#### Part 1: Write the plural form of the following nouns

We need to convert each singular noun into its plural form. Here are the rules for forming plurals in English:
- Most nouns add -s (e.g., cat → cats).
- Nouns ending in -s, -sh, -ch, -x add -es (e.g., box → boxes).
- Nouns ending in -y (preceded by a consonant) change -y to -ies (e.g., library → libraries).
- Some nouns have irregular plural forms (e.g., mouse → mice, child → children).

Let's solve each one:

| Singular Noun | Plural Form |
|---------------|-------------|
| library | libraries |
| bird | birds |
| person | people |
| class | classes |
| key | keys |
| child | children |
| moose | moose |
| box | boxes |
| ox | oxen |
| mouse | mice |
| knife | knives |
| woman | women |
| bison | bison |
| rat | rats |

#### Part 2: Correct the sentences

We need to check if the underlined words in the sentences are in their correct plural forms. If not, we will correct them.

1. I see two deers.
- The word "deers" is incorrect. The plural form of "deer" is deer (it remains the same).
- Correct sentence: I see two deer.

2. The kittens are sleeping.
- The word "kittens" is already in its correct plural form.
- Correct sentence: The kittens are sleeping.

3. Danny saved ten gooses.
- The word "gooses" is incorrect. The plural form of "goose" is geese.
- Correct sentence: Danny saved ten geese.
