1. What happens to the force of gravity between two objects when the distance between them is doubled?

• A. ) The force increases by a factor of 2
• B. The force increases by a factor of 4
• C. The force decreases by a factor of 2
• D. The force decreases by a factor of 4

Correct answer: d

Rationale: According to the inverse square law of gravity, the force of gravity decreases by a factor of 4 when the distance between two objects is doubled.

2. Which of the following is an example of a zoonotic disease?

• A. The common cold
• B. Influenza (the flu)
• C. Malaria
• D. HIV/AIDS

Correct answer: B

Rationale: Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

3. What is the process by which a cell divides into two or more new cells?

• A. Mitosis
• B. Meiosis
• C. Both mitosis and meiosis
• D. None of the above

Correct answer: A

Rationale: Rationale: Mitosis is the process by which a cell divides into two identical daughter cells. This type of cell division is essential for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Therefore, meiosis is not the process by which a cell divides into two or more new cells. Option C is incorrect because meiosis is not involved in the general process of cell division to produce new cells. Option D is incorrect because mitosis is the correct process for cell division.

4. What is the main topic of the passage?

• A. Benefits of bioremediation in cleaning oil spills.
• B. Dangers of microplastics to marine ecosystems.
• C. History of plastic production and its global impact.
• D. Comparison of different waste management strategies.

Correct answer: B

Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.

5. What is the author's stance towards the idea of smart cities?

• A. Strongly supportive, emphasizing only the benefits.
• B. Strongly critical, focusing solely on the drawbacks.
• C. Balanced and objective, highlighting both potential and concerns.
• D. Indecisive and unclear about the overall value of smart cities.

Correct answer: C

Rationale: The passage acknowledges both the promise and challenges of smart cities, demonstrating a balanced perspective.

6. Which type of white blood cell directly attacks and destroys pathogens like bacteria and viruses?

• A. Neutrophils
• B. Lymphocytes
• C. Monocytes
• D. Eosinophils

Correct answer: A

Rationale: The correct answer is A: Neutrophils. Neutrophils are a type of white blood cell that plays a crucial role in the innate immune response by directly attacking and destroying pathogens like bacteria and viruses. They are the most abundant type of white blood cell and are known for their rapid response to infections. Neutrophils work by engulfing and digesting pathogens through a process called phagocytosis. Lymphocytes (option B) are involved in adaptive immunity, producing antibodies and coordinating immune responses. Monocytes (option C) differentiate into macrophages and dendritic cells, playing a role in phagocytosis and antigen presentation. Eosinophils (option D) are primarily involved in combating parasitic infections and allergic reactions, not directly attacking bacteria and viruses.
