Let’s solve each one:

---

Part 1: Write the root word

1. unhappy → happy
*(“un-” is a prefix meaning “not,” so root is “happy”)*

2. anger → anger
*(This is already a root word; no prefix/suffix added)*

3. thinking → think
*(“-ing” is a suffix; root is “think”)*

4. played → play
*(“-ed” is a suffix indicating past tense; root is “play”)*

5. replay → play
*(“re-” is a prefix meaning “again”; root is “play”)*

6. hopeful → hope
*(“-ful” is a suffix meaning “full of”; root is “hope”)*

7. teacher → teach
*(“-er” is a suffix indicating person who does something; root is “teach”)*

8. helpful → help
*(“-ful” is a suffix; root is “help”)*

9. speaking → speak
*(“-ing” is a suffix; root is “speak”)*

10. bigger → big
*(“-er” is a suffix for comparison; root is “big”)*

Part 2: Multiple Choice Questions

11. Find the word that has a PREFIX.
A. crash — no prefix
B. play — no prefix
C. replay — “re-” is a prefix (meaning “again”) ✔
D. repair — “re-” is a prefix ✔
But both C and D have prefixes. However, if only one answer is allowed, both are correct. Since “replay” and “repair” both start with “re-”, but the question asks for “the” word, likely expecting one. Both are valid, but let’s see context.
Best choice: C. replay or D. repair — both correct. But if only one option, D. repair might be more common in teaching contexts.
However, C. replay is clearly correct. Let's go with C. replay ✔

Wait — actually, both C and D have prefixes. But since it's multiple choice with single answer, perhaps the intended answer is C. replay, as “re-” is clearly visible.

But let’s look at the options again:
- replay → re + play → prefix ✔
- repair → re + pair → prefix ✔
So both are correct. But if we must pick one, either C or D is acceptable. Likely C. replay is expected here.

Answer: C. replay ✔

12. Find the word that has a SUFFIX.
A. hope — root word
B. hopeful — “-ful” is a suffix ✔
C. thought — root word (past tense of think)
D. thoughtful — “-ful” is a suffix ✔
Again, B and D both have suffixes. But the question says “the word.”
Between B and D, B. hopeful is simpler and more direct.
But D. thoughtful also has “-ful.”
However, hopeful is clearly formed with suffix “-ful”.
Answer: B. hopeful ✔
*(Alternatively, D could be argued, but B is likely the intended answer.)*

Actually, both B and D have suffixes. But since it's a single-choice question, and hopeful is simpler, B. hopeful is best.

✔ Answer: B. hopeful

13. What does *replay* mean?
A. Play again ✔
B. Not play
C. Play only
D. Play now
“Re-” means “again,” so “replay” = play again.
✔ Answer: A. Play again

14. What does *unhappy* mean?
A. Care again
B. Happy again
C. Not happy ✔
D. Full of joy
“Un-” means “not,” so “unhappy” = not happy.
✔ Answer: C. Not happy

15. Which word has a PREFIX?
A. Cakes — no prefix
B. Unfair — “un-” is a prefix ✔
C. Playing — “-ing” is a suffix
D. Helped — “-ed” is a suffix
✔ Answer: B. Unfair

16. Find the word that has a SUFFIX.
A. Sing — root
B. Singing — “-ing” is a suffix ✔
C. Song — root
D. Singer — “-er” is a suffix ✔
Again, both B and D have suffixes. But B. singing is more straightforward.
However, D. singer has “-er” (suffix), which is a common suffix for people.
But the question asks for “a suffix,” and both are valid.
If only one answer, B. singing is often taught first.
✔ Answer: B. singing or D. singer — but likely B. singing is expected.

But let’s check: “singing” has “-ing” (present participle), and “singer” has “-er” (person). Both are suffixes.

However, B. singing is simpler.
✔ Answer: B. singing

17. What does *happen* mean?
A. Happened in the past
B. Happening now
C. Happens again
D. Happen again
The word happen is present tense, meaning “to occur.”
So “happening now” is closest to its meaning.
✔ Answer: B. Happening now

18. What does *fearless* mean?
A. Fear again
B. Without fear ✔
C. Full of fear
D. Full of love
“Less” means “without,” so “fearless” = without fear.
✔ Answer: B. Without fear

🔍 Explanation Summary:

- Prefixes are added at the beginning of a word (e.g., *un-* in *unhappy*, *re-* in *replay*).
- Suffixes are added at the end (e.g., *-ful* in *hopeful*, *-er* in *teacher*, *-ing* in *playing*).
- Root words are the base forms from which other words are built.
- Understanding prefixes and suffixes helps determine word meanings.
