"if ...to be a hedge, that hedge must be of either H or L"
there's no "but not both", therefore, is there in total three options?
hedge--> H / L / H + L
the issue of purely "either...or..." and "either...or...but not both" always bothers me.
Could any one plesae help confirm whether the diagram above correct?
Thanks in advance!
Well don't let it bother you! When somebody states, "Either A or B"...That totally gives us the right to have both.
The "or" in LSAT use is not disjunctive, it is always inclusive of both possibilities being listed.
The only time it does not is when you are directly told "not both."
Either A or B
Translation: Has to be at least one of A and B, could be both.
Either A or B but not both
Translation: One must selected, the other must not be selected.
Either A or B and not both
Translation: And/But are logical equivalents on the LSAT, so this is the same statement as above.
In this scenario (#5) we are given
If hedge ---> Hem or Ley
The stimulus gives us information that directly tells us that both types could not be used. So the possibility of both is gone.
We now have: If hedge ---> Hem
This is because we know that Ley is out of contention as we read from the stimulus.
