1. What type of intermolecular force is responsible for the high surface tension of water?

• A. Hydrogen bonding
• B. London dispersion forces
• C. Ionic bonding
• D. Metallic bonding

Correct answer: A

Rationale: The high surface tension of water is primarily due to the strong hydrogen bonding between water molecules. Hydrogen bonding is a specific type of intermolecular force that occurs between a hydrogen atom covalently bonded to a highly electronegative atom, like oxygen in water, and another electronegative atom nearby. This unique interaction results in a strong attraction between water molecules at the surface, leading to the cohesive forces responsible for the high surface tension of water. Choices B, C, and D are incorrect because London dispersion forces, ionic bonding, and metallic bonding do not account for the high surface tension observed in water. London dispersion forces are relatively weaker intermolecular forces, while ionic and metallic bonding are types of intramolecular forces that do not directly contribute to the surface tension of water.

2. Which of the following terms describes stem cells that have the ability to develop into any cell found in the human body?

• A. Totipotent stem cells
• B. Multipotent stem cells
• C. Pluripotent stem cells
• D. Hematopoietic stem cells

Correct answer: A

Rationale: Totipotent stem cells have the unique ability to differentiate into any cell type in the human body and can generate a complete organism. They are considered the most versatile type of stem cells, capable of developing into all cell types, including extraembryonic tissues. Choice A, Totipotent stem cells, is the correct answer as it specifically describes stem cells with the broadest differentiation potential. Choice B, Multipotent stem cells, refers to stem cells that can differentiate into a limited range of cell types. Choice C, Pluripotent stem cells, can give rise to almost all cell types, but not the complete organism like totipotent stem cells. Choice D, Hematopoietic stem cells, are a type of multipotent stem cells that give rise to various blood cell types, but do not have the same broad differentiation potential as totipotent stem cells.

3. “His ego was as big as the tallest mountain.” This sentence is an example of which figure of speech?

• A. Hyperbole
• B. Idiom
• C. Simile
• D. Metaphor

Correct answer: C

Rationale: This sentence is an example of a simile because it compares 'his ego' to 'the tallest mountain' using the word 'as.' Similes use 'like' or 'as' to create a comparison, which is the case here. A metaphor, on the other hand, does not use 'like' or 'as' but instead states that one thing is another. Hyperbole involves exaggerated statements not meant to be taken literally, while idioms are expressions that have a figurative meaning different from the literal interpretation. Therefore, the correct answer is 'C: Simile.'

4. A couple dining at a restaurant receives a bill for $28.40. They wish to leave a 10% tip. Which of the following is the estimated gratuity?

• A. $4.00
• B. $6.00
• C. $2.50
• D. $3.00

Correct answer: D

Rationale: To calculate a 10% tip on a bill of $28.40, you would first find 10% of $28.40, which is $2.84. Since you typically round up when leaving a tip, the estimated gratuity would be $3.00. Option A is incorrect as it is too high for a 10% tip. Option B is incorrect as it is too high. Option C is incorrect as it is too low for a 10% tip. Therefore, the correct answer is $3.00.

5. Does the author imply that she believes the hero should be more nuanced and less unconditionally good in U.S.-made movies?

• A. believes the hero should always appear to be morally worthy.
• B. believes the hero should never appear to be morally worthy.
• C. believes the hero should be more nuanced and less unconditionally good.
• D. believes the hero is an uninteresting character.

Correct answer: C

Rationale: The author implies that she believes the hero should be more nuanced and less unconditionally good in U.S.-made movies. This is evident from her claim that it is hard to find a movie that presents the hero as anything other than supremely morally worthy, suggesting a desire for more complexity and depth in the portrayal of the hero character. Choice A is incorrect because the author does not advocate for the hero always appearing morally worthy. Choice B is incorrect as the author does not suggest that the hero should never appear morally worthy. Choice D is incorrect as the author does not state that the hero is an uninteresting character, but rather emphasizes the need for a more nuanced portrayal.
