1. A stop sign has five equal sides, each measuring 25cm. What is its perimeter?

• A. 100cm
• B. 125cm
• C. 150cm
• D. 175cm

Correct answer: B

Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 5 * 25cm = 125cm.

2. Which of the following is an example of an aromatic hydrocarbon?

• A. Ethane
• B. Benzene
• C. Propane
• D. Butene

Correct answer: B

Rationale: Benzene is an example of an aromatic hydrocarbon. The other choices are aliphatic hydrocarbons.

3. What is the scientific name for the kneecap?

• A. Patella
• B. Femur
• C. Tibia
• D. Fibula

Correct answer: A

Rationale: The patella, commonly known as the kneecap, is a small, flat, triangular bone that sits at the front of the knee joint. It protects the joint from impact and helps to transmit force from the quadriceps muscle to the tibia (shinbone).

4. The term "bioaccumulate" refers to...

• A. The natural decomposition of organic materials.
• B. The buildup of a substance in living organisms.
• C. The contamination of seawater with chemical pollutants.
• D. The physical entanglement of animals with plastic debris.

Correct answer: B

Rationale: The passage describes microplastics entering food chains and accumulating in organisms, aligning with bioaccumulation.

5. What is the term for the time it takes for a wave to complete one full cycle?

• A. Frequency
• B. Amplitude
• C. Period
• D. Wavelength

Correct answer: c

Rationale: The period of a wave is the time taken for one complete oscillation or cycle.

6. Which term describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror?

• A. Aperture
• B. Focal length
• C. Refractive index
• D. Lens thickness

Correct answer: B

Rationale: The focal length is the term that describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror. It is a crucial parameter in optics and is used to determine the magnification and image formation in optical systems. The other options (A) Aperture, (C) Refractive index, and (D) Lens thickness are not directly related to the point where parallel rays converge or diverge.
