1. What is the difference between polygenic inheritance and pleiotropy?

• A. Polygenic inheritance involves multiple genes influencing one trait, while pleiotropy involves one gene affecting multiple traits.
• B. Polygenic inheritance is found in simple Mendelian traits, while pleiotropy is found in complex traits.
• C. Polygenic inheritance is always quantitative, while pleiotropy can be qualitative or quantitative.
• D. Both involve multiple genes and multiple traits, but the specific mechanisms differ

Correct answer: A

Rationale: - Polygenic inheritance refers to the situation where a trait is influenced by multiple genes, each contributing a small effect to the phenotype. These traits often show continuous variation and are not easily categorized into discrete categories. - Pleiotropy, on the other hand, occurs when a single gene influences multiple, seemingly unrelated traits. This means that a mutation in one gene can lead to multiple phenotypic effects across different traits or characteristics. - Therefore, the key difference between polygenic inheritance and pleiotropy lies in the number of genes involved in influencing a trait (multiple genes in polygenic inheritance vs. one gene in pleiotropy) and the direction of influence (one trait affected by multiple genes in polygenic inheritance vs. multiple traits affected by one gene in pleiotropy).

2. How does the concept of leading double lives contribute to the overall message of the play?

• A. It shows the characters' true personalities and the superficial nature of their social roles.
• B. It reveals the hypocrisy and superficiality of the characters.
• C. It deepens the complexity of the characters and the societal norms they navigate.
• D. It complicates the narrative by adding layers of deception and irony.

Correct answer: B

Rationale: The correct answer is B. In Wilde's play, 'The Importance of Being Earnest,' the characters' practice of leading double lives serves to reveal their hypocrisy and superficiality. This aligns with the central theme of the play, which satirizes the absurdities and trivialities of the British aristocracy. By showcasing the characters' dual nature through their double lives, the play effectively critiques the shallow social roles they inhabit. Choice A is incorrect because the concept of leading double lives does not necessarily show the characters' true personalities but rather their deceptive and hypocritical behaviors. Choice C is incorrect as while leading double lives may deepen the complexity of the characters, the primary focus is on exposing their hypocrisy and shallowness. Choice D is also incorrect as the concept of double lives does add layers of deception, but the key message lies in revealing the characters' superficiality and hypocrisy.

3. What is the approximate metric equivalent of 7 inches?

• A. 3.2 cm
• B. 2.8 cm
• C. 15.4 cm
• D. 17.8 cm

Correct answer: D

Rationale: The correct answer is D: 17.8 cm. To convert inches to centimeters, you can use the conversion factor 1 inch = 2.54 cm. Therefore, 7 inches is equal to 7 * 2.54 = 17.78 cm, which rounds to 17.8 cm. Choices A, B, and C are incorrect because they do not correspond to the correct conversion of 7 inches to centimeters.

4. Classifications of human tissues exclude:

• A. Epithelial tissue
• B. Nervous tissue
• C. Adipose tissue (a specialized form of connective tissue)
• D. Bony tissue

Correct answer: D

Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.

5. Reread the following sentence from the passage: 'Don't hit me with arguments about greater freedom for workers.' Which of the following would be a more formal way to rewrite the sentence?

• A. I disagree with the argument about contract workers having greater freedom.
• B. Stop telling me that freelancers have more freedom!
• C. Is there actually freedom for workers?
• D. I've already heard.

Correct answer: A

Rationale: Choice A, 'I disagree with the argument about contract workers having greater freedom,' is the correct answer. This sentence rephrases the original statement in a more formal and respectful tone, which is suitable for formal writing. Choice B is too direct and lacks formality. Choice C does not address the argument directly and poses a question instead of providing a formal statement. Choice D is dismissive and does not offer a formal rewrite of the original sentence.
