I generally wake up early in the morning, and I am the type of person that is productive in the morning and as soon as i do something "unproductive" I don't easily get started again. My question is what do people do (outside of running and meditating) in between waking up and taking a prep test at 12 pm to stay focused? Would it be a good idea to read a somewhat easy to read book, or will that somewhat tire the brain out?
I'm probably overthinking this, but for answer choice D, if we apply the "negation test" it would state that the meteor melted from something other than the impact. I actually don't think thats necessary to the argument. It could have been the atmosphere that melted the rock and that would still give an accurate measurement of the polarity of Earth's magnetic field at the time, no? That would melt meteorites and it would be impossible for it to burn in the atmosphere for a considerable amount of time so it would have been right around the time of the impact. the only necessary assumptions concerning melting are that nothing melted it after, and that it was melted at the time it hit the earth. What actually melted it doesn't matter to the argument. If a fire breathing dragon walked up to the meteorite right after it hit the earth and melted it further and then the rock crystallization should still reflect the polarity of Earth's magnetic field at the time.
