参考答案

正确答案：A
解析：W: Professor Nelson, could you please turn up the temperature here? I'm having a fever.
M: Yeah, I understand, but I don't control the thermostat. Tell you what, I'll talk to maintenance about it after class. In the mean time, I suggest you put on a sweater if you brought one.
Q: What does the mall imply?
选项中多次出现temperature, more clothes等词，又根据do anything, maintenance推断可能与调节温度有关。
综合理解题。女士请求男士调高温度，男士表示不能控制thermostat“恒温器”，他下课之后会找人修理，并建议女士如果带外套的话不妨穿上，可以看出男士暗示自己对此无能为力。
