1 Section 2 - Analytical Reasoning Questions 1-6 We can infer properly that K and N cannot occur on Wednesday and that Q cannot occur on Friday. 1) Type of Question: Global List This question should be approached using a rule sweep. a) This answer is eliminated by indented rule #3 because Quilting occurs after Kite-making. b) This is the correct answer because every other answer is eliminated using a rule sweep. Additionally, this answer does not appear to break any of the given rules. c) This answer is eliminated by indented rule #3 because Quilting occurs on the same day as Needlepoint. d) This answer is eliminated by indented rule #2 because Rug-making is in the Morning. e) This answer is eliminated by indented rule #1 because Jewelry is in the Afternoon. 2) Type of Question: Global Cannot be true We are looking to eliminate all given answers which could occur on Thursday morning. For efficiency, the hypothetical given in Question 1 is used as a starting point: Morning J K S Afternoon Q N R The answer choices are eliminated in the following order: B,C,E,A a) Building on the hypothetical established in D, we find that this answer can be eliminated because S and R can switch places with J and Q without breaking any rules: Morning S J K Afternoon R Q N b) The answer to Question 1 provides a hypothetical which eliminates this answer. c) This answer can be eliminated because N and K can switch places in the hypothetical without breaking any rules: Morning J N S Afternoon Q K R

2 d) This is the correct answer. All others are eliminated and it does not seem to break any rules. e) This answer can be eliminated because S and R can switch places with K and N in the hypothetical without breaking any rules Morning J S K Afternoon Q R N 3) Type of Question: Global Cannot be true We are looking to eliminate all given answers which could occur on Wednesday morning and Afternoon, as provided. The answer choices are eliminated in the following order: B,E,D,C a) This is the correct answer since all others have been eliminated. b) This answer can be eliminated by the hypothetical obtained in 2)e). c) Building on the hypothetical generated in D, we can see that S and Q can switch places without breaking any rules. Therefore, we can eliminate this answer: Morning Q J N Afternoon S K R d) Placing S and Q in the morning creates this hypothetical: Morning S J N Afternoon Q K R Since this hypothetical does not break any rules, we can eliminate this answer. e) This answer can be eliminated by the hypothetical obtained in Question 1. 4) Type of Question: Local Could be true The local rule places K on Friday morning. A hypothetical sweep reveals that we can use the following hypothetical from 2)a) as a starting point: Morning S J K Afternoon R Q N

3 a) This is the correct answer because it conforms to the hypothetical from 2)a) shown above. There is no need to continue. 5) Type of Question: Local Cannot be true We are looking to eliminate all given answers which could occur on Thursday. The local rule places Q in the morning and an initial inference shows that Q cannot be on a Friday. A hypothetical sweep reveals that 3)c) is the only hypothetical which can be used as a starting point: Morning Q J N Afternoon S K R a) This answer is eliminated by the initial hypothetical. b) This answer is eliminated by the initial hypothetical. c) Building on the initial hypothetical, we see that we can switch J and K with N and R without breaking any rules: Morning Q N J Afternoon S R K This eliminates this answer. d) This answer is eliminated by the hypothetical obtained in C. e) This is the correct answer since all others have been eliminated. 6) Type of Question: Global How many could be? A hypothetical sweep reveals that J, S sand Q can all occur on Wednesday morning. We know additionally that R can only occur in the afternoon. As well, we know from our initial inferences, that K and N cannot occur on Wednesday. Therefore, the answer is 3 (choice C). Questions 7-12 We can infer properly that neither H nor J appear first nor second. L, M and P do not appear last; combining this inference with indented rule #4 we find that only H and J can appear last. We also find that L M and P cannot occur 5 th. 7) Type of Question: Global List This question should be approached using a rule sweep.

4 a) This answer is eliminated by indented rule #2 because P appears after J. b) This answer is eliminated by indented rule #3 because G appears before H even though M appears before P. c) This answer is eliminated by our initial inference and indented rule #1 because H appears first. d) This answer is eliminated by indented rule #4 because G appears last. e) This is the correct answer because every other answer is eliminated using a rule sweep. 8) Type of Question: Global Cannot be true We are looking to eliminate all given answers which could occur. For efficiency, the hypothetical given in Question 7 is used as a starting point: P M L J G H a) This answer can be eliminated because from the initial hypothetical, we see that H and J and be switched without breaking any rules: P M L H G J b) This answer can be eliminated by the initial hypothetical. c) This is the correct answer. All others are eliminated and it does not seem to break any rules. d) This answer can be eliminated by the initial hypothetical. e) Building from on the initial hypothetical, we can switch M and P. However, indented rule #4 would require that H precede G. Since G cannot be placed sixth, J takes its place: M P L H G J 9) Type of Question: Global How many could be? From our initial inferences, we see only H and J can appear 6 th. The answer is two: D. 10) Type of Question: Local Could be true The local rule places J before M. A hypothetical sweep does not reveal any possible starting points, and so we must construct our own.

