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. Select the meaning of the underlined word in the following sentence. All volatile liquids should be stored and labeled correctly.

• A. Unstable
• B. Abnormal
• C. Lethal
• D. Blended

Correct answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.

3. What does contrite mean?

• A. Guilty
• B. Regretful
• C. Shameful
• D. Pleased

Correct answer: B

Rationale: The correct answer is B: 'Regretful.' Contrite means feeling regret or remorse. Choice A, 'Guilty,' does not fully capture the meaning of contrite as it implies a judgement of culpability rather than a feeling of remorse. Choice C, 'Shameful,' is incorrect as it focuses on the emotion of shame rather than regret. Choice D, 'Pleased,' is the opposite of what contrite means, as it signifies satisfaction or happiness, which is contradictory to feeling regretful or remorseful.

4. Which sentence uses the word 'present' as an adjective?

• A. She gave a present to her friend
• B. She was present at the meeting
• C. She made a present for her friend
• D. The teacher presented the award

Correct answer: B

Rationale: The sentence 'She was present at the meeting' uses 'present' as an adjective. In this context, 'present' describes her state of being at the meeting. The other choices use 'present' as a verb (to give), a noun (a gift), and a verb (to show), making them incorrect in the context of looking for the adjective use of 'present'.

5. What does 'insidious' mean?

• A. Immediate and obvious
• B. So gradual as to not become apparent for a long time
• C. Sudden and severe
• D. Quick and detectable

Correct answer: B

Rationale: The correct definition of 'insidious' is 'So gradual as to not become apparent for a long time.' This term describes something that develops slowly and may not be noticed initially. Choice A, 'Immediate and obvious,' is incorrect because 'insidious' implies the opposite of being immediate. Choice C, 'Sudden and severe,' is incorrect because 'insidious' suggests a slow and subtle progression, not sudden. Choice D, 'Quick and detectable,' is incorrect because 'insidious' does not indicate something quick or easily detectable.
