If a person comes up with two answers to the question: what’s more important to know a person? And his friends asked: well, I'm not sure one necessarily precludes the other.

“Preclude” as a verb in the dictionary has two meanings:

1. to prevent the presence, existence, or occurrence of; make impossible

2. to exclude or debar from something

But in this case, it’s kind of hard for me, an ESL, to grasp its meaning.

Could you explain a little if you have time?

Thanks
