These are taken from MGMAT SC guide: 
1) The travelling salesman was dismayed to learn that neither his sons nor his daughter were interested in moving. 
2) I was so thirsty that either of the two drinks were fine with me 
 Is "sons nor his daughter " subject in Qn 1 and is "Either of the drinks" subject in Qn. 2? 
Thanks a lot.
