• Question 701:

  During a single week, from Monday through Friday, tours will be conducted of a company's three divisions -- Operations, Production, Sales. Exactly five tours will be conducted that week, one each day. The schedule of tours for the week

  must conform to the following restrictions:

  Each division is toured at least once.

  The Operations division is not toured on Monday.

  The Production division is not toured on Wednesday.

  The Sales division is toured on two consecutive days, and on no other days.

  If the Operations division is toured on Thursday, then the Production division is toured on Friday.

  If in the week's tour schedule the division that is toured on Monday is not the division that is toured on Tuesday, then which one of the following could be true of the week's schedule?

  A. A tour of the Sales division is scheduled for someday earlier in the week than is any tour of the Production division.
  B. A tour of the Operations division is scheduled for some day earlier in the week than is any tour of the Production division.
  C. The Sales division is toured on Monday.
  D. The Production division is toured on Tuesday.
  E. The Operations division is toured on Wednesday.
  E. The Operations division is toured on Wednesday.

  After several questions about days that include the same entity, we have one about days with different entities. That's a little tougher but still manageable. Monday and Tuesday are different. Well, Monday is never an O day, so Monday will be either P or S. Yet our two S's are consecutive, so the latter option is out.

• Question 702:

  In a lab, the scientists have been performing tests on pregnant lab rats with caffeine. These rats were given the equivalent amount of caffeine that a person would consume with 6 cups of coffee every day. The caffeine increase also increased

  the occurrence of birth defects.

  A media relations person told reporters that the government would not require warning labels on products that contain caffeine, as the testing was continuing, and it may have different results in the future, and the government did not want to

  lose credibility.

  Of the following statements, which is the most in line with the statement that was made by the media relations person?

  A. If a warning applies only to a small minority of people is inappropriate
  B. Six cups of coffee per day is much higher than what a person typically drinks
  C. The conclusive nature of studies that have been performed on animals are doubted
  D. Studies on rats don't provide us with much data regarding birth defects in humans
  E. The significance of birth defects due to the use of caffeine is unclear
  E. The significance of birth defects due to the use of caffeine is unclear

• Question 703:

  Books updating the classification systems used by many libraries are not free -- in fact they are very expensive. The only way to sell copies of them is to make the potential buyers believe they need to adopt the most recent system. Thus, these frequent changes in the classification systems are just a ploy by the publishers to make libraries buy their products.

  The reasoning above is most vulnerable to criticism because it

  A. claims without providing warrant that the books are unreasonably expensive
  B. concludes that a possible ulterior motive must be the only motive
  C. fails to consider that there may be potential buyers of these books other than libraries
  D. concludes that there is no need ever to change classification systems
  E. fails to consider that the libraries cannot afford to buy every book they want
  B. concludes that a possible ulterior motive must be the only motive

  ---

  In this flaw question, the author errs in arguing that the only possible reason to change the library classification systems is for publishers to make money. Perhaps there are other, less suspicious reasons for doing so.

• Question 704:

  Five racing drivers, Alan, Bob, Chris, Don, and Eugene, enter into a contest that consists of 6 races. The results of all six races are listed below: Bob always finishes ahead of Chris. Alan finishes either first or last. Eugene finishes either first

  or last. There are no ties in any race.

  Every driver finishes each race. In each race, two points are awarded for a fifth place finish, four points for fourth, six points for third, eight points for second, and ten points for first.

  If Don finishes third in the third race, which of the following must be true of that race?

  A. Alan finishes first.
  B. Eugene finishes first.
  C. Bob finishes second.
  D. Chris finishes second.
  E. Alan finishes fifth.
  C. Bob finishes second.

  ---

  If Don finishes third, the order for this race will be: Alan/Eugene, Bob, Don, Chris, Alan/Eugene. Bob will finish second.

• Question 705:

  On a Tuesday, an accountant has exactly seven bills -- numbered 1 through 7 -- to pay by Thursday of the same week. The accountant will pay each bill only once according to the following rules:

  Either three or four of the seven bills must be paid on Wednesday, the rest on Thursday.

  Bill 1 cannot be paid on the same day as bill 5.

  Bill 2 must be paid on Thursday.

  Bill 4 must be paid on the same day as bill 7.

  If bill 6 is paid on Wednesday, bill 7 must be paid on Thursday.

  If bill 4 is paid on Thursday, which one of the following is a pair of bills that could also be paid on Thursday?

