Trade and Opportunity Costs
This passage and table describe the opportunity costs faced by two countries.
1 The countries of Grand Coast and Toland are trading partners. The two main goods
traded are timber and fish. Every year the ministers of trade from each country
attend an international conference to discuss issues related to foreign trade and
decide how each country should specialize. The table provides economic data for
one year.
In Grand Coast, what is the opportunity cost of one unit of fish?
- A. ½ unit of timber
- B. 5 units of timber
- C. 2 units of fish
- D. 8 units of fish
Correct Answer & Rationale
Correct Answer: A
Opportunity cost refers to the value of the next best alternative that is forgone when making a choice. In Grand Coast, if one unit of fish is produced, the opportunity cost is the amount of timber that could have been produced instead. Option A, ½ unit of timber, accurately reflects this trade-off, indicating that for each unit of fish, only half a unit of timber is sacrificed. Option B, 5 units of timber, overestimates the sacrifice, suggesting a much higher cost than what is actually incurred. Option C, 2 units of fish, misinterprets the concept, as it implies a cost in the same product rather than in timber. Option D, 8 units of fish, also incorrectly suggests a loss of the same good, failing to recognize the opportunity cost in terms of timber.

What does it mean if a bank's advertisement for a certificate of deposit (CD) indicates a 4% APY?
- A. The CD matures at the rate of 4% each year.
- B. Only 4% of the CD's value can be withdrawn in any given year.
- C. You will pay 4% of the CD's value each year in service fees.
- D. The CD will earn 4% interest each year that is then added to the CD's balance.
Correct Answer & Rationale
Correct Answer: D
An advertisement indicating a 4% APY (Annual Percentage Yield) signifies that the CD will earn 4% interest annually, which is compounded and added to the CD's balance. Option A misinterprets APY; it does not refer to maturity but to interest earnings. Option B incorrectly suggests a withdrawal limit based on a percentage, which is not how CDs function. Option C mistakenly implies that there are service fees amounting to 4%, which is unrelated to APY. Understanding APY is crucial for evaluating the growth potential of a CD investment.

After the Revolutionary War, the western border of the United States was the
- A. Mississippi River.
- B. Gulf of Mexico.
- C. Rocky Mountains.
- D. Great Lakes.
Correct Answer & Rationale
Correct Answer: A
The western border of the United States after the Revolutionary War was defined by the Mississippi River, which served as a natural boundary facilitating westward expansion. Option B, the Gulf of Mexico, is incorrect as it is located to the south, not marking the western border. Option C, the Rocky Mountains, is also inaccurate; while they are a significant geographical feature, they were not recognized as a border at that time. Option D, the Great Lakes, pertains to the northern boundary and does not represent the western limit. Thus, the Mississippi River accurately reflects the western boundary post-war.

The purpose of these five amendments is to
- A. help the government operate efficiently.
- B. help people know how to be good citizens.
- C. protect citizens from criminals.
- D. protect citizens from the government.
Correct Answer & Rationale
Correct Answer: D
The five amendments in question primarily aim to safeguard individual rights against potential government overreach. They establish limits on governmental power, ensuring that citizens retain personal freedoms and legal protections. Option A is incorrect as these amendments focus on individual rights rather than government efficiency. Option B misinterprets the primary intent; while good citizenship is important, the amendments do not serve as a guide for civic behavior. Option C is also misleading, as the amendments are designed to protect citizens from government actions, not criminal activities. Thus, the focus remains on limiting government power to ensure personal liberties.

Why were most of the passengers denied permission to enter Cuba?
- A. Cuba had already accepted all the refugees it could for that year.
- B. Cuba and Germany did not have diplomatic relations at that time.
- C. Cuba's president claimed their documents had been obtained illegally.
- D. It was feared that admitting them would create tension with Germany.
Correct Answer & Rationale
Correct Answer: C
Most passengers were denied entry because Cuba's president claimed their documents had been obtained illegally. This assertion directly impacted the legitimacy of their entry, making it a crucial reason for their denial. Option A is incorrect as it implies a quota issue rather than a legal matter. Option B is misleading; while diplomatic relations may affect policies, they were not the primary reason for the denial in this context. Option D suggests geopolitical concerns, but the immediate issue was the legality of the passengers’ documentation, which was the decisive factor in their rejection.
