My understanding was both Mark Knophler and Axl Rose were doing the same thing, writing a song from a dumbass bigots perspective, it’s just that people hate Axl and automatically ascribe the worst motives (despite a literal black man playing guitar on that GNR track).
Traditionally is done by heating, separating and the introduction of rennet, which is an enzyme from calf guts that converts milk into a solid form that a herbivore can digest. This relates to why cows milk kills human infants and kittens but they can survive on goats. Cheese basically dates from ancient times when everyone was lactose intolerant but some farmer noticed how calves digest milk.
That’s easy enough to answer, but he really should work on his grammar. In that case you just do 3 groups of three, weigh two of them. If they’re even, the third group is different. Weigh 2 membres of the third group, they’ll either be even or one heavier. Weight the last member against the heavier one from step 2 to see if they’re even or not for your answer.
That’s not the question. Either the scales balance, and the third is heavier or lighter, or the scales don’t balance and you get both answers, but the question is purposely framed this way
