1. Why do cicadas make a buzzing sound?

• A. To orient via echolocation
• B. To attract a mate
• C. To locate a food source
• D. To ward off predators

Correct answer: B

Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.

2. How many feet are in 9 yards?

• A. 45 ft
• B. 18 ft
• C. 36 ft
• D. 27 ft

Correct answer: D

Rationale: To convert yards to feet, you need to know that 1 yard is equal to 3 feet. Therefore, to find out how many feet are in 9 yards, you multiply 9 by 3, which equals 27 feet. Choice A (45 ft) is incorrect as it miscalculates by multiplying 9 by 5 instead of 3. Choice B (18 ft) incorrectly multiplies 9 by 2. Choice C (36 ft) is incorrect as it doubles the answer of 18 feet, which is also an incorrect calculation.

3. What is the definition of the term 'momentum' in physics?

• A. Force exerted on an object
• B. Speed of an object in motion
• C. Mass in motion
• D. Distance traveled per unit time

Correct answer: C

Rationale: Momentum in physics is the product of an object's mass and its velocity. It is a vector quantity that describes the motion of an object and is given by the formula p = mv, where p is momentum, m is mass, and v is velocity. Therefore, momentum is best described as the mass of an object in motion. Choice A, 'Force exerted on an object,' is incorrect because force is not equivalent to momentum. Choice B, 'Speed of an object in motion,' is incorrect because speed only considers the rate of motion and not the mass aspect. Choice D, 'Distance traveled per unit time,' is incorrect as it relates to speed and not momentum, which involves both mass and velocity.

4. What is the name for the flexible connection between bones at the wrist or ankle?

• A. Ligament
• B. Tendon
• C. Fascia
• D. Synovial joint

Correct answer: A

Rationale: The correct answer is A: Ligament. Ligaments are tough bands of tissue that connect bones to other bones at joints, providing stability and support. In the case of the wrist or ankle, ligaments play a crucial role in maintaining the structural integrity and allowing for proper movement of these joints. Tendons (option B) connect muscles to bones, not bones to bones. Fascia (option C) is a connective tissue that surrounds muscles and other structures, not connecting bones at joints. A synovial joint (option D) is a type of joint that allows for movement between bones, but it is not the flexible connection between bones at the wrist or ankle.

5. Which statement is not a detail from the passage?

• A. Promoters of dietary supplements can make any claims that are supported by research.
• B. GMP requirements for large manufacturers went into effect in 2008.
• C. The FDA regulates dietary supplements in the same way as prescription medications.
• D. Consumers should research supplement claims before making a purchase.

Correct answer: A

Rationale: The statement "Promoters of dietary supplements can make any claims that are supported by research" is not a detail from the passage. The passage mentions that manufacturers, not promoters, can make claims supported by research. The primary focus is on the regulations and manufacturing standards for dietary supplements. Choice B is a detail from the passage as it mentions the GMP requirements for large manufacturers going into effect in 2008. Choice C is incorrect as the passage states that FDA regulations for dietary supplements are not the same as those for prescription medications. Choice D is also supported by the passage, emphasizing that consumers should research supplement claims before making a purchase to ensure accuracy and safety.
