Context: Not brilliant , and I was aiming for 500 , but I ' m not going to berate myself for managing to complete my first proper bout of writing in months . At 6 pm I wanted to continue , but was feeling faint and in need of food after such a long stint of largely uninterrupted mental concentration . That 's typical of me : to get so immersed in something that I forget to eat .
Question: What may be the reason I got so immersed in my writing ?
Option 0: None of the above choices .
Option 1: I had not written in a long time and it felt good to start again .
Option 2: I did n't want to get up because I thought I might lose my place .
Option 3: I was n't paying attention to the time because I was so hungry .
Answer: 1
