3. (Julius) stopwatch clocked Mia at a record speed.

Wells's
Julius's

Joe is correct.

You could write 2 and 3 as Wells' and Julius', but the pronunciation is as Joe wrote them.

To write the possessive noun, you need to indicate ownership or a relationship between two things. In each sentence, you need to determine which word is the possessor and then add an apostrophe ('s) to form the possessive noun.

Let's break down the sentences:

1. (Water) three states are solid, liquid, and gas.
In this sentence, "water" is the possessor or owner of the three states. Therefore, we add an apostrophe and an "s" to form the possessive noun: Water's.

2. (Wells) novel The Time Machine is a classic.
In this sentence, "Wells" is the name of the author who wrote the novel. Therefore, we don't need to change the word itself; it is already possessive: Wells'.

3. (Julius) stopwatch clocked Mia at a record speed.
In this sentence, "Julius" is the possessor of the stopwatch. Therefore, we add an apostrophe and an "s": Julius's.

Remember, when forming possessive nouns, you should consider whether the noun is singular or plural, and then add an apostrophe or an apostrophe and an "s" accordingly.
