14. Who goes home by what? Alyosha, Borya, and Vitya study in the same class. One of them goes home from school by bus, another by tram, and the third by trolleybus. One day, after classes, Alyosha went to see his friend off to the bus stop. When a trolleybus passed by them, the third friend shouted from the window: "Borya, you forgot your notebook at school!" Who goes home by what?
14. Alyosha cannot ride either the bus or the trolleybus, therefore, he rides the tram. Borya does not ride the trolleybus, so he rides the bus. It leaves only the trolleybus for Vitya.
