Final answer:
The complaint about soda cans probably related to them being stored in a way that caused them to burst due to increased pressure from the release of dissolved gas when heated.
Step-by-step explanation:
The motel reviewer's complaint about the soda cans can be inferred from the given information, suggesting that the issue was related to the fact that carbonated water releases dissolved gas when heated. This causes an increase in pressure, and if a soda can is subjected to this kind of condition, it could potentially burst. In the context of a motel review, the complaint could stem from the cans being stored improperly, perhaps in a heated environment, which could cause them to explode, posing a risk to guests and maintenance alike.
