Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=11436)

The correct answer choice is (C)

This is a challenging Global question. Both answer choice (A) and answer choice (E) can be eliminated because M and G can never be in the same group of five ranked products (see the discussion of the last rule above). Answer choices (B) and (D) have an identical structure: they each play on relationships created by combining the second rule with the fourth or fifth rule. For answer choice (B), as discussed above, when H is selected for testing then F must rank first. For answer choice (D), also as discussed above, when K is selected for testing then G must rank first. Hence, both answer choice (B) and answer choice (D) can be eliminated because each is impossible. By process of elimination, answer choice (C) is correct.

Hi P.S.,
This was a difficult question for me as I narrowed down between Answer choice B and C.

Is it correct to infer that ONLY F or G could be 1st (I didn't recognize the 2 Solution Sets of having either F or G 1st only). I had some trouble understanding this rule because I understood that other variables could go 1st. For example, in answering Question #7 I tested answer choice C. I came up with Solution set in this order: I, L, K, F/H, H/F (G and M are out). Is it incorrect to say that I COULD go 1st?

I tested answer choice B and because I didn't see any rules broken, I chose it. My solution was in order of: M, L, H, F/I, I/F (G and K are out). Why is this incorrect? Can someone please explain

The rule that "Either F or G ranks first" means that those are the only variables that can be ranked first, GGIBA003@FIU.EDU. If other variables could be ranked first while those variables went elsewhere, the rule would be meaningless. Thus, every solution to the game must start with F or else with G, and never with any other variable.

I have a follow up question: Is it correct to imply that any rule with EITHER and OR (such as "Either F or G ranks first") means ONLY? This means that ONLY F or G can be first. I think because I misinterpreted the rule it costed me points on this game.

GGIBA003,

No, it's not necessary that every "either/or" mean "only", but this is a one-to-one linear game, where five things are tested, each being ranked 1 to 5 with no ties. That means that, in the scenario, it already sets up that only one thing will be ranked 1st (and only 1 ranked 2nd, and...etc.). If F or G is first, then, to fulfill that rule, one of them has to be first. There won't be room for anything else to be first.

In short, the scenario sets up that only one thing will be first, and the rule we're talking about determines that that single thing is F or G. If one of them is first, nothing else can be, because of the scenario.
