Law School Discussion

The conclusion does imply that this practice is wrong, but the key is to focus on what it explicitly states. According to the speaker, "this practice greatly increases the health risk to U.S. consumers." In support of this statement, the speaker notes that the same pesticides are used on imported agricultural products. However, if other countries are manufacturing and exporting the same pesticides, how can we be sure that the imported products contain pesticides that were manufactured here?

It's easy to miss the additional condition towards the end of this question. Your hypothetical doesn't break any of the rules, but G must be the second one off the van for number twenty-two.

For game #2, first get a handle on the conditions:
#1: P_U; ~O_N
#2: P_N and P_U --> S_N and S_U; ~S_N or ~S_U --> ~P_N or ~P_U (contrapositive)
#3: J_N and J_U --> ~R_N and ~R_U; R_N or R_U --> ~J_N or ~J_U (contrapositive)
#4: ~J_N and ~J_U --> P_N; ~P_N --> J_N or J_U (contrapositive)
#5: R_N or R_U --> ~S_N and ~S_U; S_N or S_U --> ~R_N and ~R_U (contrapositive)

A couple of the conditions can be simplified:
J_N and J_U <--|--> R (#3)
R <--|--> S (#5)

Combining the first two conditions, we know that if P_N is on sale, then S_N and S_U are on sale. We can also link the fourth condition into the equation:
~J_N and ~J_U --> P_N --> S_N and S_U

Here are explanations for a couple of the questions:
10. Starting with the first condition given in choice D, due to the fourth rule, new pop must be on sale. Since both types of pop are on sale, both types of soul must be on sale (second rule), which contradicts the second condition given in answer choice D.

11. From the fourth rule, we know that new pop is on sale. Since used pop is on sale (first rule), the second rule is triggered, and both types of soul must be on sale. Since rap and soul cannot both be on sale (fifth rule), we know that rap is not on sale. Thus, we can eliminate B, C, D, and E, and A is left as the correct answer. We cannot infer anything about used opera.

Here's a diagram for the fourth game:
PrepTest 31, Game 4

Preptest 25, June 1998, Section 2, LR 21:
UP_F = unpopular with the faculty
UP_S = unpopular with the students
MP = modify the policy
NP = adopt a new policy

We can diagram this question as follows:
Premise 1: UP_F --> MP
Premise 2: UP_S --> NP
Premise 3: UP_F --> UP_S; UP_S --> UP_F

(E) UP_F --> UP_S --> NP
This is essentially P3 + P2.

Since we're looking for a point of disagreement, strong wording doesn't necessarily rule out an answer choice.

(B) Dana would disagree with this based on her first sentence. Pat would agree with this. Since flexibility in working alone or with others is "invaluable" (stimulus), all children "should" (choice B) learn to adapt to different methods.

(E) Dana would agree with this. Pat might also agree with this. In saying "not always," he or she leaves open the possibility that it is sometimes desirable. If E stated that it is "always desirable," then Pat would disagree.
