What do you guys think?

This article reminds me of questions I sometimes get on examinations. There will clearly be 2 correct answers, one no more-so than the other, but it's the examiner's rationale or lack of knowledge that renders only one choice accurate (at least to them). It's pretty frustrating.
As far as the title- I wouldn't necessarily say too much knowledge is 'dangerous'. Perhaps if utilized negatively...

i more we learn the less we know

Didnt read that, but yeah, in excess, useless 'facts', which are typically presented in a biased way, cloud your own opinions/morals

or the long version

Knowledge isnt dangerous, its the ignorant fucks who unwisely use knowledge for evil purposes such as power that are dangerous. If they only knew the most power could only be harnised by the most high...we are pawns in the game of existance no matter if we choose to think so or not.

I wish more people would have more knowledge.

That’s a terrible test. The question seems to be deliberately misleading or ignorantly proposed. It simply asks which one a GPS relies on to work. Not enough information was given in the question to make a decisive answer. To have only One correct answer would rely on giving the conditions to each scenario. But there are no conditions in the question. With no conditions given and without going into each scenario I find the only true answer is “All”.
