Jon did an excellent job. But he is too smart that after he read the stimulus, he can always find a right way to stab the question right into the heart. I could not follow him. I feel more comfortable with JY's explaination. He lower this level to a mundane moron and explain from a moron's perspective. LOL.
Now this question is crystal clear to me. Thank you, JY.
Well I've finished all of the 7sage curriculum and started PT 6 days ago. I've been doing one PT a day, and thanks for my job, I had pretty much time at work to BR.
But disappointedly and scary is that my PT plateau kept unchange around 154. Usually I got about 90% on LG, 60% on LR, which sometimes the passages and too rocket science to me to apply memory method. And 70% on LR. Recent PTs showed I am pretty confident for those questions with 3-star difficulty or less. But those hard questions are still huge challenging time-consuming monster to me. I will take my entire next week off and will fully devote my self to PT.
Any suggetions? Thanks.
What if C is only a few people know how to produce white glass back then?
Sorry I can probably understand why D is correct and why E is wrong. But I did not really get the idea of control group. Why did half of the people in shorter experiement get placebo make this experiment as a good one?
