1. Which word best describes the relationship between population growth and smart cities in the passage?

• A. Cause and effect
• B. Analogy
• C. Contrast
• D. Similarity

Correct answer: A

Rationale: The passage identifies rapid population growth as a challenge that smart cities are proposed to address, establishing a causal connection.

2. What is the term for a group of organisms with the same genetic makeup?

• A. Population
• B. Clone
• C. Genotype
• D. Species

Correct answer: B

Rationale: Rationale: - A population (option A) refers to a group of individuals of the same species living in the same area. - Genotype (option C) refers to the genetic makeup of an individual organism. - Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. This term specifically refers to organisms with the same genetic makeup, making it the most appropriate choice for the question.

3. Which pronoun correctly replaces the underlined phrase in the sentence: "Jessica invited Sarah and me to the party, but I forgot to respond to her."

• A. We
• B. Us
• C. Ours
• D. Myself

Correct answer: C

Rationale: "Ours" clarifies that the response forgetting was a joint action by Jessica and the speaker.

4. Antigen-antibody binding is the principle behind:

• A. Vaccination
• B. Disinfection
• C. Sterilization
• D. antibiotic resistance

Correct answer: A

Rationale: Rationale: Antigen-antibody binding is the principle behind vaccination. When a vaccine containing antigens (weakened or killed pathogens) is introduced into the body, the immune system produces antibodies that bind to these antigens. This binding triggers an immune response, leading to the production of memory cells that provide immunity against future infections by the same pathogen. Vaccination helps the body develop immunity without causing the disease itself, thereby protecting individuals from infectious diseases. Disinfection and sterilization involve different processes to eliminate or reduce pathogens on surfaces or objects. Antibiotic resistance is a phenomenon where bacteria evolve to resist the effects of antibiotics and is not directly related to antigen-antibody binding.

5. Which neurotransmitter is associated with pleasure, reward, and motivation, and is often implicated in conditions such as addiction?

• A. Acetylcholine
• B. Dopamine
• C. Serotonin
• D. GABA (Gamma-aminobutyric acid)

Correct answer: b

Rationale: The correct answer is B: Dopamine. Dopamine is a neurotransmitter that is commonly associated with pleasure, reward, and motivation. It plays a crucial role in the brain's reward system and is often implicated in conditions such as addiction. Dopamine is released in response to rewarding stimuli, reinforcing behaviors that lead to pleasure. Acetylcholine is involved in muscle contraction and memory, not pleasure and reward. Serotonin is known for regulating mood and emotions, while GABA is an inhibitory neurotransmitter that helps reduce neural activity. Therefore, dopamine is the neurotransmitter most closely linked to pleasure, reward, and motivation in the brain.

6. What is the oxidation state of carbon in CH4?

• A. +1
• B. -1
• C. +2
• D. -4

Correct answer: d

Rationale: Each hydrogen atom has an oxidation state of +1, and the sum of oxidation states in CH4 is 0. Therefore, carbon has an oxidation state of -4.
