Context: Monday is my busiest day , though it was made slightly less busy yesterday as pleasingly the second lecture of the day , the boring Cities and Settlements , was cancelled . Medieval Europe was really interesting as usual , looking at the Iron Age long house and how it changed as societies developed . I had lunch in the park with Alan ( we were absolutely freezing though ) . Then I worked on my essay for a bit before the Cicero class which was intimidating and not particularly useful as usual .

Question: Why did the writer have lunch in the park with Alan ?
Options:
0. Because the writer looked at the iron age long house .
1. Because Monday is the writer 's busiest day .
2. None of the above choices .
3. Because Medieval Europe was really interesting .
Answer: 2
