premise: Charlie Catlett (born 1960) is a Senior Computer Scientist at Argonne National Laboratory and a Senior Fellow in the Computation Institute, a joint institute of Argonne National Laboratory and The University of Chicago, and a Senior Fellow at the University of Chicago's Harris School of Public Policy.
hypothesis: Charlie Catlett has two vowels in his last name.
reason: The vowels "a" and "e" are the only ones in Catlett - Charlie's last name. The system probably doesn't get that just because a statement is irrelevant does not mean it isn't definitely correct.
