Read the excerpt from Barrio Boy by Ernesto Galarza. The Americans never drew an eagle on their flag. The red and the white were the same as on ours but why they liked blue better than green was just one of those peculiar things about Americans.

This excerpt is textual evidence that the author feels

lonely and homesick for his village and friends in Mexico.
curious and confused about an unfamiliar country.
scared and upset to be starting a new life.
scornful and embarrassed of his native homeland.

Ernesto most likely felt scared, questioning, and curious.

Scared: He wouldn't have examined it at first if he knew what it was, and most people are scared of new things

Questioning: As seen, he "examines it", which means he first questions it's usage

Curious: Ernesto wouldn't have experimented what it was, if he wasn't curious at first.

answer: c.   like someone who knows how to behave in public

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
