8. (B) Question Type: Unconditional (Orientation)
Tackle one constraint at a time with this sort of question. The first constraint eliminates (C), at which point we should stop evaluating answer choices with that constraint and move on to the next one. Using the second constraint, we’re forced to look for remaining answer choices in which Rini receives L. In (D), Rini does receive a letter, but does not receive a postcard as is required. Eliminate it.
The final constraint eliminates (E). At this point, we could review the remaining choices using the constraints a second time (perhaps, we might think, we moved on from using one constraint prematurely as the LSAT does occasionally rely on one constraint to rule out more than one answer choice in an orientation question), but this strategy proves fruitless. Instead, we need to take a step back and look at the game’s basic set-up. Indeed, we can eliminate (A) based on the fact that not all of the elements are distributed in that scenario, violating a fundamental rule of the game.
