1. A children's toy consists of a half cylinder (diameter 10cm, height 8cm) attached to a cube with side lengths of 5cm. What is the total volume of the toy?

• A. 125 cu cm
• B. 200 cu cm
• C. 275 cu cm
• D. 350 cu cm

Correct answer: C

Rationale: Calculate the volume of the half cylinder and the cube separately, then add them up.

2. Which division of the autonomic nervous system is responsible for the "rest and digest" response, promoting relaxation and conservation of energy?

• A. Sympathetic nervous system
• B. Parasympathetic nervous system
• C. Somatic nervous system
• D. Central nervous system

Correct answer: b

Rationale: The correct answer is B, the parasympathetic nervous system. This division of the autonomic nervous system is responsible for the "rest and digest" response, promoting relaxation and conservation of energy. When activated, it slows the heart rate, increases digestion, and helps the body rest and recover. The sympathetic nervous system, on the other hand, is responsible for the "fight or flight" response, preparing the body for action. The somatic nervous system controls voluntary movements, and the central nervous system consists of the brain and spinal cord, coordinating all nervous system functions.

3. Which sentence uses strong verbs to create a more vivid image?

• A. The car moved slowly down the street.
• B. The car drove sluggishly down the road.
• C. The car inched down the avenue.
• D. The car traveled down the thoroughfare.

Correct answer: C

Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."

4. What is the scientific study of the relationships between organisms and their environment?

• A. Zoology
• B. Botany
• C. Ecology
• D. Genetics

Correct answer: C

Rationale: Rationale: A) Zoology is the scientific study of animals. B) Botany is the scientific study of plants. C) Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. D) Genetics is the scientific study of genes, heredity, and variation in living organisms, which is not directly related to the relationships between organisms and their environment.

5. In a neutral atom, the number of electrons:

• A. Must be equal to the number of protons.
• B. Must be less than the number of protons.
• C. Must be greater than the number of neutrons.
• D. Can vary depending on the atom's temperature.

Correct answer: A

Rationale: Must be equal to the number of protons - For electrical neutrality, the positive charge of protons must be balanced by the negative charge of an equal number of electrons.

6. When a car brakes to a stop, friction between the tires and the road acts as:

• A. A balanced force
• B. An unbalanced force causing acceleration
• C. An unbalanced force causing the car to remain at rest
• D. No force at all

Correct answer: B

Rationale: Friction opposes the car's motion, acting as an unbalanced force that decelerates the car and brings it to a stop.
