TOEFL Practice Test #4 2 — Questions and Answers
Question 1: A passage about ancient Roman engineering reads: "The Romans' sophisticated understanding of hydraulics enabled them to construct aqueducts that transported water across vast distances with remarkable precision." The phrase "remarkable precision" suggests:
- The Romans made many errors in their engineering designs.
- The aqueducts were admired primarily for their artistic beauty.
- The engineering was highly accurate and technically impressive for the era. (Correct answer)
- Roman aqueducts were designed by Greek engineers.
Correct answer: The engineering was highly accurate and technically impressive for the era.
"Remarkable precision" is a phrase expressing admiration for the technical accuracy of the engineering. In context, it reinforces the claim about "sophisticated understanding"—both signal that Roman hydraulic engineering achieved an impressive level of accuracy that was notable, especially for the ancient world.
Question 2: In a TOEFL Listening lecture on art history, a professor discusses how Impressionist painters broke from academic tradition. The professor says: "They were essentially dismissed by the establishment—yet today their work commands millions at auction." This statement serves what rhetorical purpose?
- To argue that academic art is overvalued
- To illustrate the irony between initial rejection and eventual prestige (Correct answer)
- To provide financial data on the art market
- To suggest that Impressionism is the most important art movement
Correct answer: To illustrate the irony between initial rejection and eventual prestige
The contrast between early dismissal and current financial prestige creates a powerful irony that the professor uses rhetorically to highlight how artistic establishment judgments can be reversed over time. This is a function/purpose question testing understanding of why a speaker makes a specific statement.
Question 3: A TOEFL Reading passage discusses ocean acidification. Paragraph 3 states: "As atmospheric CO2 dissolves into seawater, carbonic acid is formed, lowering the pH of the ocean." Which is the best sentence simplification of this statement?
- The ocean becomes more basic as CO2 increases.
- CO2 in the atmosphere has no effect on ocean chemistry.
- When CO2 enters seawater, it creates acid, making the ocean more acidic. (Correct answer)
- Ocean pH is unaffected by changes in atmospheric composition.
Correct answer: When CO2 enters seawater, it creates acid, making the ocean more acidic.
Sentence simplification questions require students to choose an answer that contains the essential meaning of the original without changing it. Option C accurately captures the core process: CO2 + seawater → carbonic acid → lower pH (more acidic), without distortion or omission.
Question 4: A TOEFL Independent Writing task asks: "Is it better to have one career throughout your life or to change careers several times?" Which thesis most effectively sets up a well-organized essay?
- Many people today change careers, and this is very different from the past.
- Career decisions are personal and depend on individual circumstances.
- Although career stability offers security and mastery, changing careers allows individuals to adapt to evolving opportunities and develop a broader range of skills. (Correct answer)
- I think people should do whatever makes them happiest in life.
Correct answer: Although career stability offers security and mastery, changing careers allows individuals to adapt to evolving opportunities and develop a broader range of skills.
A strong thesis takes a clear argumentative stance and previews the essay's structure. Option C acknowledges both sides (concession + main argument) and specifies two concrete reasons for career changes. This allows the writer to organize a coherent, well-developed essay.
Question 5: In the TOEFL Listening section, you hear two students discussing a professor's optional review session. One student is enthusiastic; the other is ambivalent. A question asks: "What does the woman suggest about attending the review session?" This is which question type?
- Gist-content question
- Speaker purpose question
- Connecting content question
- Detail question about the woman's opinion (Correct answer)
Correct answer: Detail question about the woman's opinion
Questions asking what a specific speaker "suggests" or "says about" a topic are detail or content questions focusing on one speaker's stated position or suggestion. This requires identifying the specific information or opinion the woman expresses during the conversation.
Question 6: A reading passage describes the "tragedy of the commons"—the depletion of a shared resource when individuals act in self-interest. The passage then uses the example of overfishing in international waters. What rhetorical purpose does this example serve?
- To argue that international law should regulate all fishing practices
- To illustrate how the abstract economic concept operates in a real-world context (Correct answer)
- To demonstrate that overfishing is the most serious environmental problem
- To compare different countries' fishing practices
Correct answer: To illustrate how the abstract economic concept operates in a real-world context
Examples in academic passages serve to make abstract theories concrete and understandable. The overfishing example takes the theoretical "tragedy of the commons" concept and shows how it plays out in an actual, observable situation—its rhetorical purpose is illustration, not argumentation.
