Focusing on this one key step is helping me pick the right answer on PSAs, especially on questions like this one: Look for the answer choice that reflects the direction in which the action in the stimulus flows.

Could somebody please explain how PSA questions are different than sufficient assumption/follows logically questions?

In case anybody finds this useful, here's how I personally used lawgic to get to the right answer:

Step 1: /ICT → /RH+

Step 2: /RH+ → /FPR

Step 3: /ICT → /RH+ → /FPR

Answer = /ICT → /FPR or FPR → IC

In other words: If the city hadn't invested in computer modelling technology, then we know its financial predicament was not resolved.

For anyone who is having a hard time grasping this: Just because something is B, doesn’t meant mean it’s A. In other words: Meeting the necessary condition doesn’t tell us whether something also = sufficient condition

For all the folks who are having a hard time grasping this flaw, I've found it helpful to think about it in these terms: "Just because something isn't A, doesn't mean it can't be B." That's it.

Here's how I did mapped this out in a fairly simple way, in case anyone finds it helpful.

Here’s the rule:

- X → A

- /X → B

-Therefore: /B → A

This means that we're looking for the answer choice that says: If it's not A, then it's B

Looking at the answer choices, it becomes clear that the rule is LW → L or /LW → NC. Which means that we're looking for the answer choice that says: /NC → L.

In other words, if a university class is not in a normal classroom then it will be in a lab. This matches the correct answer.
