1. Select the meaning of the underlined word in the following sentence. The night nursing staff is accountable for those records.

Correct answer: C

Rationale: In this context, the word 'accountable' means responsible. The night nursing staff is responsible for those records, meaning they are the ones who are answerable and expected to ensure proper care and maintenance of the records. Choice A, 'Receptive,' does not fit the context as it means willing to listen or accept information. Choice B, 'Notorious,' means famous or well-known, usually for something negative, which is not the intended meaning here. Choice D, 'Preoccupied with,' means to be engrossed or absorbed in something, which does not convey the meaning of being responsible as intended in the sentence.

2. What is stated in this paragraph?

Correct answer: D

Rationale: The correct answer is D. The paragraph explains that harsh voice qualities usually result from too much tension in the throat and jaw. It further discusses how tension tightens muscles, leading to unpleasant voice tones. While the paragraph addresses the issue of harsh voices, it does not mention that only some men have harsh voices (choice A) or that relaxed people often exhibit this quality (choice B). Additionally, the paragraph does not touch upon whether everyone finds harsh voices irritating (choice C), only stating that not everyone may be bothered by it.

3. What is the primary function of the respiratory system?

Correct answer: B

Rationale: The primary function of the respiratory system is to facilitate the exchange of gases. It transports oxygen from the air into the bloodstream, which is crucial for cellular respiration and providing energy to the cells. Additionally, it removes carbon dioxide, which is a waste product that needs to be eliminated. Choices A, C, and D are incorrect because while the respiratory system does remove carbon dioxide, its primary role is oxygen transport, not nutrient delivery, sound, or speech production.

4. A farmer wants to plant trees at the outside boundaries of his rectangular field with dimensions 650 meters × 780 meters. Each tree requires 5 meters of free space all around it from the stem. How much free area will be left?

Correct answer: A

Rationale: To calculate the area taken by the trees, we need to account for the space each tree requires. Each tree needs 5 meters of free space all around it, totaling 10 meters added to each dimension. Therefore, the new dimensions of the field are (650-10) meters by (780-10) meters. Calculating the area of the new field: (640m × 770m = 492,800m²). To find the free area remaining, subtract the new field's area from the original field's area: 507,000m² - 492,800m² = 14,200m². Therefore, the free area left after planting the trees is 14,200m². Choice A is the correct answer as it represents the free area left after planting the trees.

5. Which phrase should be moved to improve sentence clarity? 'He opened the door slowly, trying not to wake the baby.'

Correct answer: A

Rationale: Placing 'trying not to wake the baby' at the beginning as in option A clarifies the purpose of the action right away, improving the sentence's flow.
