A good scientist must have a keen mind an unqhenchable curiousity and a (groundless disinterested) desire to discover the truth

disinterested?

Ms.Sue you told me it should be maximum but groundless and disinterested are the only options. So is my answer still correct?

I don't see a scientist needs to be not interested in the truth.
It says disinterested means fair minded,free from selfish motives ;indifferent on my paper. What does that mean
OK. Using the first two definitions of disinterested, your answer is correct.
Okay, Thanks ! :D
You're welcome.

And thanks for being persistent in defending your answer! :-)
