Answer :
Based on the information provided in the problem:
- Bertie went to the mountains.
- Cara went to an island.
- Alice went to the desert.
We can deduce that the scuba diver among the three is Cara. Why? Because scuba diving is typically associated with activities near the sea or ocean, which aligns with Cara going to an island for vacation. So, the logical conclusion would be:
B. Cara is the diver.
This conclusion is based on the fact that scuba diving is usually done in aquatic environments, making it more likely for the person who went to an island to be the scuba diver.
