Answer:
1. pets
2. boxes
3. dishes
4. glasses
6. lunches
Step-by-step explanation:
When there is a plural of a word, it means there is multiple of it. We can write a plural with a s at the end, however when you write a plural, interpret it to make sure it makes sense.
For example, dishs does not look right or make sense, so we can add an es, instead of an s.
