1. The electrolytes in human bodies include sodium, potassium, calcium, and ___________, among others.

• A. magnesium
• B. manganese
• C. magnetite
• D. manganite

Correct answer: A

Rationale: Magnesium is another essential electrolyte in the human body, along with sodium, potassium, and calcium. Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, regulating blood pressure, and supporting the immune system. Manganese (Choice B), magnetite (Choice C), and manganite (Choice D) are not electrolytes found in the human body. Manganese is a mineral but not an electrolyte, while magnetite and manganite are compounds and not essential electrolytes for bodily functions.

2. What does Constrict mean?

• A. To expand
• B. To draw together
• C. To freeze
• D. To dissolve

Correct answer: B

Rationale: The correct answer is B: 'To draw together.' Constrict means to narrow or squeeze, making something smaller or tighter. This is the opposite of expanding (choice A), freezing (choice C), and dissolving (choice D), which do not involve the action of drawing together or becoming smaller.

3. What is another word for elated?

• A. Edified
• B. Confused
• C. Flabbergasted
• D. Delighted

Correct answer: D

Rationale: The word 'elated' means to be ecstatically happy or joyful. Similarly, 'delighted' also means to be extremely pleased or filled with joy. Therefore, 'delighted' is another word that could be used to express the same meaning as 'elated.' Choices A, B, and C are incorrect. 'Edified' means to instruct or enlighten, 'confused' means to be unclear or bewildered, and 'flabbergasted' means to be astonished or amazed, which do not convey the same meaning as 'elated.'

4. The accident _____ if the motorist had obeyed the speed limit sign.

• A. could have happened
• B. never would have happened
• C. wouldn't have occurred
• D. could happen

Correct answer: B

Rationale: The correct answer is 'never would have happened.' This choice correctly expresses the hypothetical outcome that did not occur due to the motorist obeying the speed limit sign. The phrase 'never would have happened' is the most suitable option in this context as it indicates a past event that was prevented by following a certain condition. Choice A ('could have happened') is incorrect as it does not convey the same level of certainty and definiteness as 'never would have happened.' Choice C ('wouldn't have occurred') is close but lacks the emphasis on the event not taking place at all. Choice D ('could happen') is in the present tense and does not fit the context of a past hypothetical situation.

5. Choose the meaning of the word 'waft' in the following sentence: The steady breeze caused dry leaves to waft over the creek.

• A. Sink
• B. Dive
• C. Wave
• D. Float

Correct answer: D

Rationale: In this sentence, the word 'waft' is used to describe the movement of dry leaves over the creek in response to the steady breeze. 'Waft' means to float gently through the air. The correct meaning of 'waft' in this context is to float. Choices A, B, and C are incorrect because 'sink' means to go down below the surface of something, 'dive' means to plunge headfirst into water or another substance, and 'wave' means to move one's hand to and fro in greeting or as a signal.
