1. Which of the following has a smaller genetic scale than a chromosome?

• A. Genome
• B. Gene
• C. DNA
• D. All of the above

Correct answer: B

Rationale: The correct answer is 'B: Gene.' A gene is a segment of DNA and is smaller in scale than a chromosome. Genes are the fundamental units of heredity, containing the instructions for building and maintaining an organism. While a chromosome is a larger structure that carries many genes, each gene is a specific segment of DNA responsible for encoding a particular protein or RNA molecule. Choices A, C, and D are incorrect. The 'Genome' (Choice A) refers to the complete set of an organism's genetic material, including all of its genes, while 'DNA' (Choice C) is the molecule that carries the genetic instructions. 'All of the above' (Choice D) is incorrect because not all options have a smaller genetic scale than a chromosome.

2. What is the law that states energy can neither be created nor destroyed?

• A. Law of Conservation of Matter
• B. Law of Conservation of Energy
• C. Law of Universal Gravitation
• D. Law of Inertia

Correct answer: B

Rationale: The correct answer is the Law of Conservation of Energy. This law states that energy cannot be created or destroyed, only transformed from one form to another. The Law of Conservation of Matter (Choice A) is related to mass and the preservation of mass in a closed system, not energy. The Law of Universal Gravitation (Choice C) describes the force of attraction between objects with mass. The Law of Inertia (Choice D) states that an object will remain at rest or in uniform motion unless acted upon by an external force.

3. 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.

4. Which of the following is not an example of something that the author of Passage 1 states might be found in a fairy tale?

• A. Trolls
• B. Witches
• C. Talking animals
• D. Giants

Correct answer: B

Rationale: The author of Passage 1 mentions trolls, elves, giants, and talking animals as examples of imaginary creatures found in fairy tales. However, witches are not specifically mentioned. Therefore, witches are not an example of something the author states might be found in a fairy tale in Passage 1. Choice B is the correct answer. Choice A, trolls, Choice C, talking animals, and Choice D, giants, are all examples provided by the author in the passage, making them incorrect answers.

5. Which gland produces the hormone responsible for the 'fight-or-flight' response in stressful situations?

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pancreas

Correct answer: C

Rationale: The correct answer is C: Adrenal gland. The hormone responsible for the 'fight-or-flight' response in stressful situations is produced by the adrenal gland. This hormone is called adrenaline (epinephrine) and is released in response to stress, preparing the body to either fight the stressor or flee from it. The other choices are incorrect because the thyroid gland primarily produces hormones that regulate metabolism, the pituitary gland produces various hormones that control other endocrine glands, and the pancreas produces insulin and glucagon to regulate blood sugar levels.
