premise: National Highway 26 (NH 26), (previously National Highway 43), is a National Highway in India, that connects Raipur in Chhattisgarh and passes through Odisha to connect with Natavalasa in Vizianagaram district of Andhra Pradesh. It connects National Highway 5 and National Highway 6 and transverses the Eastern Ghats.
hypothesis: National Highway 5 and 6 traverse the Eastern Ghats.
reason: The article only states highway 26 transverses the Eastern Ghats, it does not say if highway 5 or 6 do. The AI gets confused because of that statement being tacked on at the end  of the last sentence and automatically attributes it to the nouns in that sentence.
