I would say the correct answer is girls had laughed a little nervously.
Based on this clause, we can deduce something about their personality, and that is that they are happy kids who want to laugh all the time but they are not allowed to. The other options are either direct characterization or not characterization at all.
Answer:
is that a question is it C
a carrot, a biscuit, a potato, a bagel, a bean, an apple
some cereal, some garlic, some cheese, some honey, some bread, some rice
Tedious means repetitive, tiresome, boring, brain-numbing.
I think that the best choice is the last option, I hope this helps! : )
