Leo: Given the sentence "A young boy stretches up to touch an airplane propeller." is it true that "Small boy tries to grasp a propeller on a plane at a museum."?
Mei: OK, So, let's think first...

A boy can touch something without having to grasp it. Planes are located in other places besides at a museum.
Thus, the answer is it is not possible to tell.
