1. The epidermis is classified as which of the following?

• A. Cell
• B. Tissue
• C. Organ
• D. System

Correct answer: B

Rationale: The epidermis is classified as a tissue, more specifically as a layer of cells that form the outermost part of the skin. It is composed of multiple layers of cells that protect underlying tissues and regulate various functions related to the skin. Choice A, Cell, is incorrect because the epidermis is not just a single cell but rather a collection of cells. Choice C, Organ, is incorrect because the epidermis is not an organ on its own but rather a part of an organ, the skin. Choice D, System, is incorrect because the epidermis is not a system but rather a component of the integumentary system.

2. Why did Strauss set up a net during the construction of the Golden Gate Bridge?

• A. For suspension
• B. For balance
• C. For aesthetics
• D. For safety

Correct answer: D

Rationale: Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.

3. Which word is not spelled correctly in the context of the following sentence? Everyone in the fraternity found the four boys' pranks sophomoric.

• A. Everyone
• B. fraternity
• C. boys'
• D. sophomoric

Correct answer: C

Rationale: The word 'boys'' should be spelled as 'boys' in this context. The correct possessive form of the plural noun 'boys' does not require an apostrophe before the final S, which indicates possession. In this sentence, the intent is to show that the pranks belong to the four boys collectively, so the correct possessive form is 'boys' without the additional apostrophe.

4. What is the meaning of the word 'elasticity' in the last paragraph?

• A. Something that is able to resist and be flexible
• B. Something that is like plastic
• C. Something that is dynamic and electrifying
• D. Something that is silly

Correct answer: A

Rationale: 'Elasticity' refers to the ability of the arterial walls to resist and be flexible, which affects blood pressure. In the provided extract, it is mentioned that an increase in blood pressure can occur if the arterial walls lose some of their elasticity with age or disease. This demonstrates that elasticity refers to the property of being able to resist and be flexible, supporting choice A as the correct answer. The other choices, B, C, and D, do not accurately reflect the concept of elasticity in the context of arterial walls and blood pressure.

5. For the core of an electromagnet, a material with high:

• A. Resistivity is ideal
• B. Permeability is preferred
• C. Permittivity is crucial
• D. Dielectric strength is essential

Correct answer: B

Rationale: A material with high permeability is preferred for the core of an electromagnet because it allows magnetic field lines to pass through it easily, enhancing the strength of the magnetic field generated. Choice A is incorrect because high resistivity would impede the flow of current in the coil, reducing the strength of the magnetic field. Choice C is incorrect as permittivity is related to electric fields, not magnetic fields. Choice D is also incorrect because dielectric strength is about insulating materials against breakdown under an electric field, not relevant to enhancing magnetic fields.
