Context: At first , I spent whole days with him , showing him around , driving him to local sights and antique malls , but starting yesterday , I really needed to attend to personal business , so I left him pretty much on his own , as I will today . I am not sure how long he is staying , but life must go on . The weather has been fantastic these last several days , but as often happens to me when the weather is nice , I can develop some severe sinus headaches . It is a curious contradiction , and very frustrating . I just took something that should help , and now I am going for a long walk to the bank to deposit some checks .

Question: Why might they have been showing them around ?
Options:
0. Because the weather is nice
1. None of the above choices .
2. Because they are visiting and want to see the local sights
3. Because they have sinus headaches
Answer: 2
