I understand the explanation for the question and the diagramming that led to the answer. However, I still am confused with the first line of the stimulus: "Because of the recent transformation of the market". Using the lesson on for/since/because being followed by a premise, that was my assumption and how I attempted the problem the first time around.
None of the explanations use that first sentence at all though. They just use
/10% --> B
and
10% --> 20%
Why is the because in line 1 not used as per the for/since/because lesson?
I suggest not seeking affirmation from the test/studying. It is a long journey with pitfalls along the way. LSAT studying related affirmation/reward is too unreliable - there is no guarantee of the time frame upon which you will improve/get the score you want, etc. Seek affirmation and reward in other parts of your life. Things like hobbies, friends, and relationships are a much more reliable stream of affirmation and reward, which in turn will help you with your LSAT studying.
Secondly, my non-mainstream view of depression is that it is not a disease, but a symptom telling you that your body needs something. It could be anything. Exercise, socializing (every type that in sum scratches your itch), sunlight, etc.
Also, perhaps this just means the methods you were trying aren't working for you and that you need to try another method? Have you exhausted every single resource/test prep company out there?
