Question #1
The witness gave a candid account of the accident. Candid most nearly means
Correct answer: B
Explanation
Candid means open and honest, so frank is the closest synonym. Rehearsed is the tempting wrong idea, since a prepared story is the reverse of a spontaneous, truthful one. Brief and tearful describe length and emotion, not honesty.

Question #2
The storm began to abate by midnight. Abate most nearly means
Correct answer: A
Explanation
Abate means to become less intense, so diminish is the closest synonym. Strengthen is the opposite. Linger is tempting because a storm may stay around, but it says nothing about decreasing in force.

Question #3
Current flows easily in only one direction through a
Correct answer: A
Explanation
A diode conducts when forward biased and blocks current when reverse biased, which is why it is used in rectifiers. A resistor opposes current equally in both directions. Capacitors and transformers work with changing voltage and do not pass current in just one direction.

Question #4
Gears used to transmit power between two shafts whose axes intersect at 90° are usually
Correct answer: A
Explanation
Bevel gears have conical faces and connect shafts that meet at an angle, most often 90°. Spur gears connect parallel shafts. Idler gears sit between two gears to reverse direction, and internal gears also work on parallel shafts.

Question #5
What is the value of √225?
Correct answer: B
Explanation
15 × 15 = 225, so √225 = 15. The value 25 is tempting because it comes from dropping a digit, but 25 × 25 = 625. Checking by squaring the candidate rules out 14 and 16.

Question #6
An engine overheats when the car idles in traffic, but the temperature returns to normal at highway speed. The coolant level is full and there are no leaks. The most likely cause is a
Correct answer: C
Explanation
At highway speed, ram air moves enough air through the radiator, but at idle the fan must do that job. An inoperative fan fits the symptoms exactly. A stuck-open thermostat would cause an engine that runs too cool, not hot.

Question #7
An ohmmeter is used to measure
Correct answer: D
Explanation
An ohmmeter measures resistance in ohms, normally with the circuit de-energized. It supplies its own small test current. Current is measured with an ammeter, and frequency with a frequency counter.

Question #8
A 6-foot pole of negligible weight is carried horizontally by two workers, one at each end. A 120-lb crate hangs from the pole 2 feet from worker A. How many pounds does worker A support?
Correct answer: B
Explanation
Take moments about worker B's end: worker A × 6 ft = 120 lb × 4 ft, so A = 80 lb. Worker B carries the other 40 lb. The crate is closer to A, so A carries the larger share.

Question #9
A delivery truck is bought for $20,000. It loses 15 percent of its value during the first year and then 10 percent of its remaining value during the second year. What is the truck's value after two years?
Correct answer: C
Explanation
After year one the truck is worth 85 percent of $20,000, or $17,000. Year two takes 10 percent of that remaining value, so it is worth 90 percent of $17,000, or $15,300. Adding the percents (25 percent of $20,000) gives $15,000, a common error because the second loss applies to the reduced value.

Question #10
Honeybees tell other bees where food is by dancing. The angle of the dance compared with vertical shows the direction of the food relative to the sun, and the length of the dance shows how far away the food is. According to the passage, the length of the dance shows
Correct answer: A
Explanation
The passage states that the length of the dance shows how far away the food is. The angle, not the length, shows direction, which is the tempting wrong choice. The passage says nothing about the amount of food or the number of bees.
