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 it mean if something is distended?

• A. Shrunken
• B. Swollen
• C. Narrow
• D. Flattened

Correct answer: B

Rationale: When something is described as distended, it means that it is swollen or expanded, not shrunken, narrow, or flattened. In a medical context, distention often refers to an abnormal swelling or enlargement of an organ or structure. 'Shrunken' is incorrect as it means reduced in size, 'narrow' is incorrect as it means not wide, and 'flattened' is incorrect as it means pressed or squeezed flat.

3. 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.

4. Which word describes a screen or filter?

• A. Permeable
• B. Incendiary
• C. Exuding
• D. Resilient

Correct answer: A

Rationale: The word 'permeable' refers to a material or surface that allows liquids, gases, or substances to pass through it, while screening or filtering out impurities. This makes it an appropriate descriptor for a screen or filter, which function by allowing certain elements to pass through while retaining others. Choices B, C, and D are incorrect: 'Incendiary' means causing fires, 'Exuding' means giving off or releasing, and 'Resilient' means able to withstand or recover from difficult conditions.

5. Choose the meaning of the word vent in the following sentence: 'A tube is used to vent the gases to the outside.'

• A. Block
• B. Trade
• C. Emit
• D. Inhale

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off. 'Trade' is incorrect as it refers to the exchange of goods or services. 'Inhale' is incorrect as it means to breathe in, which is the opposite of venting gases out.
