Premise: There were not many driveable roads, however, so the Ranas' new Rolls-Royces were brought to Kathmandu in pieces, either on frames carried by big teams of porters or on the ropeway, a lift that carried freight from Hetauda in the Terai over the Mahabharat range.

Hypothesis: The roads going to Kathmandu were splendid, making the driving of Rolls-Royces there quite simple.
Relation: contradiction
