#20 - Global, Must Be True, Minimum

[Administrator]

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=6641)

The correct answer choice is (A)

To minimize the number of times W plays a T, focus on Template #2, which has no immediate assignment of W to a T (Template #1 already has W playing a T fourth). Next, attempt to minimize the number of times W performs a T in Template #1.

First, can both the second and third solos (both T) be played by Z? Yes:

Next, from the fourth rule, because Z plays the second solo, W must play the fifth solo. Can the fifth solo then not be a T? Yes, it can be an M:

The hypothetical above conforms to all of the rules, and because W does not play a T at any point, the correct answer is zero. Thus, answer choice (A) is correct.

Hello… Hopefully someone can help me understand the setup to be able to see things quicker and arrive to the correct answers and the majority of the questions for the last game on the June 2012 LSAT game questions 19-23; The more I try to get the correct answers I just don’t understand how they arrive to those answers…. (Hopefully my questions and explanations do not confuse anyone)

Option 1:
W w/z w/z Z
M T T M __
1 2 3 4 5

Option 2:
W z/w z/w W
M _ T T __
1 2 3 4 5



Question 20- Why would the minimum be zero when there is the possibility of having
W
T in placement 4 based the stated rules?


***I hope I have made sense, please get back to when possible, and most importantly out of this game, is I would really like to know how you would set it up on the first time to be able to see all inferences and move through the game quickly.

THANKS!!!

Hi Karla,

Again, this is about the question stem. The stem isn't trying to ascertain if it is possible for W to play a traditional piece, but how many traditional pieces he has to play. So, while W can play a traditional piece as stated in the third rule, it is possible that W never plays a traditional piece, and hence the answer is zero.

I will note that in both 19 and 20 you had the understanding of what was occurring (at least I think so); it was the way the question was worded that tripped you up. That's an easily correctable thing, so that's a good sign

Please let me know if that helps. Thanks!
