1. If a rat can finish a maze in about 3 minutes, how much longer will it take the rat to finish the maze if a small backpack is put on it, reducing its speed by 50%?

Correct answer: C

Rationale: Reducing the rat's speed by 50% means it will take twice as long to finish the maze. Since the original time is 3 minutes, doubling that gives 6 minutes. Therefore, the total time will be 6 minutes, making the correct answer C. Choice A (3 minutes) is the original time it takes the rat to finish the maze, not the time with the backpack. Choice B (4 minutes) is not correct as reducing the speed by 50% would double the original time. Choice D (1.5 minutes) is incorrect as halving the time is not the effect of reducing the speed by 50%.

2. The ankle bone may be called the ___________.

Correct answer: A

Rationale: The ankle bone is commonly known as the talus, which is a prominent bone in the human foot that forms the lower part of the ankle joint. It plays a crucial role in supporting body weight and allowing the foot to move in various directions. The terms talon and fascine are not accurate when referring to the ankle bone. Talon usually refers to the claw of a bird or animal, while fascine is a bundle of sticks used in construction or military engineering. Fascia, on the other hand, is a band of connective tissue and not a bone.

3. Precipitous is best defined as being ____?

Correct answer: B

Rationale: The correct answer is B: 'Swift.' Precipitous is used to describe something that is steep, sheer, or done suddenly and without careful consideration. For example, a precipitous drop in the stock market. 'Slow' (Choice A), 'Gradual' (Choice C), and 'Delayed' (Choice D) do not align with the meaning of precipitous and are therefore incorrect.

4. What statement can be implied from the content of the article?

Correct answer: A

Rationale: The correct statement that can be implied from the content of the article is that diversity is interesting to learn about. The passage discusses different cultural methods of eating, highlighting the value of discovering these differences and learning new ways to do things. Choice B is incorrect as it focuses on a specific eating tool without capturing the broader message of cultural diversity. Choice C is incorrect as it suggests a superiority of European methods without considering the value of diversity. Choice D is incorrect as the passage mentions that space travel has created new challenges for consuming food, not necessarily making eating easier.

5. Multiply: 4/9 × 1 4/5 × 2/5.

Correct answer: A

Rationale: To multiply the fractions, convert the mixed numbers to improper fractions: 1 4/5 = 9/5. Then, multiply the fractions: (4/9) × (9/5) × (2/5) = 8/25. The correct answer is A. Choice B is incorrect as it does not match the result of the multiplication. Choice C is incorrect as it is not the result of multiplying the fractions. Choice D is incorrect as it is not the result of the given multiplication.
