May someone give your answer soon, you know why I said it in the answers, big man!
You use one by kind of like end of sentences but they are pausing. I think that's how you use them.
Answer:
B
Explanation:
First you can eliminate D because is shows nothing about whether the trip was fun.
While C shows they enjoyed the time, it could be 'what they needed' because it was relaxing or just an escape from reality. Not because it was incredibly fun.
A and B both show he most likely enjoyed the trip, but B is better because A still leaves room for questions. While in B you know that they enjoyed the trip because its directly said it was "the best trip ever", A he could be smiling because he's happy to see his dad or something else. B gives the most direct answer to the question.
The correct answer is c. Details of setting and characters' Appearance.
