thank you for explaining this so well, ALEKS did a horrible job at explaining.

For some questions on Aleke, I got it wrong when I chose the number with no + or - as the most precise. Is there an explanation for that?

Pretty sure this is wrong, for B they are not saying it is +/- 0.0. In the real world there is no such thing as a measurement with perfect precision, we are limited by the tools at our disposal. By saying it is 6.7kg the team is saying their instrument was capable of measuring to the tenth place but was uncertain beyond that. Without being able to check my answer I would wager that C is actually the most precise measurement since 6.7 actually indicates +/- 0.1.
