Again, I'm NOT trying to play the devil's advocate, but general knowledge does play into how safe you are when flying RC.
Clouds
The types of cloud are useful for getting a general idea of weather conditions, helping you judge when safe flying windows are.
Icing conditions
Don't fly when there's freezing rain. Be aware that moving your aircraft from warm areas to cool areas MAY introduce condensation that can then inhibit control surfaces. (De-icing solutions may be as simple as a toothpick).
Alcohol consumption.
In practice, I don't even think about operating a vehicle within two hours of my last drink. Same would apply to my planes (but seriously, if you're drinking, the flying day's already done, no?).
Disclaimer, though. I do agree that for our purposes, those questions are very loosely connected to our hobby. They're more general knowledge questions that will tell the Government wether or not the applicant is aware of the "dangers" affecting and caused by a >25kg blob flying in the air.
If, and only if I was taking the gov. test, I'd cheese it by reviewing the regulations for full-size aircraft (what those questions seem to be taken from). According to the people who designed the regulation, an RC craft poses the same property/personal damage risk of an ultralight (which they couldn't possibly, but, paranoia is a thing). All of the "flight classes" they link to are for drones that they themselves define as advanced operations craft. So it follows that they'd assume that operating a RAS is a perfectly uniform experience regardless of size over 250g. They are obviously wrong, but for the sake of argument, that is what the exam is based around.
(Disclaimer, again. I've not actually seen the exam because I've decided to get a MAAC membership in the new year and meet up with my local flight club, thus bypassing the need to put my name down on the "criminals with drones" list. I am simply replying with regard to what I am gathering is a rudely generalized assumption that we, RC flyers, are twits who don't have the common sense to respect people's belongings and personal safety. I don't know a single person who ever said "let's go out tonight in this thunderstorm after a few drinks and crash my beautiful (insert aircraft) into this person's window/face just for kicks.")
