Q23

Hi so for this question is a could be false... I got R H K T S J as a possible ordering. So this order does not apply to this question since J can be highest correct? So I have to find a different order where J cannot be highest like R H K J S T? Thank you, Alex

The opposite of Could Be False = Must be True.

So four of these answers are unavoidable; they could not be otherwise.
One correct answer is optional; we could possibly find a counterexample.

We should start with the condition that R = 1,
see what other dominos fall into place,
and then pick an answer that discusses something that's still flexible.

If R = 1, then the last rule tells us that S = 5.

R _ _ _ S _

Rule 1 tells us that K is the accepted bid, and it must go 2nd or 3rd.
R ( _ K _ ) _ S _

If H has to be lower than J and K, then K can't be 2nd. It'll have to go H in 2, K in 3.
R H K _ S _

Who's left? J and T.

If J is 4, then it'll be
R H K J S T
if J is not 4, then it'll be
R H K T S J

We know that R must be 1, H must be 2, K must be 3, and S must be 5.
The only flexible ideas are whether J/T is 4/6 or 6/4. So the correct answer will deal with that last bit of remaining indeterminacy.

ANSWERS
A) Could be false. It's possible for J to be 6th, but it's also possible for J to be 4th.

B) Must be true
C) Must be true
D) Must be true
E) Must be true
