1. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. The constituents of an atomic nucleus consist of:

• A. Electrons and protons only
• B. Protons and neutrons only
• C. Electrons, protons, and neutrons
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: "Protons and neutrons only." This is because the atomic nucleus is composed of protons, which carry a positive charge, and neutrons, which are neutral. Electrons are found outside the nucleus in electron shells. Protons and neutrons are collectively known as nucleons and are responsible for the mass of the atom. Electrons are much lighter and are involved in chemical reactions and bonding. Therefore, the constituents of an atomic nucleus are specifically protons and neutrons, making option B the correct choice.

3. What is the primary difference between science and pseudoscience?

• A. Science uses complex terminology and jargon, while pseudoscience is easier to understand.
• B. Science relies on rigorous methodology and evidence, while pseudoscience thrives on personal anecdotes and testimonials.
• C. Science caters to specific fields of study, while pseudoscience encompasses broader life questions.
• D. Science is conducted by professionals, while pseudoscience is pursued by amateurs with limited knowledge.

Correct answer: B

Rationale: Both science and pseudoscience can explore similar topics, but their methods and reliance on evidence differentiate them.

4. The formula for body mass index (BMI) is BMI = weight (kg) / height (m)^2. If a patient's BMI is 25 and their height is 1.7m, what is their weight?

• A. 34kg
• B. 45kg
• C. 56kg
• D. 68kg

Correct answer: C

Rationale: 56kg: Rearrange the formula to solve for weight: weight = BMI * height^2.

5. Which sentence uses the word "literally" correctly?

• A. literally died laughing at that joke.
• B. He literally climbed a mountain of paperwork.
• C. Her eyes were literally sparkling with excitement.
• D. The house was literally haunted by ghosts.

Correct answer: B

Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.

6. The thymus gland, crucial for immune system development, is located in the:

• A. Chest
• B. Abdomen
• C. Pelvis
• D. Head and neck

Correct answer: A

Rationale: The thymus gland, an essential organ for immune system development, is located in the chest region, specifically in the upper part of the chest behind the breastbone. It plays a vital role in the maturation of T-cells, a type of white blood cell crucial for immune responses. The thymus gland is part of the lymphatic system and is most active during childhood and adolescence, gradually decreasing in size and function with age. Its location in the chest allows it to interact closely with other immune system components in the body, making it a key player in maintaining overall immune health.
