Text: and so there's uh well i guess three or four different labs and they're all very nice uh computers all tied together on the LAN and one server that handles all the software so that the teachers don't have to go around to each machine and do their work they can control it from the machine the server it's it's a beautiful system but uh the only bad thing it seems to do is uh not the computer necessarily but the company the school system seems to put a little bit more pressure on the kids than uh than we had of course of course i guess with that learning comes that pressure
Entailment: Thanks to the LAN and a server which runs the software, the teachers can control their work.
Contradiction: Since the computers aren't connected, the teachers have to go from computer to computer to teach each student.
