题目：The information passed on by word of mouth is important because____.
A. it is better than that found through any other source
B. it helps you find some of the best housing never advertised
C. the final year students always offer better information
D. the landlords have little valuable information
喵查答案：B
解析：推理判断题。在“Word of mouth”部分寻找答案。口传的信息很重要是因为“is never advertised ；It might be that you can find out about good offers from final year students.”但是也有弊端，分析四个选项，只有B是正确的。
