1. The author likely intended to use the phrase "interconnected sensors" to emphasize...

• A. The cost-effectiveness of smart city technology.
• B. The complexity and network-based nature of the system.
• C. The potential for environmental harm of sensor installation.
• D. The aesthetic appeal of modern urban infrastructure.

Correct answer: B

Rationale: "Interconnected" highlights the integration and communication between sensors, indicating a complex network approach.

2. What is the medical term for ingrown hair?

• A. Folliculitis
• B. Hirsutism
• C. Pseudofolliculitis Barbae
• D. Alopecia

Correct answer: C

Rationale: The correct answer is C: 'Pseudofolliculitis Barbae.' This term specifically refers to ingrown hairs commonly seen in the beard area. Folliculitis (A) is inflammation of the hair follicles, not necessarily due to ingrown hairs. Hirsutism (B) is excessive hair growth, unrelated to ingrown hairs. Alopecia (D) is hair loss, which is also not related to ingrown hairs. Therefore, 'Pseudofolliculitis Barbae' is the medical term specifically used to describe ingrown hairs in the beard area, making it the correct answer.

3. What is the main verb tense in the following sentence? "She had already left before I arrived."

• A. Present tense
• B. Past tense
• C. Future tense
• D. t perfect tense

Correct answer: D

Rationale: The verb "had left" is in the past perfect tense, indicating an action completed before another past action ("arrived").

4. What is the process of converting DNA into a protein called?

• A. Transcription
• B. Translation
• C. Replication
• D. Mutation

Correct answer: A

Rationale: Transcription is the process of converting DNA into a molecule called messenger RNA (mRNA). This mRNA molecule carries the genetic information from DNA to the ribosomes, where it is used to make proteins.

5. Which phenomenon describes the bending of light as it travels from one medium to another with differing densities?

• A. Reflection
• B. Refraction
• C. Diffraction
• D. Dispersion

Correct answer: B

Rationale: The correct answer is B: Refraction. Refraction is the phenomenon that describes the bending of light as it travels from one medium to another with differing densities. When light passes from one medium to another, such as from air to water, its speed changes, causing it to bend. This bending of light is what we observe when a pencil appears bent in a glass of water. Reflection, on the other hand, is the bouncing back of light when it hits a surface. Diffraction refers to the bending of light around obstacles, and dispersion is the separation of light into its different colors. Therefore, in this case, refraction is the most appropriate term to describe the bending of light as it moves between media with different densities.

6. How does polarization affect the intensity of light passing through a polarizing filter?

• A. All light passes through regardless of polarization.
• B. Light with the same polarization as the filter passes through, while others are blocked
• C. Light with higher intensity passes through, while weaker light is blocked.
• D. The intensity is reduced for all light, regardless of polarization.

Correct answer: B

Rationale: A polarizing filter only allows light waves with a specific polarization direction to pass through, reducing the intensity of waves with different orientations.
