1. What is the difference between a common noun and a proper noun?
A proper noun names a person, place or thing, and is always capitalized.
A common noun is only used for the people, places and things we see every day.
A proper noun can only be used in formal settings like school or work.
A common noun always follows a verb, a proper noun never does.
2.
Which of the following is the correct pluralization of the singular noun, baby?”
babes
baby’s
babies
babys
3.
Which of the following possessive nouns completes the following sentence? “The heartbreak showed on his face when he discovered his new bike had been stolen.”
boy’s
boys
boy
boys’

I'm pretty sure #1 is A. This is because a proper noun has a specific name for the object. For example, instead of "the boy" -- which is a common noun -- you'd use "John" or whatever name you want to put there.

#2 is C; when a noun ends in y, and you want to make it plural, you must replace the y with ies. The reason why it wouldn't be B is because adding 's makes it possessive, which means ownership. For example, "That baby's toy is so cute!"

#3 is A; this brings us back to #2, which is where I talked about possessive nouns. The sentence is saying that his heartbreak was showing. It implies that he is heartbroken, or the heartbreak belongs to him. (It sounds weird, but I'm sure you understand haha.)

Explanation:

So, to sum all of this up,

#1 is probably A because proper nouns have an exact name rather than a normal name such as "a building".

#2 is C because when nouns which end with y change into ies when plural.

#3 is A because the sentence implies possession of feeling heartbroken over something.
