Leo: Given the sentence "A person being blindfolded by a girl and a boy." is it true that "Two children blindfold ther father for a big surprise."?
Mei: OK, So, let's think first...
Me:
Just because its a girl and a boy does not mean the person being blindfolded is their father. Just because the person is being blindfolded does not mean it is for a surprise.
Thus, the answer is it is not possible to tell.
