1. What is the name for the smallest amount of an element that can exist independently and retain its chemical properties?

Correct answer: A

Rationale: The correct answer is 'Atom.' An atom is the fundamental unit of an element that can exist independently and retain its unique chemical properties. It consists of a nucleus containing protons and neutrons, surrounded by electrons. Choice B, 'Molecule,' is incorrect because a molecule is a combination of two or more atoms bonded together. Choice C, 'Compound,' is incorrect as a compound is a substance formed by the chemical combination of two or more different elements. Choice D, 'Mixture,' is incorrect since a mixture is a blend of two or more substances physically combined, but the individual components retain their properties.

2. A student gets 42 questions out of 48 correct on a quiz. What is the percentage of questions that the student answered correctly?

Correct answer: D

Rationale: To find the percentage of questions answered correctly, divide the number of correct questions by the total number of questions: 42/48 = 0.875. Multiply the result by 100 to express it as a percentage, which gives 87.5%. Therefore, the correct answer is 87.50%. Choice A (1.14%) is incorrect as it does not reflect the correct percentage. Choices B (82.50%) and C (85.00%) are also incorrect as they do not align with the calculation based on the given information.

3. The words 'aerobics' and 'aeronautics' both have the prefix 'aero' in common. What does 'aero' mean?

Correct answer: D

Rationale: The prefix 'aero' is derived from the Greek word 'aēr,' which means air. In words like 'aerobics' and 'aeronautics,' the prefix 'aero' refers to air-related activities or concepts. Therefore, 'air' is the correct meaning of the prefix 'aero.' Choices A, B, and C are incorrect. 'Light' does not relate to the prefix 'aero,' 'speed' and 'distance' are not associated with the concept of air as in 'aero,' making them incorrect answers.

4. To which of the following bone types do the spine and hips belong?

Correct answer: B

Rationale: The correct answer is B: Irregular bones. The spine and hips belong to the category of irregular bones. Irregular bones have complex shapes that do not fit into other bone type categories. These bones serve functions such as support and protection, and their shapes vary depending on their specific roles in the body. Choice A, curved bones, is incorrect because bones like ribs are typically described as curved, not the spine and hips. Choice C, flat bones, is incorrect as flat bones include the skull and ribs, but not the spine and hips. Choice D, long bones, is also incorrect because long bones include bones like the femur and humerus, which are elongated with a shaft and distinct ends, unlike the spine and hips.

5. Which of the following lobes of the brain is responsible for sensation, perception, and spatial reasoning?

Correct answer: C

Rationale: The parietal lobe is responsible for sensation, perception, and spatial reasoning. It plays a crucial role in processing sensory information, assisting in spatial orientation, and integrating various sensory inputs to create a comprehensive perception of the surrounding environment. The frontal lobe, although important for higher cognitive functions and motor skills, is not primarily responsible for sensation, perception, or spatial reasoning. The occipital lobe is mainly involved in visual processing, and the temporal lobe is primarily associated with auditory processing, memory, and emotions, making them incorrect choices for this question.
