Let’s solve this step by step.
We are given 10 root words and a word bank with three prefixes:
re,
un,
dis.
Our job is to pick the right prefix for each word so that it becomes a real, meaningful word — usually meaning the opposite or something repeated.
Let’s go one by one:
---
1. please → What happens if we add “dis”? → *displease* = to make someone unhappy. That works.
✔ Answer:
dis
2. able → Add “un” → *unable* = not able. Makes sense.
✔ Answer:
un
3. draw → Add “re” → *redraw* = to draw again. Perfect.
✔ Answer:
re
4. happy → Add “un” → *unhappy* = not happy. Classic example.
✔ Answer:
un
5. agree → Add “dis” → *disagree* = to not agree. Yes!
✔ Answer:
dis
6. usual → Add “un” → *unusual* = not usual. Common word.
✔ Answer:
un
7. tell → Add “re” → *retell* = to tell again. Like retelling a story.
✔ Answer:
re
8. equal → Add “un” → *unequal* = not equal. Used in math and life.
✔ Answer:
un
9. obey → Add “dis” → *disobey* = to not obey. Like breaking rules.
✔ Answer:
dis
10. write → Add “re” → *rewrite* = to write again. Very common.
✔ Answer:
re

Now let’s double-check we used only the prefixes from the word bank:
re,
un,
dis — yes, all good.
Also, check if any word could have more than one prefix? For example, “please” — can we say “replease”? No, that’s not a word. “unplease”? Also no. So “displease” is correct.
Same with others — each has one clear best fit.

Final Answer:
1. dis
2. un
3. re
4. un
5. dis
6. un
7. re
8. un
9. dis
10. re
