Let’s go through each sentence one by one. We need to add either
“un” or
“dis” in front of the bold word to make a new word that makes sense in the sentence.
Remember:
- “Un” usually means “not” — like *unhappy* = not happy.
- “Dis” often means “opposite” or “remove” — like *disconnect* = break the connection.
Now let’s solve each:
