1. Which of the following statements would be LEAST relevant in a formal essay about artist Salvador Dalí?

• A. Although his works are famed for their dream-like qualities, Dalí executed them with realism reminiscent of the Renaissance masters.
• B. Salvador Dalí’s eccentricity extended beyond his artwork, affecting the strange public persona he created, which can be witnessed in his numerous television appearances.
• C. I’ve always found Dalí’s painting The Persistence of Memory to be really disturbing for some reason.
• D. Although Salvador Dalí is best known for his paintings, he also was active in cinema and collaborated with such filmmakers as Luis Bunuel and Alfred Hitchcock.

Correct answer: C

Rationale: Option C is subjective and personal, making it less suitable for a formal essay about Salvador Dalí. In formal writing, it is important to maintain objectivity and focus on factual information rather than personal opinions. Choices A, B, and D provide relevant information about Dalí, his artwork, and his collaborations, which are more appropriate for inclusion in a formal essay.

2. Which of the following is a true statement about dominance in genetics?

• A. All genes adhere to Mendel’s law of dominance.
• B. A dominant allele will always be expressed.
• C. When two dominant alleles are present, the resulting phenotype will express both traits.
• D. There are three or more alleles possible for all genes.

Correct answer: B

Rationale: In genetics, dominance refers to the relationship between two different alleles of a gene where one allele (dominant) masks the expression of another allele (recessive) in an individual's phenotype. The correct statement about dominance is that a dominant allele will always be expressed in the phenotype, even in the presence of a recessive allele. This means that if an individual has at least one dominant allele for a particular trait, that trait will be expressed. Choice A is incorrect because not all genes follow Mendel’s law of dominance; exceptions do exist. Choice C is incorrect because when two dominant alleles are present, only one will be expressed due to complete dominance. Choice D is incorrect as there can be more than three alleles for a gene, and not all genes have three or more alleles.

3. A book has a width of 2.5 decimeters. What is the width of the book in centimeters?

• A. 0.25 centimeters
• B. 25 centimeters
• C. 250 centimeters
• D. 0.025 centimeters

Correct answer: B

Rationale: To convert decimeters to centimeters, we use the conversion factor that 1 decimeter is equal to 10 centimeters. Setting up the proportion: 1/0.1 = x/2.5. Solving for x gives 2.5 = 0.1x, x = 25. Therefore, the width of the book in centimeters is 25. Choices A, C, and D are incorrect because they do not correctly convert decimeters to centimeters. A and D have decimal placement errors, and C has an incorrect magnitude of centimeters.

4. Which term refers to the relaxation of the heart muscle?

• A. Diastole
• B. Systole
• C. Asystole
• D. Cardiastole

Correct answer: A

Rationale: The correct answer is A: Diastole. Diastole is the phase of the heartbeat when the heart muscle relaxes, allowing the chambers to fill with blood. Systole, on the other hand, refers to the contraction phase of the heart when it pumps blood out. Asystole is the absence of heart contractions, often referred to as cardiac arrest. Cardiastole is not a recognized medical term in relation to heart muscle relaxation, making it an incorrect choice.

5. Which of the following algebraic equations correctly represents the sentence 'Four more than a number, x, is 2 less than 1/3 of another number, y'?

• A. x + 4 = (1/3)y - 2
• B. 4x = 2 - (1/3)y
• C. 4 - x = 2 + (1/3)y
• D. x + 4 = 2 - (1/3)y

Correct answer: A

Rationale: To represent 'Four more than a number, x', we write x + 4. This is equal to '2 less than 1/3 of another number, y', which translates to 1/3y - 2. Therefore, the correct equation is x + 4 = (1/3)y - 2. Choice B is incorrect as it incorrectly combines the values of x and y. Choice C is incorrect as it doesn't properly relate x and y with the given conditions. Choice D is incorrect as it doesn't correctly represent the relationship between x and y according to the given statement.