5 a) Since we know that J cannot be first, we can test the possibility of G in first place. G L P J M H This does not break any rules so we know that this is the correct answer. b) This is eliminated by indented rule #1 because H appears before L. c) Since L and P must appear before J, we see that P must be fixed for the fourth place for this answer to work. However, according to the local condition, we find that J must be placed before M. This would leave M in the last place which violates one of our initial inferences. d) This answer is eliminated because J cannot occur last and neither can G. e) This answer is eliminated because J cannot occur last and neither can G. 11) Type of Question: Local Must be true We are looking to find eliminate answers which could be false with the local rule in place. The local rule places L immediately before G. A hypothetical sweep does not reveal any possible starting points; however, we see that in 10)a) L and G can be switched without breaking any rules, so we use this as a starting point: L G P J M H a) Building on the initial hypothetical, we can attempt to place Geyer in 4 th place without breaking any rules: P M L G H J This hypothetical eliminates this answer and should raise suspicious over answer C. b) Building on the initial hypothetical and initial inferences, we can place J in the last place: L G P M H J Since this does not break any rules, we can eliminate this answer. c) This answer should immediately appear suspicious. If G follows L immediately and are hypothetically placed in the 4 th and 5 th positions respectively, we realize that J and H must come after L; with G in the 5 th place, we see that this cannot occur. This is the correct answer. d) This is eliminated by the initial hypothetical. e) This is eliminated by the initial hypothetical. 12) Type of Question: Local Must be true

6 We are looking to find eliminate answers which could be false with the local rule in place. The local rule places M first. A hypothetical sweep reveals 8)e) as a possible starting point: M P L H G J a) This is eliminated by the initial hypothetical. b) This is eliminated by the initial hypothetical. c) This is the correct answer. All others have been eliminated. d) This is eliminated by the initial hypothetical. e) This is eliminated by the initial hypothetical. Questions 13-17! will represent a cleaning 13) Type of Question: Global Could be true A hypothetical must be developed, since must start without one. For efficiency, we will attempt to use the most plausible one given the constraint that only three cleanings are allowed. This appears to be answer E which puts all three mulches together. S S S!M M M! S 7 We see then that answer E is correct. 14) Type of Question: Global Must be true We are looking to eliminate answers that could be false with the local rule in place. a) We note that the hypothetical obtained in question 13 does not eliminate any answers. We construct one below to eliminate answer A: M M! S!M! S S S 7 b) We construct another hypothetical to eliminate this answer: M! S S!M M! S S 7 c) This answer is eliminated by the hypothetical in A.

7 d) This is the correct answer because every other answer has been eliminated. e) This answer is eliminated by the hypothetical in B. 15) Type of Question: Local Must be true We are looking to eliminate answers that could be false with the local rule in place. The local rule places M in the third place. A hypothetical sweep does not reveal any possible starting points, and so we must construct our own: S S!M M M! S S 7 a) This is eliminated by the initial hypothetical. b) This is eliminated by the initial hypothetical. c) This is eliminated by the initial hypothetical. d) This is eliminated by the initial hypothetical. e) This is the correct answer. All others have been eliminated. 16) Type of Question: Local Must be true We are looking to eliminate answers that could be false with the local rule in place. The local rule allows only two cleanings. A hypothetical sweep reveals that the hypotheticals from question 13 and 15 are appropriate: S S S!M M M! S 7 S S!M M M! S S 7 a) This is the correct answer. All others have been eliminated. b) This is eliminated by the hypothetical from question 13. c) This is eliminated by the hypothetical from question 15. d) This is eliminated by the hypothetical from question 15. e) This is eliminated by the hypothetical from question ) Type of Question: Local Could be true

8 The local rule allows no more of than two loads of the same material to be hauled consecutively. A hypothetical sweep finds no appropriate hypotheticals A hypothetical sweep finds that 14)b) is appropriate, but does not apply to any of the answer choices. Therefore, we must construct our own hypothetical: M M! S S!M! S S 7 Answer choice B follows this hypothetical and is the correct answer. Questions ) Type of Question: Global List This question should be approached using a rule sweep. a) This is the correct answer because every other answer is eliminated using a rule sweep. Additionally, this answer does not appear to break any of the given rules. b) This answer is eliminated by indented rule #1 because G and L must share the same training. c) This answer is eliminated by indented rule #1 because either F or K must be a photography assistant. d) This answer is eliminated by indented rule #3 because H must be a photograph assistant. e) This answer is eliminated by indented rule #5 because K is assigned to S. 19) Type of Question: Local Must be true We are looking to find eliminate answers which could be false with the local rule in place. A sweep finds that the hypothetical given in Question 18 can be used as a starting point; a possible combination for the writers assistants can be filled in: Photographer F H J Writer L/G G/L K a) The hypothetical eliminates this answer. b) This is the correct answer because every other answer has been eliminated. Additionally, it is supported by the hypothetical. c) Building on the initial hypothetical, we can eliminate this answer because we see that Kanze does not have to be assigned to Tuscany: Photographer F H J Writer K G/L L/G

9 d) The common factor strategy dictates that we should test D and E first. Indeed, the hypothetical eliminates this answer. e) The common factor strategy dictates that we should test D and E first. Indeed, the hypothetical eliminates this answer. 20) Type of Question: Local Could be true The local rule assigns F and H to the same story. We can infer that H will be a photographer s assistant and F will be a writer s assistant. A hypothetical sweep does not reveal any possible starting points, and so we must construct our own. Photographer K H J Writer G/L F L/G We see then that B is the correct answer. 21) Type of Question: Local Could be true The local rule assigns F as a writer s assistant. A hypothetical sweep reveals that the hypothetical used in question 18 can be applied here: Photographer K H J Writer G/L F L/G We see then that D is the correct answer. 22) Type of Question: Local Could be true The local rule assigns G and K to the same story. A hypothetical sweep reveals that the hypothetical used in question 18 can be applied here: Photographer K H J Writer G F L

10 Going through the answer choices, we see that E is the most similar to the hypothetical. The correct answer is E because F and L can switch places without breaking any rules: Photographer K H J Writer G L F 23) Type of Question: Global Cannot be true We are looking to eliminate all the interns who could be assigned to Tuscany. a) This answer is eliminated by the hypothetical in question 22. b) This answer is eliminated by the hypothetical in 19)c). c) This is the correct answer because every other answer is eliminated using a hypothetical sweep. d) This answer is eliminated by the hypothetical in question 19. e) This answer is eliminated by the hypothetical in 19)c).
