1. What is the main point of the passage?

• A. Climate change is a myth and does not pose any significant threat to the planet.
• B. The negative consequences of climate change are inevitable and irreversible.
• C. Human actions are the primary cause of climate change, and global efforts are needed to address it.
• D. Technological advancements alone can provide quick and easy solutions to the climate crisis.

Correct answer: C

Rationale: The passage clearly identifies human activities as the cause of climate change and emphasizes the need for global action, aligning with C.

2. Katherine tells one of the staff, “I don’t have time to discuss the matter with you now. See me

• A. Smoothing
• B. Compromise
• C. Avoidance
• D. Restriction

Correct answer: B

Rationale: The correct answer is B: 'Compromise.' In this scenario, Katherine is willing to engage with the staff member but suggests they postpone the discussion to a later time. This demonstrates a willingness to find a middle ground or reach a mutual agreement, which aligns with the concept of compromise. 'Smoothing' involves downplaying differences to maintain harmony, 'Avoidance' is ignoring or postponing the issue altogether, and 'Restriction' refers to limiting the interaction or communication. Therefore, 'Compromise' best fits the situation where Katherine is open to discussing the matter at a more suitable time.

3. The speed of light in a vacuum is measured in units of:

• A. Meters per second
• B. Hertz
• C. Candela
• D. Newton

Correct answer: A

Rationale: The correct answer is A: 'Meters per second.' The speed of light in a vacuum is a fundamental constant of nature and is approximately 299,792,458 meters per second. This speed is constant and does not vary based on the frequency or wavelength of light. Hertz (B) is a unit of frequency, Candela (C) is a unit of luminous intensity, and Newton (D) is a unit of force. Understanding the units used to measure the speed of light is important in physics and related fields to accurately describe the propagation of light in different mediums.

4. Which of the following is the main function of the kidneys?

• A. To filter waste products from the blood
• B. To produce urine
• C. To regulate blood pressure
• D. To produce hormones that help to control blood sugar levels

Correct answer: A

Rationale: Rationale: A) To filter waste products from the blood: The main function of the kidneys is to filter waste products, excess ions, and water from the bloodstream to form urine, which is then excreted from the body. This process helps maintain the body's internal environment by regulating the balance of electrolytes, fluid volume, and pH levels. B) To produce urine: While the kidneys do produce urine as a result of filtering the blood, the primary function is to filter waste products rather than solely producing urine. C) To regulate blood pressure: The kidneys do play a role in regulating blood pressure by controlling the volume of blood and the concentration of electrolytes in the body, but their main function is waste filtration. D) To produce hormones that help to control blood sugar levels: While the kidneys do produce hormones like erythropoietin and renin that play a role in various physiological processes, such as red

5. In the reaction 2H2 + O2 → 2H2O, how many moles of oxygen are required to react completely with 4 moles of hydrogen?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: 2

Rationale: The balanced equation indicates a 1:1 ratio between H2 and O2, so 4 moles of H2 require 4 moles of O2, and 2 moles of H2 require 2 moles of O2.

6. Which organelle is responsible for packaging and secreting proteins into the extracellular space?

• A. Golgi apparatus
• B. Mitochondria
• C. Ribosomes
• D. Endoplasmic reticulum

Correct answer: A

Rationale: Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins into vesicles for secretion outside the cell or for use within the cell. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in packaging and secreting proteins. C) Ribosomes: Ribosomes are responsible for protein synthesis, where they translate mRNA into proteins. They are not involved in packaging and secreting proteins into the extracellular space. D) Endoplasmic reticulum: The endoplasmic reticulum (ER) plays a role in protein synthesis and folding, but it is the rough ER specifically that is involved in synthesizing proteins that are then transported to the Golgi apparatus for further processing and packaging. The Golgi apparatus is primarily responsible for packaging and secreting proteins
