premise: New Hampshire Route 78 (abbreviated NH 78) is a 3.456 mi secondary state highway in Cheshire County in the southern part of the U.S. state of New Hampshire. A northward extension of Massachusetts Route 78, NH 78 runs entirely within the town of Winchester from the state border to downtown, where it ends at New Hampshire Route 10 and New Hampshire Route 119.
hypothesis: NH 78 is less than five miles long
reason: NH 78 is approximately 3.456 miles which is less than 5. The model probably got it wrong because it can't do inequality math.
