1. What can be inferred about the data collected by smart cities?

• A. It is easily accessible and transparent to the public.
• B. It is solely used for optimizing infrastructure and services.
• C. It may raise privacy concerns for individual citizens.
• D. It is always accurate and free from technical errors.

Correct answer: C

Rationale: The passage specifically mentions concerns about data privacy, implying potential issues for individuals.

2. Which property of a substance refers to its ability to be stretched into thin wires without breaking?

• A. Conductivity
• B. Viscosity
• C. Ductility
• D. Malleability

Correct answer: c

Rationale: Ductility is the property that describes a substance's ability to be stretched into thin wires without breaking.

3. Where does most of the chemical digestion and absorption of nutrients occur?

• A. Mouth
• B. Stomach
• C. Small intestine
• D. Large intestine

Correct answer: C

Rationale: Rationale: The small intestine is where most of the chemical digestion and absorption of nutrients occur in the digestive system. This is because the small intestine is lined with villi and microvilli, which increase the surface area available for absorption. Enzymes secreted by the pancreas and bile from the liver aid in breaking down food into smaller molecules that can be absorbed through the intestinal wall into the bloodstream. The stomach primarily functions in the mechanical breakdown of food and the initial stages of protein digestion, while the large intestine is mainly responsible for absorbing water and electrolytes from the remaining indigestible food particles. The mouth is involved in the initial mechanical breakdown of food through chewing and some chemical digestion of carbohydrates by salivary enzymes, but the majority of nutrient absorption occurs in the small intestine.

4. A new invention claims to solve the energy crisis. What criteria should you use to evaluate this claim?

• A. The inventor's qualifications and credentials.
• B. The technology's cost-effectiveness and affordability.
• C. Evidence of independent testing and scientific validation.
• D. Testimonials from celebrities and public figures.

Correct answer: C

Rationale: When evaluating a claim about solving the energy crisis, it is crucial to look for evidence of independent testing and scientific validation. This ensures that the technology has been rigorously assessed and verified by experts in the field, providing credibility to the invention's effectiveness. Testimonials from celebrities and public figures (option D) may not provide reliable information about the technology's actual capabilities. The inventor's qualifications and credentials (option A) are important but do not guarantee the technology's success. Cost-effectiveness and affordability (option B) are significant factors but should be considered alongside scientific validation to assess the overall impact and feasibility of the invention.

5. The beautiful flowers brightened the room. Which word is the adverb form of the adjective "beautiful"?

• A. beautiful
• B. beautifully
• C. beautification
• D. beautify

Correct answer: B

Rationale: Adverbs are formed from adjectives by adding "-ly" (usually).

6. The process by which a cell divides to produce two daughter cells is called:

• A. Mitosis
• B. Meiosis
• C. Differentiation
• D. Transformation

Correct answer: A

Rationale: The correct answer is A: "Mitosis." Mitosis is the process of cell division in which a cell duplicates its chromosomes and divides into two identical daughter cells. This is a crucial mechanism for growth, repair, and maintenance of multicellular organisms. Meiosis (option B) is a different type of cell division that produces gametes with half the number of chromosomes. Differentiation (option C) refers to the process by which cells become specialized for specific functions. Transformation (option D) is a term used in molecular biology to describe the uptake of foreign DNA by a cell. In this question, the specific process of cell division leading to the production of two daughter cells aligns with mitosis.