  A. 1 and 5
  B. l and 7
  C. 3 and 5
  D. 3 and 6
  E. 6 and 7
  B. l and 7

  ---

  If bill 4 is paid on Thursday, then so is bill 7 (Rule 4). Again, that's four bills on Thursday (2, 7, 4, and 1/5), so the rest (6, 3, and 1/5) must be on Wednesday. Now we need a pair of bills that could be paid on Thursday.

• Question 706:

  In a school function ceremony, seven students, Amy, Bob, Chad, Dom, Elisa, Fischer, and Grant have to deliver their performances in seven consecutive slots, not necessarily in the order of their given names. The following information is known about the order in which the students perform: Chad performs immediately before Dom Grant performs sometime after Chad There are exactly two performances made between the performances of Amy and Elisa

  What is the latest slot in which Chad could perform?

  A. Second
  B. Third
  C. Fourth
  D. Fifth
  E. Sixth
  D. Fifth

  ---

  We need to find the latest performance slot of Chad. This is a relatively easier question.

  We know very well that D must follow C. Also, G must come after D.

  Thus, the latest position of C occurs when G is 7th, D is 6th, and hence, C is 5th.

  General

  Let us denote the seven slots using the numbers 1 through 7 as shown below:

  

  We need to fill in the names of the performers in each slot depending on the information provided.

  Let us name the performers Amy, Bob, Chad, Dom, Elisa, Fischer, and Grant as A, B, C, D, E, F and G.

  Let us look at the information given in the question stem and see what we have got:

  1.

  Since Chad performs immediately before Dom, we can write "CD" as an element implying that there is no one else performing between them.

  2.

  Since Grant performs sometime after Chad, and Chad and Dom are consecutive performers, Grant must perform after Dom as well. Thus, we can represent the information as shown below:

  The "..." above implies that there could be none or at least 1 performer between D and G.

  3.

  There are exactly two performers between Amy and Elisa. This information can be represented as shown below:

  

  

  Thus, we see that the above information is NOT sufficient to assign even one of the performers to his/her corresponding slot number. This implies that there would possibly be multiple solutions to the arrangements of the performers. Thus, in order to solve the questions, we would need to use the information given in the questions.

• Question 707:

  The six messages on an answering machine were each left by one of Fleure, Greta, Hildy, Liam, Pasquale, or Theodore, consistent with the following:

  At most one person left more than one message.

  No person left more than three messages.

  If the first message is Hildy's, the last is Pasquale's.

  If Greta left any message, Fleure and Pasquale did also.

  If Fleure left any message, Pasquale and Theodore did also, all of Pasquale's preceding any of Theodore's.

  If Pasquale left any message, Hildy and Liam did also, all of Hildy's preceding any of Liam's

  If the only message Pasquale left is the fifth message, then which one of the following could be true?

  A. Hildy left the first message.
  B. Theodore left exactly two messages.
  C. Liam left exactly two messages.
  D. Liam left the second message.
  E. Fleure left the third and fourth messages.
  C. Liam left exactly two messages.

  ---

  A P in 5 means we'll need to hear from H and L, with all the H's before all the L's. Since P's only message is fifth, we can't have an H in 1, since that would force a P in 6. That kills option [Hildy left the first message.]., and after a little more thought, it kills options [Liam left the second message.] and [Fleure left the third and fourth messages.] as well. If an L is second, then an H is first, and we have the same problem. So [Liam left the second message.] is out. Similarly, if F is third and fourth, then we need a T after we hear from P (Rule 5). So we're looking at this scenario: __ __ F F P T.

  But we still need to hear from H and L, in that order, and the only available positions are the first and second positions. We still can't have H in 1, and so [Fleure left the third and fourth messages.] is impossible. Once you have it down to options [Theodore left exactly two messages.] and [Liam left exactly two messages], you only have to check one, although you could guess if you were running short of time. Let's look at option [Theodore left exactly two messages.] first. If we hear from T twice, then we can't put all the T's after all the P's, and so we can't hear from either F or G (contrapositives of Rules 4 and 5). But now we don't have enough messages! T leaves exactly 2, and P,H, and L leave exactly 1. That's only 5 messages, soB.is impossible. So option [Liam left exactly two messages.] is correct. If L left two messages, the sequence F H L L P T works fine.

• Question 708:

  A new bank has decided to stay open only on weekends - all day Saturday and Sunday - and no other days. The bank has hired two managers (U and V), Four tellers (W,X,Y, and Z), and two operation officers (S and T), for a total of exactly

  eight full-time employees.

  No part-time employees are hired.

  Each employee works a complete day when working.

