1. Which organizational style is used in the following passage? 'There are several reasons why the new student café has not been as successful as expected. One factor is that prices are higher than originally advertised, so many students cannot afford to buy food and beverages there.'

• A. Cause and effect order
• B. Compare and contrast order
• C. Spatial order
• D. Time order

Correct answer: A

Rationale: The correct organizational style used in the passage is cause and effect order. It explains the reasons (causes) why the new student café has not been successful, specifically mentioning that the higher prices lead to students being unable to afford food and beverages (effect). The passage clearly establishes a relationship between a situation (high prices) and its consequences (students not able to buy), making it a classic example of cause and effect. Choice B (Compare and contrast order) is incorrect as the passage does not present a comparison or a contrast between two or more items or situations. Choice C (Spatial order) is incorrect as it refers to organizing information based on physical location or direction, which is not applicable in this context. Choice D (Time order) is also incorrect as it involves organizing information based on a sequence of events over time, which is not the primary focus of the passage.

2. If Hannah spends at least $16 on 4 packages of coffee, which of the following inequalities represents the possible costs?

• A. 16 ≥ 4p
• B. 16 < 4p
• C. 16 > 4p
• D. 16 ≤ 4p

Correct answer: D

Rationale: To represent the relationship between the number of packages of coffee and the minimum cost, the inequality can be written as 4p ≥ 16 (cost is at least $16). This inequality can also be expressed as 16 ≤ 4p, which reads as the cost being less than or equal to $16. Therefore, the correct answer is D. Choice A (16 ≥ 4p) implies that the cost can be greater than or equal to $16, which does not align with the statement that Hannah spends at least $16. Choice B (16 < 4p) suggests that the cost is less than $16, which contradicts the given information. Choice C (16 > 4p) indicates that the cost is greater than $16, which is not accurate based on the scenario provided.

3. What is the definition of work in physics?

• A. Force applied to an object at rest
• B. Force exerted by an object in motion
• C. Transfer of energy through motion along a direction
• D. Measure of an object's potential energy

Correct answer: C

Rationale: In physics, work is defined as the transfer of energy through motion along a direction. When a force is applied to an object, and the object moves in the direction of the force, work is done on the object. The work done is calculated as the force applied multiplied by the distance the object moves in the direction of the force. Choices A and B do not fully capture the essence of work, as work is about energy transfer through motion, not merely applying force to objects at rest or in motion. Choice D is incorrect as work is not a measure of an object's potential energy; rather, it is the transfer of energy through motion.

4. What is a group of organisms of the same species living in a particular area called?

• A. Community
• B. Population
• C. Ecosystem
• D. Habitat

Correct answer: B

Rationale: A) Community refers to all the populations of different species living and interacting in a particular area. Since the question specifies organisms of the same species, community is not the correct answer. B) Population is a group of organisms of the same species living in a particular area. This term specifically refers to individuals of the same species and their interactions within a defined area. C) Ecosystem includes all the living organisms (biotic factors) and non-living components (abiotic factors) in a particular area and their interactions. While populations are part of an ecosystem, the term 'ecosystem' is broader and includes multiple populations. D) Habitat refers to the specific environment where an organism lives, including the physical and biological factors. It is the place where a population or individual organism resides, but it does not specifically refer to a group of organisms of the same species.

5. What is the purpose of sodium bicarbonate when released into the lumen of the small intestine?

• A. It works to chemically digest fats in the chyme.
• B. It decreases the pH of the chyme to prevent harm to the intestine.
• C. It works to chemically digest proteins in the chyme.
• D. It increases the pH of the chyme to prevent harm to the intestine.

Correct answer: D

Rationale: Sodium bicarbonate, when released into the lumen of the small intestine, functions to increase the pH of the acidic chyme coming from the stomach. This increase in pH helps neutralize the acidity of the chyme, creating a more optimal environment for the digestive enzymes in the small intestine to function properly. Maintaining a slightly basic pH in the small intestine is crucial for overall digestion and absorption of nutrients. Choices A, B, and C are incorrect. Sodium bicarbonate does not chemically digest fats or proteins in the chyme, and it does not decrease the pH of the chyme as it actually increases the pH to prevent harm to the intestine.
