the time.
This means she doesn’t approve or likes it.
→ “disapproves” means she thinks it’s not good.
✔ Answer:
disapproves
*(Note: “dislikes” could also seem possible, but “disapproves of” is a common phrase when talking about behavior or habits. Also, “dislikes” would usually be followed directly by the thing disliked — e.g., “My mother dislikes playing...” — but here it says “of playing,” which matches “disapproves of.”)*
---
Sentence 6:
> Sarah ________ the taste of cough medicine, but she knows it will...
She doesn’t like the taste — that’s normal!
→ “dislikes” fits best here.
✔ Answer:
dislikes
*(Again, note: “disagreed” wouldn’t make sense — you don’t disagree with a taste. “Unpaid”? No. “Disinfects”? No. So “dislikes” is correct.)*
---
Now let’s double-check all answers against the word bank to make sure we didn’t reuse any word (unless allowed — but in this case, each blank should use a different word).
Used so far:
1. disinfects
✔
2. disappointed
✔
3. unfinished
✔
4. unbelievable
✔
5. disapproves
✔
6. dislikes
✔
All are unique and from the word bank. Perfect.
Final Answer:
1. disinfects
2. disappointed
3. unfinished
4. unbelievable
5. disapproves
6. dislikes
