1. Faraday's law of electromagnetic induction states that a changing magnetic field in a conductor induces a/an:

• A. Increase in resistance
• B. Electromotive force
• C. Static electric charge
• D. Decrease in capacitance

Correct answer: B

Rationale: Faraday's law of electromagnetic induction states that a changing magnetic field induces an electromotive force in a conductor. This electromotive force is responsible for generating electricity in power plants and various electrical devices. The induced current is a result of the changing magnetic field, not an increase in resistance (choice A), static electric charge (choice C), or a decrease in capacitance (choice D). Hence, the correct answer is B.

2. Which word in the following sentence functions as the direct object: 'The nurse helped the patient with the medication'?

• A. helped
• B. nurse
• C. patient
• D. medication

Correct answer: C

Rationale: In the sentence 'The nurse helped the patient with the medication,' the direct object is 'patient' because it receives the action of being helped. The direct object typically answers the question 'whom' or 'what' after the verb. In this case, 'the patient' is the one being helped by the nurse, making it the direct object. Choices A, B, and D are incorrect. 'Helped' is the verb, 'nurse' is the subject performing the action, and 'medication' is part of a prepositional phrase and does not directly receive the action of the verb.

3. Subtract 2 5\8 - 7\8 and reduce.

• A. 1 & 5\8
• B. 1 & 1\4
• C. 1 & 6\8
• D. 1 & 3\4

Correct answer: A

Rationale: Subtract the fractions first: 2 5\8 - 7\8 = 1 & 5\8.

4. What is the meaning of the word viable as used in the last paragraph?

• A. Reasonable
• B. Unresolved
• C. Contemporary
• D. Consistent

Correct answer: A

Rationale: In the context of the passage, "viable" means reasonable or feasible, referring to the acceptability of acupuncture as a treatment option based on the study's results. This definition aligns with the implications made in the conclusion of the study, thus supporting option A.

5. Which muscle is responsible for breathing?

• A. Diaphragm
• B. Intercostal muscles
• C. Rectus abdominis
• D. Pectoralis major

Correct answer: A

Rationale: The diaphragm is the primary muscle responsible for breathing. It is a large, dome-shaped muscle located at the base of the chest cavity. When it contracts, it flattens, increasing the volume of the chest cavity and causing inhalation. When it relaxes, it returns to its dome shape, decreasing the volume of the chest cavity and causing exhalation. The intercostal muscles, located between the ribs, assist the diaphragm in breathing by expanding and contracting the chest cavity. The rectus abdominis and pectoralis major are not directly involved in the process of breathing.
