1. Which term is most closely aligned with the definition of the term 'working man' as it is defined in the following passage? 'You will judge for yourselves if I promise too much for the working man, when I say that he will stand by such an enterprise with the utmost of his patience, his perseverance, sense, and support.'

• A. Plebeian
• B. Viscount
• C. Entrepreneur
• D. Bourgeois

Correct answer: A

Rationale: The correct answer is 'Plebeian.' In the given extract, the term 'working man' is associated with individuals who are part of the working class. Historically, plebeians were common working-class citizens. The passage emphasizes the dedication, patience, and support of the working man towards an enterprise, aligning with the characteristics attributed to plebeians in society. 'Viscount' is a noble title and not related to the working class. 'Entrepreneur' refers to a business person who takes risks to start a business, which is not the focus of the passage. 'Bourgeois' typically refers to the middle class, not specifically the working class like the term 'Plebeian.'

2. Identify the verb in the following sentence: The dog chased the fluffy squirrel around the oak tree.

• A. around
• B. chased
• C. squirrel
• D. the

Correct answer: B

Rationale: A verb is a word that expresses an action or state of being. In this sentence, 'chased' is the verb as it describes the action the dog is performing - chasing the fluffy squirrel. 'Around' is a preposition indicating location, 'squirrel' is a noun referring to the animal being chased, and 'the' is an article used to specify the squirrel. Therefore, the correct answer is 'chased.'

3. The resolution of an optical instrument, like a microscope, refers to its ability to distinguish between:

• A. Different colors of light
• B. The presence or absence of light
• C. Variations in intensity
• D. Very close, nearly identical objects

Correct answer: D

Rationale: The resolution of an optical instrument, such as a microscope, refers to its ability to distinguish between very close, nearly identical objects. This is crucial in microscopy to clearly visualize and differentiate fine details and structures. Resolving power plays a significant role in determining the quality and effectiveness of an optical instrument. Choices A, B, and C are incorrect because the resolution of an optical instrument does not primarily deal with different colors of light, presence or absence of light, or variations in intensity. Instead, it specifically focuses on the instrument's ability to differentiate between objects that are very close and nearly identical in nature.

4. Which of the following characteristics is part of a person's genotype?

• A. Brown eyes that appear hazel in the sunlight
• B. The CFTR gene, which causes cystic fibrosis
• C. Black hair that grows rapidly
• D. Being a fast runner

Correct answer: B

Rationale: The correct answer is B. A genotype refers to a person's genetic makeup, which includes specific genes like the CFTR gene responsible for cystic fibrosis. Genes are the units of heredity and are part of an individual's genotype, influencing various traits and characteristics. Choice A, brown eyes that appear hazel in the sunlight, refers to a phenotype, which is the observable characteristics resulting from the interaction of genes and the environment. Choice C, black hair that grows rapidly, also describes a phenotype rather than a genotype. Choice D, being a fast runner, is a trait influenced by a combination of genetic and environmental factors, but it does not directly relate to a specific gene in the genotype.

5. Chyle, a milky white fluid, is transported by lymphatic vessels from the:

• A. Lungs
• B. Intestines
• C. Kidneys
• D. Skin

Correct answer: B

Rationale: Chyle, a milky white fluid, is formed in the small intestine during digestion. It is composed of lymph and emulsified fats. Lymphatic vessels in the intestines, specifically lacteals, transport chyle from the intestines to the bloodstream for the distribution of nutrients throughout the body. The transport of chyle from the lungs, kidneys, or skin is not correct as these organs are not primarily involved in the production or transportation of chyle.
