Greg does n't work in our clinic , but he works directly with it . He stops by every day , making his rounds , and often he and I chat . One day , a couple of months ago , Greg told me that " a group of people from work " were stopping off for drinks , and he invited me to join them .

Question: Why did Greg invite the narrator out to drinks after work ?
Answer: None of the above choices .He invited her out because he was interested in dating her .He wanted an opportunity to talk to her about work .He took the initiative to invite everyone directly to the event .
