Here are the correct forms of the words to complete the sentences. I have checked each one based on the grammar rules for singular and plural nouns.
1.
women
(The word "three" tells us there is more than one, so we use the irregular plural of *woman*.)
2.
feet
(The verb "are" shows it is plural. The irregular plural of *foot* is *feet*.)
3.
mice
("A lot of" means many. The irregular plural of *mouse* is *mice*.)
4.
apples
(This is a regular noun, so we just add an 's'.)
5.
boxes
(Words ending in 'x' usually take 'es' to become plural.)
6.
children
(The number "ten" means plural. The irregular plural of *child* is *children*.)
7.
fish
(The verb "aren't" is plural. The plural of *fish* stays the same: *fish*.)
8.
pens
(Regular plural: add an 's'.)
9.
butterflies
(For words ending in a consonant + 'y', change the 'y' to 'i' and add 'es'.)
10.
dresses
(Words ending in 'ss' take 'es' to become plural.)
11.
cherries
(Change the 'y' to 'i' and add 'es'.)
12.
pencils
(Regular plural: add an 's'.)
13.
teeth
(The verb "are" shows it is plural. The irregular plural of *tooth* is *teeth*.)
14.
books
(The word "these" indicates plural. Regular plural: add an 's'.)
15.
sheep
(The number "twenty" means plural. The plural of *sheep* stays the same: *sheep*.)
