1. What does the word Quarantine mean?

• A. Isolation
• B. Confinement away from the general population
• C. Treatment
• D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

2. What does the word 'composed' mean in the passage on the Water Cycle?

• A. To consist of.
• B. To create.
• C. To separate.
• D. To destroy.

Correct answer: A

Rationale: In the context of the Water Cycle, 'composed' means 'to consist of' parts. For instance, water is composed of hydrogen and oxygen atoms. Therefore, the correct meaning of 'composed' in this context is to consist of various components. Choice B, 'To create,' is incorrect as 'composed' refers to the makeup of something rather than the act of making or creating. Choices C and D, 'To separate' and 'To destroy,' are also incorrect as they do not align with the meaning of 'composed' in the passage.

3. A 3-volt flashlight uses a bulb with 60-ohm resistance. What current flows through the flashlight?

• A. o.05 amp
• B. o.5 amp
• C. 1.8 amp
• D. 18 amp

Correct answer: A

Rationale: : Using Ohm's Law, I = V / R: I = 3 / 60 = 0.05 amp. So, the correct current is 0.05 amp.

4. How do the intercostal muscles between the ribs assist with respiration?

• A. By protecting the delicate bronchioles and alveoli
• B. By signaling a decrease in intra-alveolar pressure
• C. By enlarging and reducing the space in the thorax
• D. By maintaining a medial separation between pleurae

Correct answer: C

Rationale: The intercostal muscles located between the ribs play a crucial role in respiration by aiding in the enlargement and reduction of the space in the thorax. During inspiration, these muscles contract, lifting the rib cage, which increases the volume of the thoracic cavity and allows the lungs to expand and fill with air. This process directly relates to the expansion of the thorax rather than protecting bronchioles and alveoli (Choice A), signaling intra-alveolar pressure changes (Choice B), or maintaining the separation between pleurae (Choice D). Therefore, the correct answer is C.

5. Select the meaning of the word 'intact' in the sentence: 'It is important that the bandage remain intact.'

• A. Dry
• B. Whole
• C. Uncovered
• D. Secure

Correct answer: B

Rationale: The correct answer is 'B: Whole'. In this context, 'intact' means undisturbed or whole, referring to the bandage being complete and not damaged. Choice A, 'Dry', is incorrect as it does not reflect the meaning of 'intact' in this sentence. Choice C, 'Uncovered', is also incorrect as 'intact' does not imply uncovered but rather complete. Choice D, 'Secure', is not the best fit as 'intact' in this context emphasizes the undamaged or whole nature of the bandage.
