1. Based on the following evidence, what is the most likely reason that spoiled food left out in the open often contains fly larvae?

• A. The spoiled food evolves into fly larvae.
• B. Since the food is left out in the open, flies lay eggs in the food.
• C. Fly larvae are spontaneously generated by the spoiled food.
• D. People only imagine they see fly larvae in the spoiled food.

Correct answer: B

Rationale: The correct answer is B. Flies laying eggs in the food when it is left exposed to the air is a common occurrence and a logical explanation for the presence of fly larvae in spoiled food. Choice A is incorrect as food cannot evolve into fly larvae; fly larvae come from eggs laid by flies. Choice C is incorrect as fly larvae do not spontaneously generate from spoiled food but rather develop from eggs laid by flies. Choice D is incorrect as the presence of fly larvae in spoiled food is a real phenomenon, not merely imagined by people.

2. Which of the following lobes in the cerebral cortex is primarily responsible for processing and integrating sensory information received from the rest of the body?

• A. frontal lobe
• B. occipital lobe
• C. parietal lobe
• D. temporal lobe

Correct answer: C

Rationale: The parietal lobe is the correct answer because it is primarily responsible for processing and integrating sensory information received from the rest of the body, including touch, pressure, temperature, and pain. This lobe plays a crucial role in spatial awareness, perception, and attention to sensory stimuli. It helps individuals make sense of the world around them and is essential for various sensory processes. The frontal lobe (choice A) is more associated with functions like reasoning, planning, and problem-solving. The occipital lobe (choice B) is responsible for processing visual information. The temporal lobe (choice D) is involved in functions like memory, auditory processing, and language comprehension, but it is not the primary lobe responsible for processing and integrating sensory information from the body.

3. How is work defined in terms of force and displacement?

• A. Work is the product of force and displacement in any direction
• B. Work is done only when the displacement is vertical
• C. Work is done only when the force and displacement are perpendicular
• D. Work is the product of force and displacement in the direction of the force

Correct answer: D

Rationale: Work is defined as the product of the force applied on an object and the displacement of the object in the direction of the force. This means that work is only done when the force and displacement are in the same direction. If the force and displacement are not in the same direction, only the component of the force in the direction of the displacement contributes to the work done. Therefore, choice D correctly defines work in terms of force and displacement. Choices A, B, and C are incorrect because work is specifically calculated based on the force and displacement in the direction of the force, not in any direction, only when the displacement is vertical, or when the force and displacement are perpendicular.

4. Which vitamin plays a crucial role in calcium absorption in the small intestine?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D plays a crucial role in calcium absorption in the small intestine by enhancing the absorption of calcium and phosphorus. This helps in regulating the levels of these minerals in the body, which are essential for maintaining healthy bones. Vitamin A (Choice A) is important for vision and immune function, but it is not directly related to calcium absorption. Vitamin C (Choice B) is primarily known for its role in collagen synthesis and antioxidant functions, not calcium absorption. Vitamin E (Choice D) acts as an antioxidant and is not directly involved in calcium absorption in the small intestine.

5. Which of the following is a MAJOR consequence of a stroke?

• A. Irregular heart rhythm.
• B. Rapid weight gain or loss.
• C. Brain damage due to interrupted blood flow.
• D. Chronic fatigue and muscle weakness.

Correct answer: C

Rationale: A major consequence of a stroke is brain damage due to interrupted blood flow. Strokes occur when blood flow to the brain is blocked or reduced, leading to the death of brain cells. This interruption in blood flow results in brain damage, which can cause physical and cognitive impairments such as paralysis, speech difficulties, memory problems, and sensory disturbances. The severity and location of the stroke determine the extent of the consequences experienced by the individual. Choices A, B, and D are incorrect. Irregular heart rhythm is not a direct consequence of a stroke but may occur as a complication. Rapid weight gain or loss and chronic fatigue with muscle weakness are not typically considered major consequences of a stroke, which primarily affects the brain due to interrupted blood flow.
