Why do we need "Te" here?
It is there for emphasis only. It is optional.
"Eszed ezeket?" - Are you eating these?
"TE eszed ezeket?" - Are YOU eating these?
"Te ESZED ezeket?" - Are you (really) EATING these?" (ew)
"Te ESZED EZEKET??" - Are you really eating THESE???" Ewwwwww!
We don't; they just haven't added the versions without te as correct yet.
