To weaken the sale's manager's argument: The company opened 5 more new restaurants last year than the year before.

Yes. Unless the rule states that either P or L, but not both. P and L can both be selected.

I would target accuracy in timed sections first. For example, in LR try to get 18/21 or 20/23 and guess on the rest. Having a mindset that for the most part, LSAT is really a test of how well you manage your time for each question, helped me to score higher.
