for the question 1, does using "someone" not differ from using "one"? I thought the final chain made weak sense because "someone" already implies 'some others' who can still use force lightning without negative emotions.

Instead of using sufficiency but necessity, maybe "only unless" not "unless", would this make both options correct?

Since the LSAT is digital now, I believe we cannot draw this on a separate piece of paper while taking an exam. Then, where do we write Lawgic while taking the digital LSAT?
