Okay so in English I'm doing "Appositives"

I understand the question and I'm just confused a little.

Circle the appositives. Then, underline the noun each appositive explains.

1. Sheila, my cousin works in that department store.

I circled "Sheila"
I underlined "cousin"

Or is it the other way around?
Thanks!

It's the other way around.

The appositive is "my cousin."
It explains "Sheila."

Okay thank you.

So...

For

"I love to visit Pine Acers, our cabin in the mountains"

Circled "cabin"
Underlined "Pine Acres" ????

Yes.

The complete appositive phrase is "our cabin in the mountains."

Thanks again to everyone who helped me :)

You are welcome.

In the sentence "Sheila, my cousin works in that department store," Sheila is the appositive, and "my cousin" is the noun that Sheila explains.

To correctly circle the appositive and underline the noun it explains, you should circle "Sheila" and underline "my cousin." Therefore, you have identified the appositive and its corresponding noun correctly.
