You could also answer Ben & Jerry's with London and Rotterdam - I loved hearing their little-guy-beats-the-big-guys story at their ice cream factory in rural Vermont, but felt bummed when I heard they'd sold out to Unilevers, which sort of spoiled the story. Mind you, the "US State" prompt points us in one direction!
Doesn't the yin-yang symbol need to have the 2 dots inside the halves to actually be a yin yang? If it does, South Korea does not have them. I also thought it had to be in the same direction (split vertically rather than horizontally), and had to be black & white. The colour part I can see not mattering a lot, but I did think it had to meet specific criteria to actually be a yin-yang. I don't think the flag really meets any.
I looked it up, and it seems that colour and orientation don't matter, but every yin-yang symbol does have the dots. "One could not exist without the other, for each contains the essence of the other" It's the part about containing the other, which is where the opposite colour dots are important.
For the "lucre" question I tried profit, benefit, earnings, gains... I think all of them should be accepted, since this is the strict meaning of the Latin word "lucrum".
if it's in Italian then it should be terra / sole / luna.
if it's in Spanish, it should be tierra / sol / luna.
but currently it seems like it's just incoherent
I am definitely a fool for not noticing until this very moment. Fun quiz!
