   A train travels at a constant speed of 60 miles per hour. How long will it take to travel 180 miles?

   • a.3.5 hours
   • b.2 hours
   • c.4 hours
   • d.3 hours

3. 3. Electronics Information

   A device that stores electrical charge is a:

   • a.inductor
   • b.resistor
   • c.transformer
   • d.capacitor

   Đáp án: d

   Giải thích: A capacitor stores electrical energy in an electric field between two plates. A resistor limits current, while an inductor stores energy in a magnetic field.

4. 4. Arithmetic Reasoning

   A mechanic charges $85 for the first hour of labor and $60 for each additional hour. What is the labor charge for a job that takes 5 hours?

   • a.$265
   • b.$325
   • c.$385
   • d.$425

   Đáp án: b

   Giải thích: The first hour costs $85 and the remaining four hours cost $60 each, so 4 x $60 = $240. Adding $85 + $240 gives $325.

5. 5. Arithmetic Reasoning

   A shipment of 1,250 items has a defect rate of 4 percent. How many items are not defective?

   • a.1,200 items
   • b.1,206 items
   • c.1,150 items
   • d.1,246 items

   Đáp án: a

   Giải thích: Four percent of 1,250 is 50 defective items, so 1,250 - 50 = 1,200 are good.

6. 6. Word Knowledge

7. 7. Paragraph Comprehension

   Coral reefs cover less than one percent of the ocean floor but shelter roughly a quarter of all marine species. The coral animal builds a stone skeleton, and generations of skeletons stack into a structure full of crevices. It is the crevices, more than the coral itself, that make the reef so crowded. The passage attributes the variety of reef life mainly to

   • a.the many hiding places
   • b.the warmth of the water
   • c.the clarity of the water
   • d.the coral animal's diet

   Đáp án: a

   Giải thích: The final sentence says it is the crevices, more than the coral itself, that make the reef so crowded.

8. 8. Mathematics Knowledge

   What is the distance between the points (1, 2) and (7, 10)?

   • a.14 units
   • b.100 units
   • c.10 units
   • d.8 units

   Đáp án: c

   Giải thích: The horizontal change is 6 and the vertical change is 8, so the distance is the square root of 36 + 64 = 100, which is 10.

9. 9. General Science

   A solar eclipse occurs when

   • a.the Earth passes between the moon and the sun
   • b.the moon moves into the Earth's own shadow
   • c.the moon passes between the Earth and the sun
   • d.the sun passes behind the far side of Earth

   Giải thích: In a solar eclipse the moon blocks the sun from part of the Earth's surface. When the moon moves into Earth's shadow instead, the result is a lunar eclipse.

10. 10. Mechanical Comprehension

    A 180-pound crate hangs from a 10-foot pole carried by two workers at its ends. If the crate hangs 3 feet from the first worker, how much of the load does that worker carry?

    • a.126 pounds
    • b.90 pounds
    • c.54 pounds
    • d.150 pounds

    Đáp án: a

    Giải thích: Taking moments about the far worker, the near worker's share is 180 x 7 / 10 = 126 pounds. The worker closer to the load always carries more of it.
