1. What does the word Querulous mean?

• A. Shouting
• B. Complaining
• C. Crying
• D. Praising

Correct answer: B

Rationale: The correct answer is B: 'Complaining.' Querulous is an adjective that describes someone who is constantly complaining or irritable. It is not related to shouting (Choice A) or crying (Choice C). Choice D, 'Praising,' is the opposite of the meaning of querulous and therefore incorrect.

2. What word meaning 'once a year' fits best in the sentence: 'The _____ family reunion picnic was held at the Jones farm instead of the county park.'

• A. regular
• B. annual
• C. biennial
• D. holiday

Correct answer: B

Rationale: The word 'annual' refers to something that happens once every year. 'Regular' could mean frequent but doesn't specify a yearly event. 'Biennial' refers to something occurring every two years, while 'holiday' relates to a special day of celebration, not necessarily an annual event.

3. The frequency of an alternating current (AC) refers to the number of times it changes direction per unit time. This is measured in:

• A. Hertz
• B. Amperes
• C. Volts
• D. Ohms

Correct answer: A

Rationale: The frequency of an alternating current (AC) is measured in Hertz (Hz), which denotes the number of times the current changes direction per unit time. Hertz is the unit for frequency, while amperes measure current, volts measure voltage, and ohms measure resistance. Therefore, the correct answer is Hertz (Hz). Choices B, C, and D are incorrect because amperes measure current intensity, volts measure voltage potential, and ohms measure resistance, not the frequency of an alternating current.

4. What does concave mean?

• A. Rounded inward
• B. Rounded outward
• C. Straight
• D. Flat

Correct answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

5. Which of the following statements about the respiratory system is true?

• A. The respiratory system consists of all the organs involved in breathing
• B. Organs included in the respiratory system are the nose, pharynx, larynx, trachea, bronchi, and lungs
• C. The respiratory system conveys oxygen into our bodies and removes carbon dioxide from our bodies
• D. All of the Above

Correct answer: D

Rationale: The correct answer is D. The respiratory system consists of all the organs involved in breathing, including the nose, pharynx, larynx, trachea, bronchi, and lungs. Additionally, the respiratory system is responsible for conveying oxygen into our bodies and removing carbon dioxide from our bodies. Therefore, all the statements provided are true, making option D the correct choice. Options A, B, and C are all accurate statements about the respiratory system, reinforcing the correctness of choosing option D.
