1. Which of the following is another name for the voice box?

• A. Alveoli
• B. Larynx
• C. Trachea
• D. Pharynx

Correct answer: B

Rationale: The correct answer is B, 'Larynx.' The larynx is commonly referred to as the voice box because it plays a crucial role in sound production. It contains vocal cords and functions in speech and singing. Choice A, 'Alveoli,' are small air sacs in the lungs involved in gas exchange. Choice C, 'Trachea,' is the windpipe that connects the larynx to the bronchi. Choice D, 'Pharynx,' is the throat area located behind the mouth and nasal cavity, responsible for the passage of food and air.

2. After a hurricane struck a Pacific island, donations began flooding into a disaster relief organization. The organization provided four options for donors. What percentage of the funds was donated to support construction costs?

• A. 49%
• B. 23%
• C. 18%
• D. 10%

Correct answer: B

Rationale: The correct answer is B (23%). The information was obtained from the pie chart which indicated that 23% of the funds were allocated to support construction costs. Choice A (49%), Choice C (18%), and Choice D (10%) are incorrect as they do not reflect the accurate percentage designated for construction costs according to the data provided.

3. Bile, a digestive juice, is produced by which organ?

• A. Stomach
• B. Liver
• C. Pancreas
• D. Small intestine

Correct answer: B

Rationale: Bile is a digestive juice produced by the liver. It is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The stomach (Choice A) produces gastric juices, not bile. The pancreas (Choice C) produces digestive enzymes and bicarbonate but not bile. The small intestine (Choice D) is where bile is released to aid in digestion but is not the organ that produces bile.

4. What happens to the force of gravity between two objects when the distance between them is doubled?

• A. The force increases by a factor of 2
• B. The force increases by a factor of 4
• C. The force decreases by a factor of 2
• D. The force decreases by a factor of 4

Correct answer: D

Rationale: According to the law of universal gravitation, the force of gravity between two objects is inversely proportional to the square of the distance between them. When the distance is doubled, the force decreases by a factor of 2 squared, which is 4. Therefore, the force decreases by a factor of 4. Choice A is incorrect because the force doesn't increase when the distance is doubled. Choice B is incorrect as the force doesn't increase but actually decreases. Choice C is incorrect as the force decreases by a factor of 4, not 2.

5. Which of the following are functions of the liver?

• A. Supports waste disposal
• B. Aids in blood clotting through plasma protein synthesis
• C. Emulsifies fats through bile production
• D. All of the above

Correct answer: D

Rationale: The liver performs various essential functions in the body. It supports waste disposal by breaking down toxins and producing bile to eliminate waste, aids in blood clotting through the synthesis of plasma proteins like fibrinogen, and emulsifies fats by producing bile that helps in fat digestion. All the statements accurately describe functions of the liver, making option D 'All of the above' the correct choice. Option A is incorrect as it oversimplifies the waste disposal function without mentioning the breakdown of toxins. Option B is incorrect as it only focuses on blood clotting and not the other functions of the liver. Option C is incorrect as it solely emphasizes fat emulsification and does not cover the liver's other crucial roles.
