ok, I found the passage.
The question asks:
In lines 17-19, the author's description of the customs police suggests that the author views them with
It's not A, D, or E, because the girl does not think the officers are good at their job, she says "Still, the officials weren't clever enough, or suspicious enough, to check my sister and me" no where does it imply that she was afraid of the police officers.
She did not doubt the police officers either, because they had in fact searched her parents. So it's not B.
She does however, show signs of disrespecting them, because she says that "lucky for us, since we are both carrying some silverware we were not allowed to take out of Poland in large pockets sewn onto our skirts especially for this purpose, and hidden under capacious sweaters" which again goes back to them not being "clever enough." Also, the fact that the police officers caused her parents to be "highly agitated," could have caused her to disrepsect them, thus making the answer C.
You can't assume that she'll be afraid or proceed with caution simply because she is hiding something from the officers, you have to go by what the passage says.
I hope that helps.
