1. Which type of joint is found in the knee?

• A. Ball and socket joint
• B. Hinge joint
• C. Pivot joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is a hinge joint. The knee is a hinge joint that allows for flexion and extension movements, enabling the leg to bend and straighten. This type of joint is designed for movement along one plane, similar to a door hinge. Choice A, ball and socket joint, is incorrect as this type of joint allows for a wider range of motion in multiple directions, unlike the knee joint. Choice C, pivot joint, and Choice D, saddle joint, are also incorrect as they do not accurately describe the type of joint found in the knee.

2. Her guileless manner is one of her most noticeable qualities. What does guileless mean?

• A. Deceptive
• B. Straightforward
• C. Complex
• D. Untrustworthy

Correct answer: B

Rationale: The correct answer is B: 'Straightforward.' Guileless means innocent, sincere, and without deceit. It describes someone who is honest and straightforward in their actions and speech. Choices A, C, and D are incorrect. 'Deceptive' means misleading or dishonest, 'Complex' means having many intricate parts, and 'Untrustworthy' means not reliable or trustworthy, all of which are opposite in meaning to guileless.

3. A 110-volt hair dryer delivers 1,525 watts of power. How many amperes does it draw?

• A. 167.75 amperes
• B. 1.635 amperes
• C. 1.415 amperes
• D. 13.9 amperes

Correct answer: D

Rationale: To determine the amperes drawn by the hair dryer, we use the formula: Amperes = Watts / Volts. The hair dryer operates at 1,525 watts with 110 volts. Dividing 1,525 watts by 110 volts yields 13.9 amperes. Therefore, the correct answer is 13.9 amperes. Choices A, B, and C are incorrect because they do not result from the correct calculation using the formula.

4. A synonym is a word _____ a meaning similar to another word.

• A. that has
• B. that gives
• C. which has
• D. which gives

Correct answer: A

Rationale: The correct phrase to use in this context is 'that has,' indicating possession or similarity between words. Synonyms are words that have meanings similar to those of other words, making choice A the most appropriate selection. Choices B, C, and D are incorrect as they do not correctly convey the relationship of possessing similar meanings between words.

5. What is the main function of the digestive system?

• A. To break down food and absorb nutrients
• B. To regulate body temperature
• C. To transport nutrients
• D. To produce hormones

Correct answer: A

Rationale: The main function of the digestive system is to break down food into nutrients through the process of digestion. Once the food is broken down, the nutrients are absorbed into the bloodstream and utilized by the body for various functions. Choice B, regulating body temperature, is incorrect as it is the function of the body's thermoregulatory system, not the digestive system. Choice C, transporting nutrients, is incorrect as the digestive system primarily focuses on breaking down and absorbing nutrients rather than transporting them. Choice D, producing hormones, is also incorrect as hormone production is mainly carried out by endocrine glands and not the digestive system.
