1. Many people wait until they feel thirsty before drinking water, but thirst is a late signal. By the time it appears, the body may already be mildly dehydrated, and physical and mental performance begin to slip. Soldiers training in hot weather are therefore taught to drink on a schedule rather than by feel, taking small amounts at regular intervals. Drinking too much at once can also cause problems, so the goal is steady intake across the day, not large volumes consumed all at once.

   1.

   According to the passage, why are soldiers taught to drink on a schedule?

   • A.

     Thirst is a late warning of dehydration.

   • B.

     Large volumes of water are easier to carry.

   • C.

     Schedules reduce the amount of water needed.

   • D.

     Hot weather makes water taste unpleasant.

   Answer: A.

   The passage says thirst is a late signal and that the body may already be dehydrated when it appears, which is why a schedule replaces drinking by feel. The passage says nothing about carrying water or taste.

2. Researchers have long known that sleep helps the brain store what it learned during the day, but the role of each sleep stage is still being worked out. Deep, slow-wave sleep appears to strengthen facts and events, while the lighter REM stage seems to help with skills and emotional memories. In one study, students who slept after memorizing word pairs recalled more of them than students who stayed awake for the same number of hours. The authors concluded that an all-night study session may do more harm than good.

   2.

   Based on the passage, which conclusion is best supported?

   • A.

     REM sleep is more important than slow-wave sleep.

   • B.

     Staying awake all night improves recall of word pairs.

   • C.

     Scientists fully understand how each sleep stage works.

   • D.

     Students who sleep after studying remember more.

   Answer: D.

   The study described found that students who slept recalled more word pairs than those who stayed awake. The passage says the role of each stage is still being worked out, so neither the ranking of stages nor full understanding is supported.

3. Every spring the city repaints the crosswalks downtown, and every spring the paint is faded again by autumn. The paint is cheap, which is why it is chosen, but it must be reapplied so often that the labor costs far exceed what a more durable thermoplastic marking would cost over five years. The council insists it is saving money. It is saving money only in the sense that the bill for the paint itself is small; the total cost tells a different story.

   3.

   The author's attitude toward the city council's choice is best described as

   • A.

     supportive

   • B.

     neutral

   • C.

     critical

   • D.

     amused

   Answer: C.

   The author argues that the council's claim of saving money is misleading because labor costs exceed the price of a better material. Pointing out that the total cost tells a different story is criticism, not support or neutral reporting.

4. Pilots run through a printed checklist before every takeoff, even if they have flown the same aircraft thousands of times. The practice began in the 1930s after a highly experienced crew crashed a new bomber because they forgot to release a control lock. Investigators concluded that the aircraft was not too difficult to fly but too complex to fly from memory. Checklists have since spread to operating rooms, construction sites, and power plants, wherever a missed step can be costly.

   4.

   Which statement best expresses the main idea of the passage?

   • A.

     Experienced pilots do not need checklists.

   • B.

     Complex tasks are hard to do from memory.

   • C.

     The 1930s bomber was poorly designed.

   • D.

     Surgeons adopted checklists before pilots did.

   Answer: B.

   The passage's point is that even skilled people miss steps in complex tasks, which is why checklists were created and spread to other fields. The crash involved an experienced crew, so experience alone is not enough, and the investigators said the aircraft was not too hard to fly.

5. To jump-start a car safely, first park the working vehicle close to the disabled one without letting the cars touch, and turn off both engines. Connect the red clamp to the positive terminal of the dead battery, then the other red clamp to the positive terminal of the good battery. Connect the black clamp to the negative terminal of the good battery, and attach the final black clamp to an unpainted metal surface on the disabled car, away from the battery. Start the working car, wait a few minutes, then try the disabled car.

   5.

   According to the passage, where should the final black clamp be attached?

   • A.

     To the negative terminal of the dead battery

   • B.

     To the positive terminal of the good battery

   • C.

