Help the excited traveler pack their bags for a big vacation! Choose ALL the sentences that use "one" or "ones" correctly.
The correct answers are: My suitcase is broken, so I need to buy a new one. Don't pack the dirty shirts; only pack the clean ones.
One correctly replaces the singular noun suitcase, and ones correctly replaces the plural noun shirts.
You cannot use "one" to replace an uncountable noun like water.
"The lighter ones" is incorrect for replacing the singular noun jacket (it should be "the lighter one").