  A manager must be on duty each day.

  The managers cannot work on the same day.

  At least two tellers must be working on the same day.

  W and X will not work on the same day.

  S and Z will only work on Saturday.

  No employee can work on consecutive days, but each employee must work on Saturday or Sunday.

  Which one of the following is a complete and accurate list of the employees who have the possibility of working on Sunday?

  A. UWYZ
  B. UWYS
  C. UVWXT
  D. UVWXYT
  E. UVWXYTS
  D. UVWXYT

  ---

  U,V,W,X,Y,Z and T have the possibility of working on Sunday; S and Z do not.

• Question 709:

  Few animals brave the midday heat of the Sahara Desert. An exception is the silver ant, which chooses this time of day to leave its nest and scout for food, typically the corpses of heat-stricken animals. Even the silver ant, however, must be careful: at such times they can become victims of the heat themselves.

  Which one of the following, if true, LEAST helps to explain the silver ant's choice of scavenging times?

  A. The chief predators of the silver ant must take cover from the sun during midday.
  B. The cues that silver ants use to navigate become less reliable as the afternoon progresses.
  C. Other scavengers remove any remaining corpses as soon as the temperature begins to drop in the afternoon.
  D. The temperature inside the silver ants' nests often exceeds the surface temperature during the hottest times of the day.
  E. Silver ants cool themselves by climbing onto small pieces of dried vegetation to take advantage of random light breezes.
  E. Silver ants cool themselves by climbing onto small pieces of dried vegetation to take advantage of random light breezes.

  ---

  Four of the five choices explain why the silver ant scouts for food in the blazing midday heat of the Sahara Desert, notwithstanding the little critters' vulnerability to heat. The absence of predators [The chief predators of the silver...] would

  certainly explain why that time of day would seem fortuitous. So would the greater ease of picking up navigational cues, [The cues that silver ants use to...]; better get the scouting done now rather than later. That better-now-than-later idea is

  picked up by option [Other scavengers remove any...] as well: The later the ant waits, [Other scavengers remove any...] suggests, the less food there is to forage. And [The temperature inside...] suggests that it's all just a matter of relativity.

  If it's hotter inside their nests than outside of them, who can blame the ants for getting out?

  In contrast to those four eminently reasonable explanations, correct choice [Silver ants cool themselves by] sidesteps the whole issue. "Random light breezes" could come along at any time of day, and so the insects' own particular form of air

  conditioning is of no help in explaining why the ants choose to forage during the blazing midday.

• Question 710:

  Ethicist: Both ASA and TPA are clot-dissolving agents. Recent studies show that the more expensive agent, TPA, would save at most two more lives than would ASA out of every 50 cardiac patients to whom they are post operatively administered. However, since the relatives of the patients who die simply because they were given the less expensive medicine would be particularly grieved, the financial saving involved in using ASA over TPA must also be weighed against such considerations.

  Which one of the following most accurately expresses the conclusion of the ethicist's argument?

  A. ASA should never be given to postoperative cardiac patients in place of TPA.
  B. TPA is a slightly more effective clot-dissolving agent than ASA.
  C. The extra expense of TPA cannot be weighed simply against the few additional lives saved.
  D. SA is a less expensive clot-dissolving agent than TPA.
  E. Relatives of a patient who has died grieve more if the patient received ASA rather than TPA.
  C. The extra expense of TPA cannot be weighed simply against the few additional lives saved.

  ---

  Next we're asked to figure out the conclusion of the ethicist's argument, so let's paraphrase: Of two clot-dissolving agents, the costlier one, TPA, would save at most two more lives out of every 50 cardiac patients than would ASA when given after an operation. But, since relatives of those who don't survive surgery would feel worse if the less effective, cheaper ASA were given, one shouldn't base the decision of which drug to use on financial concerns alone. Choices [TPA is a slightly more effective...], [SA is a less expensive...] and [Relatives of a patient who has died grieve...] repeat the facts of the matter; they are the evidence for the conclusion summarized in choice [The extra expense of TPA cannot be...]. We know the last part of the last sentence is the conclusion because it is prescriptive; it says what the author thinks should be done, based on all of the evidence given before. It's the only choice that passes the Training One Sentence Test; that is, if all the author were allowed was one sentence, choice [The extra expense of TPA cannot be...] is the statement that would best convey his point. Choices [TPA is a slightly more effective...], [SA is a less expensive...] and [Relatives of a patient who has died grieve...] are all too narrow to encapsulate the entire argument; as we saw, each is a piece leading up to the main point.
