Explanation:
We are given a worksheet about the prefix *un-*, which means “not” or “the opposite of.” For each sentence, we need to:
1. Find the word that starts with *un-* (that’s the word with the prefix).
2. Underline that whole word.
3. Write the base word (the part without *un-*) on the line.
Let’s go through each sentence one by one:
1.
We were unsure as to where to stand.
→ Word with *un-*: *unsure*
→ Base word: *sure*
2.
I wanted to uncover the truth.
→ *uncover*
→ Base word: *cover*
3.
I had to untie my shoes.
→ *untie*
→ Base word: *tie*
4.
The man decided to unload the truck.
→ *unload*
→ Base word: *load*
5.
My dad unplugged my video game.
→ *unplugged*
→ Base word: *plugged* (Note: *plug* is the root, but since the word is *unplugged*, the base word here is *plugged* — the worksheet uses the full base form as in the example: *unamused* → *amused*, not *amuse*. So we keep the same tense/ending.)
6.
I decided to unwrap my gift.
→ *unwrap*
→ Base word: *wrap*
7.
The janitor came to unlock the door.
→ *unlock*
→ Base word: *lock*
8.
The town had a lot of unrest.
→ *unrest*
→ Base word: *rest*
9.
Our team was undefeated last season.
→ *undefeated*
→ Base word: *defeated*
10.
The woman had unfinished business.
→ *unfinished*
→ Base word: *finished*
Double-checking: In the example, *unamused* → *amused*, so they keep the same form (past participle). So yes — *unplugged* → *plugged*, *undefeated* → *defeated*, *unfinished* → *finished* are correct.
Final Answer:
1. unsure — sure
2. uncover — cover
3. untie — tie
4. unload — load
5. unplugged — plugged
6. unwrap — wrap
7. unlock — lock
8. unrest — rest
9. undefeated — defeated
10. unfinished — finished