     To unpainted metal on the disabled car

   • D.

     To the engine of the working car

   Answer: C.

   The passage says the last black clamp goes on an unpainted metal surface on the disabled car, away from the battery. Attaching it to the dead battery's negative terminal is the common mistake the passage is steering readers away from.

6. Our office switched to a four-day week last year as an experiment. Managers worried that output would fall, and a few customers grumbled about Friday coverage. Twelve months later, the number of completed projects is slightly higher than the year before, sick days have dropped by a third, and two employees who had planned to leave decided to stay. Friday coverage is now handled by a rotating pair of staff. The experiment has been extended for a second year.

   6.

   Which of the following can be inferred from the passage?

   • A.

     The company plans to return to a five-day week soon.

   • B.

     The four-day week caused a significant decline in output.

   • C.

     The experiment went well enough to be continued.

   • D.

     Most customers stopped doing business with the office.

   Answer: C.

   Higher project completion, fewer sick days, retained employees, and an extension for a second year all point to a positive result. Output rose slightly rather than falling, and only a few customers grumbled.

7. The negotiations had stalled for weeks, with each side repeating the same demands at every session. On the final day before the deadline, the mediator proposed a compromise that neither delegation loved but both could accept. She later said the key was finding terms that let each side leave the room claiming a partial victory. Within an hour the agreement was signed.

   7.

   As used in the passage, the word stalled most nearly means

   • A.

     come to a halt

   • B.

     sped up

   • C.

     ended successfully

   • D.

     become secret

   Answer: A.

   Stalled means came to a standstill. The next phrase, with each side repeating the same demands, shows that nothing was moving forward until the mediator's compromise. The talks ended successfully only after the stall was broken.

8. The Pony Express carried mail between Missouri and California for only eighteen months, from April 1860 to October 1861. Riders changed horses every ten to fifteen miles at relay stations and handed the mail to a fresh rider roughly every seventy-five to one hundred miles. A letter could cross the country in about ten days, a remarkable speed for the time. The service ended two days after the transcontinental telegraph was completed, which could send a message across the same distance in minutes.

   8.

   According to the passage, why did the Pony Express end?

   • A.

     The riders refused to work in winter.

   • B.

     The horses were needed for the Civil War.

   • C.

     The transcontinental telegraph made it obsolete.

   • D.

     The relay stations were too expensive to maintain.

   Answer: C.

   The passage links the end of the service directly to the completion of the telegraph, which carried messages in minutes instead of ten days. Winter, the war and station costs are not mentioned.

9. The young lieutenant was known for her candor. When the colonel asked whether the plan would work, she said plainly that it would not, and explained why. Some officers thought her blunt; others found her refreshing. Either way, no one ever had to guess what she really thought. Over time, even those who had bristled at her directness came to rely on it, because her assessments were never shaded to please anyone.

   9.

   As used in the passage, the word candor most nearly means

   • A.

     caution

   • B.

     humor

   • C.

     ambition

   • D.

     honesty

   Answer: D.

   Candor means frank, open honesty. The lieutenant says plainly what she thinks and never shades her assessments, which describes honesty rather than caution or ambition.

10. Many new runners try to improve by running hard every day, and most of them end up injured or exhausted within a few months. Coaches recommend the opposite: most runs should be easy enough to hold a conversation, with only one or two faster sessions a week. The easy miles build the heart, lungs, and tendons that make hard efforts possible. Progress feels slow at first, but runners who follow this approach are far more likely to still be running a year later.

    10.

    The author's main purpose is to

    • A.

      persuade new runners to run easy most of the time

    • B.

      describe the history of long-distance running

    • C.

      warn readers that running is too dangerous to attempt

    • D.

      explain how to choose running shoes

    Answer: A.

    The passage contrasts the common mistake of running hard every day with the coaches' advice to keep most runs easy, and ends by stating the benefit of that approach. It does not discuss history or shoes, and it encourages running rather than warning against it.
