These rats were given the equivalent amount of caffeine that a person would consume with six cups of coffee every day. The caffeine increase also increased the occurrence of birth defects.

Answers and Explanations

1. D: John or Patricia. Of the four fastest-John, Bart, George, and Patricia-three are always chosen to start. If George is one as specified, that leaves John, Bart, and Patricia. Knowing George will only start if Bart also starts, if George is in the starting lineup, then Bart must also be. The other two fastest are John and Patricia; therefore, one of them is the third of the three out of the four fastest always chosen.

2. A: Erwin and Dexter. Bart must be starting because we know George is starting and will only start with Bart. Dexter and Bart will not start together, eliminating Dexter. Of the four fastest-John, Bart, George, and Patricia-we know Bart and George are starting; three of the four fastest are always chosen, leaving either John or Patricia, eliminating Erwin.

3. C: Marlene is starting and not among the four fastest, of whom three are always chosen; John and Bart-not just John (A)-are, leaving one more. Dexter is not one of the fastest, so it cannot be John and Dexter (B). Dexter and Bart never start together (D). John, Erwin, and Bart (E) are all three in the first group, from which only two are chosen. Of the fastest four, the choices here include only John and Bart.

4. E: Bart is the only one who must start in order for George (C) to start. If Bart does not start, then neither does George; but they are two of the four fastest players, of whom three are always chosen. If two of the four fastest didn't start, that would leave only two of the four fastest, not three.

5. B: Ben operates the Dragon; Paul operates Rex. Pam (NOT Dave) assists Sue, so they do not operate the Tiger, OR Melville; therefore, they operate the Gorilla, and Rex is the Kangaroo. Jill does NOT operate Hamish, so the Tiger she and Dave operate must be Melville. Therefore, Sue and Pam's Gorilla is Audrey; and Tom assists Ben with Hamish, the Dragon.

6. A: Dave is the assistant with the Tiger. Pam assists Sue with Audrey the Gorilla. By process of elimination, Gale assists Paul with Rex the Kangaroo, and Tom assists Ben with Hamish the Dragon, leaving Jill, who is assisted by Dave with the Tiger, whose name-the only name left-is Melville.

7. A: Tom assists with Hamish's chief puppeteer, who is not Jill (B). Paul (C) is chief puppeteer for the puppet Rex,* not Hamish. Sue (D) is chief puppeteer working with assistant Pam, not Tom. *Rex (E) is not a chief puppeteer at all, but rather a Kangaroo puppet.

8. C: Gale works to assist chief puppeteer, Paul, with the Kangaroo puppet named Rex. The Dragon (A) puppet named Hamish is operated by Ben and his assistant Tom. The Gorilla (B) puppet named Audrey is operated by Sue and her assistant Pam. The Tiger (D) puppet named Melville is operated by Jill and her assistant Dave. The passage does NOT include a lemur (E) puppet at all.

9. C: Stephen has lost all his games until now, so the score must be 3:0 in favor of his opponent. This narrows the choices down to (B) or (C). At least one game at table 1 has resulted in a tie, but Stephen has lost all of his games, so he must be at table 2 (C).

10. D: Assuming the players and scores are each listed consecutively by table, the leading player at table 1 is David, with the highest score of 3.

11. A: David (B) has white pieces, not black. Richie (C) has black pieces, but has NOT been in a tied game. Don (D) is currently leading his match and so is not tied. Terry (E) has white pieces, not black. By process of elimination, the only choice left is Mike, who has black pieces (A).

12. A: Currently, after three games with the fourth game in progress not scored yet, Don is leading his match and Richie (E) is not in the lead. Terry (B) is identified as playing at table 4, but no further information is given. No information is given about David (C) or Gerry (D) regarding who is winning at table 4.

13. E: To determine whether the device increased/decreased/did not change his car's mileage, Larry would need a baseline measurement of his car's average mileage before installing the device. Without this baseline to compare with post-installation mileage, Larry's conclusion is unsubstantiated. Car ages (A), city vs. highway driving (B), gasoline grades (C), and Steve's lying (D) would all affect mileages, but are immaterial when Larry cannot compare his car's current mileage to its mileage before device installation.

14. D: Xenon cannot be processed every other Monday. Oxygen is only processed on Tuesdays and Wednesdays, eliminating Mondays. The remaining three may be processed on any given Monday: Sulfur dioxide on any days except Fridays, methane on any days except Wednesdays, and liquid hydrogen on Mondays, Wednesdays, and Fridays.

15. D: Thursdays are most difficult, because Xenon cannot be processed every other Thursday, and oxygen (processed only on Tuesdays and Wednesdays) and liquid hydrogen (processed only on Mondays, Wednesdays, and Fridays) both cannot be processed on Thursdays. Mondays (A) are only restricted against processing xenon (alternate Mondays) and oxygen. Tuesdays (B) are only restricted against processing liquid hydrogen. Wednesdays (C) are only restricted against processing methane. Fridays (E) are only restricted against processing sulfur dioxide.

16. C: Liquid hydrogen is processed Monday, Wednesday, and Friday. Methane is processed any day except Wednesday. Xenon is not processed on alternate Mondays and Thursdays, but on all other days including Friday. Oxygen [(A), (D), (E)] is processed Tuesday and Wednesday, not Friday. Sulfur dioxide [(B), (E)] is not processed on Friday.

17. E: Liquid hydrogen is only processed on Monday, Wednesday, and Friday. Of these three days, on Wednesday liquid hydrogen and an additional three chemicals-xenon, oxygen, and sulfur dioxide-may be processed. On Monday, liquid hydrogen plus sulfur dioxide and methane can be processed. On Friday, liquid hydrogen plus xenon and methane can be processed.

18. E: With testing in progress, results are not yet definitive. The passage never indicates that preliminary results apply only to a small minority (A). Six cups of coffee daily is not necessarily higher than what many people drink, which the passage also does not identify (B). While generalizability of animal results to humans is doubted by many (C), the media relations person did NOT cite this objection, OR limited application of rat studies to human birth defects (D).

19. C: It helps to make a chart/table with cells for first name, surname, place in line, and food, first filling in the information given and then identifying the missing pieces through matching and elimination: Jessica Trotter was first in line and bought Cumberland sausage. Maggie Bore was second and bought pork pie. Annie Hazlitt was third and bought sliced ham. Lily Piggott was fourth and bought pork chops. Naomi Sowter was fifth and bought scotch eggs.

20. B: The pork pie was purchased by Maggie Bore, the second in line following the first customer, Jessica Trotter. Following them were (3) Annie Hazlitt, buying sliced ham; (4) Lily Piggott, buying pork chops; and (5) Naomi Sowter, buying scotch eggs. By arranging the given information in a table by first name, surname, place in line, and food, one can fill in the missing pieces through elimination and matching.

21. E: Naomi Sowter was fifth in line, buying scotch eggs after Lily Piggott, who was fourth, buying pork chops and followed Annie Hazlitt, who was third and bought sliced ham. Maggie Bore was second in line, preceding Annie Hazlitt and buying pork pie after Jessica, who was first in line and bought Cumberland sausage. Arranging known first names, surnames, places in line, and purchases into cells/boxes in a table/chart makes it easier to match/eliminate to induce/deduce missing pieces.
