W: Sir, can I come in now?
女：先生,我现在可以进去了吗?
M: Sorry, Lady. I am afraid that you have to wait half an hour for our business hours that are from 8：30 am to 5:30 pm.
男：对不起,女士.恐怕你还要等半个小时才是我们的营业时间,营业时间从上午8：30到下午5：30.
When did the man arrive?
这个男士什么时间到的?
选A.
解析：营业时间是上午8：30.男士一到女士问可否进去,男士说还要等半个小时,说明男士提前到了30分钟,那男士就应该是8：00到的.
