Here are the official solutions:
Q1. Based on the information in the passage, which of the following could be an example of an activity that results in negative externalities?
Correct Answer:
E. A company introduces a new type of pesticide that increases crop yields but also contaminates nearby water sources.
This is a classic negative externality: the company benefits from increased yields, but the water contamination harms others.
Incorrect Answers:
A. A company launches a new product that significantly reduces the cost of energy for consumers.
This is a direct benefit with no harm to third parties.
B. A homeowner installs solar panels on their roof, reducing their electricity costs.
This results in a direct benefit with no harm to others.
C. A tech company develops an app that increases worker productivity, allowing businesses to reduce costs.
Increased productivity benefits businesses directly, with no negative effects on third parties.
D. A public park increases its entrance fee, which leads to a reduction in visitor numbers.
This action does not have unintended harmful consequences affecting others.
Q2. Based on the information in the passage, it can be inferred that governments are most likely to intervene in the economy when:
Correct Answer:
A. Externalities result in significant differences between private and social costs.
The passage states that externalities are among the main reasons for government intervention, especially when private and social costs diverge.
Incorrect Answers:
B. Consumers are able to influence the price of goods based on supply and demand.
This is unrelated to the concept of externalities discussed in the passage.
C. The production opportunities for firms are optimized without affecting others.
If there are no negative effects on others, government intervention is less likely.
D. The benefits of production are fully absorbed by those directly involved in the transactions.
This suggests no externalities are present, reducing the need for intervention.
E. Firms efficiently incorporate the costs of negative externalities into their pricing.
If firms incorporate these costs, there's no need for government intervention.
Q3. The primary purpose of the passage is to:
Correct Answer:
B. Explain the concept of externalities and how they justify government intervention in economic activities.
The passage primarily focuses on explaining externalities, particularly how they lead to government intervention when private and social costs diverge.
Incorrect Answers:
A. Criticize the role of businesses in creating externalities and suggest ways to mitigate them.
The passage does not criticize businesses or provide solutions, but rather explains the concept of externalities.
C. Propose a framework for understanding the impact of government policies on private businesses.
The passage discusses externalities and government intervention but does not propose a specific framework.
D. Analyze the trade-offs between private profit maximization and societal welfare in market transactions.
While there’s mention of private and social costs, the passage's goal is not to deeply analyze these trade-offs.
E. Compare different types of externalities and their respective impact on economic production and consumption.
The passage primarily explains negative externalities like pollution rather than comparing various types of externalities.
