I got a 164 in Sept 2025 and 162 for August 2026. Planning to take Sept in a couple weeks. Should I cancel the 162?
So this means that the some scientists' claim that superheated plasma in which electrical resistance fails is a factor in causing so called ball lightning would be false?
I chose D.
Evidence I used to support D: "Important theoretical obstacles to living on raw food in the wild today include both the low digestibility of much raw plant food.."
My thought process: Because there is strontium in the bones, which comes from the plants, that means that there had to be an adaptation for it to digest and go into the bones because if they didn't have the adaptation, they wouldn't have been able to digest it otherwise. Since the passage says raw plant food is hardly digestible, if they did have plant remains in their bones, that means they did digest it. Which means they had to have an adaption for them to be able to digest it. Cause how else did it end up in their bones? This weakens the assumption, regardless of the plants were cooked or not.
What am I missing? Only thing I can see is that these are 'theoretical obstacles'... maybe it is possible to digest raw plant food and therefore end up in your bones even without adaption.
The explanation says, "The author’s thinking that if we detect methane in the Martian atmosphere, then it must not have been hit by UV radiation yet. Otherwise, we wouldn’t be able to detect it." Can you explain how we deduce this? Why can't it be the case that we can detect it only after it has been hit by UV radiation?
