1. A car travels 210 miles using 7 gallons of gas. At the same rate of fuel efficiency, how many miles can it travel on 12 gallons?

   1. 300 miles
   2. 350 miles
   3. 360 miles
   4. 420 miles

   The car gets 210 / 7 = 30 miles per gallon. On 12 gallons it travels 30 x 12 = 360 miles.

2. A jacket originally priced at $80 is marked down 25%. At the register, an additional 10% is taken off the sale price. What is the final price?

   1. $48.00
   2. $52.00
   3. $54.00
   4. $56.00

   After 25% off: 80 x 0.75 = $60. Then 10% off $60: 60 x 0.90 = $54. The two discounts are applied one after the other, not added together.

3. One pump can fill a water tank in 6 hours, and a second pump can fill the same tank in 3 hours. Working together, how long will it take to fill the tank?

   1. 2 hours
   2. 3 hours
   3. 4.5 hours
   4. 9 hours

   The pumps fill 1/6 + 1/3 = 1/6 + 2/6 = 3/6 = 1/2 of the tank per hour. At half a tank per hour, the full tank takes 2 hours.

4. Solve for x: 3(x - 4) = 2x + 5

   1. x = 7
   2. x = 12
   3. x = 17
   4. x = 1

   Distribute to get 3x - 12 = 2x + 5. Subtract 2x from both sides: x - 12 = 5, then add 12: x = 17.

5. Simplify the expression (2x^3)^4.

   1. 8x^7
   2. 16x^12
   3. 16x^7
   4. 8x^12

   Raise each factor to the 4th power: 2^4 = 16 and (x^3)^4 = x^(3*4) = x^12, giving 16x^12.

6. A right triangle has legs measuring 9 and 12. What is the length of the hypotenuse?

   1. 15
   2. 21
   3. 18
   4. 13

   By the Pythagorean theorem, the hypotenuse equals the square root of (9^2 + 12^2) = square root of (81 + 144) = square root of 225 = 15.

7. Vigilant most nearly means

   1. exhausted
   2. watchful
   3. cheerful
   4. stubborn

   Vigilant means keeping careful watch for possible danger or difficulties, so 'watchful' is the closest synonym. The other choices describe unrelated states.

8. The mechanic gave a candid assessment of the car's problems. Candid most nearly means

   1. hesitant
   2. honest
   3. lengthy
   4. confusing

   Candid means truthful and straightforward, so 'honest' fits best. A candid assessment holds nothing back, unlike a hesitant or confusing one.

9. Honeybees do more than make honey. As they move from flower to flower gathering nectar, they carry pollen with them, allowing plants to produce fruit and seeds. Without this steady work, many of the crops that people depend on would fail to grow. What is the main idea of this passage?

   1. Honeybees are valuable because they help plants reproduce, not just because they make honey.
   2. Honeybees prefer flowers that produce the sweetest nectar.
   3. Most crops can grow perfectly well without any insects.
   4. Making honey is the most important thing bees do for people.

   The passage opens by saying bees do more than make honey and then explains how they help plants produce fruit and seeds. That broader role is the main idea.

10. The lighthouse keeper climbed the spiral stairs every evening at dusk to light the great lamp. On stormy nights he stayed awake until dawn, watching for ships that might drift too close to the rocks. His careful attention saved many crews from disaster. According to the passage, when did the keeper light the lamp?

    1. At noon each day
    2. Every evening at dusk
    3. Only during storms
    4. Whenever a ship appeared

    The passage states directly that the keeper climbed the stairs to light the lamp every evening at dusk. This is a stated detail.
