Completely off topic but the way 7sage breaks down sentences in the stimulus would be so helpful for learning languages and knowing how each part of a sentence modifies the meaning

I liked this video a lot, specifically her clear explanations and annotations of the questions + the notes

@DamianoVigneri I think of the "all" indicator as placing one circle inside the other. In order for everyone who is 21+ to be able to purchase alcohol, the 21+ circle must be inside the 'can purchase alcohol' circle. It doesn't work in reverse. If the 21+ is the superset, then only a subset of this population would be in the 'can purchase alcohol' bubble.

@rayanessafi It's my understanding that the Geologist's claim is "the scientists' challenge to the dominant view is refuted by the presence in petroleum of biomarkers."

geologist view: petroleum is formed from the fossilized remains of pants and animals (which would produce biomarkers)

scientist view: petroleum is formed from deep carbon deposits

The best way to weaken the geologist's argument is to find a source of biomarkers that is not fossils. Strains of bacteria deep in the Earth's crust is a plausible alternative explanation as to why biomarkers could be found in petroleum

@DestinyBoyles My understanding was that you have two rules, and Kumar arriving 17 minutes after the last ring falls outside the scope of those. I think of it like a language your computer can't process.

You know if that if someone was marked late, than they arrived 5+ minutes after the homeroom bell. You also know that if someone did not arrive 5+ minutes after the homeroom bell, than they were not marked late.

However, you were not given a rule for interpreting what happens when 5+ min late is the sufficient condition, so you have no information to make an inference. It's like your code throwing an error
