Answer: The answer for this is the first one (the boy got separated from his mom)
Explanation: The first one is the answer because if the boy ran away from his mom, he would be feeling an emotion like happiness, or even fear or anger, but he isn't feeling any of those things, he's upset, and most of the time when a kid gets separated from a parent, they tend to get upset because they are in an unfimilar enviorment, and kids, especually young ones, tend to cling onto their parents. It isn't the third one because if the mom was calling the boy, he wouldn't be crying and would go straight to her. Plus if she was calling him, then it would say so in the paragraph. It isn't the last one either because if the boy had never been to an amusement park, he would be feeling curious, or fear.
