premise: John Christian Hopkins (born 1960) is a Narragansett journalist, author, poet and public speaker who resides in Tuba City, Arizona, United States. After having grown up in Hope Valley, Rhode Island, Hopkins graduated from the University of Rhode Island with degrees in journalism and history in 1987.
hypothesis: John Christian Hopkins didn't go to school in 1988. 
reason: It said he got a degree in 1987, but didn't say whether or not he was going to school in 1988. A lot of people continue school after they get degrees because they are going for a masters or a higher degree. Or maybe he went to school for something else. Just because he graduated from one program in 1987 doesn't mean he didn't go to school at all the next year for an advanced degree. There just isn't any way to know.
