I am unclear about what Choice A means on the LSAT.
When it says general principles, could it be something like "People invest in the stock market to make money" or "Stock prices reflect the value of the company".
But what is a particular example?
I felt that Passage A gave examples of people selling stocks but to be a particular example does it have to be a specific example like "People invested in Facebook during its IPO because people all thought it was going to be profitable" or "Bank X was engaged in insider infomation and as a result harmed the stock price of Company Y but that actually helped millions of every-day investors who would have other-wise purchased Company Y's share at a premium".
In other words, does a particular example on the LSAT need to be a specific example and not general examples like "Millions of investors could have lost billions had the inflated stock price been allowed to continue "
For Choice B, it does describe A in that A's reasoning was trying to say insider trading isn't all that radical; in fact it is just like every day trading and even better. On the other hand, Passage B does not try to draw any similarities between controversial and uncontroversial activities; instead its reasoning structure is closer to Here is what happens when we have insider-infomation and here is an immediate consequence (lack of transparency+trust) and, in turn, here is the bigger consequence ( bad capital markets)
