TOEFL Practice Test #5 2

Question 1

A reading passage about astronomy states: "The Hubble constant quantifies the rate at which the universe is expanding, though measurements using different methods have yielded discrepant values." The word "discrepant" means:

Accepted Answer

Showing inconsistency or disagreement between measurements

Answer

"Discrepant" describes findings that are inconsistent with each other or with an expected value. In science, discrepant measurements indicate unresolved methodological issues or gaps in understanding—here, different measurement methods produce values that do not agree with each other.

Question 2

In a TOEFL Listening lecture, a professor of economics explains elasticity of demand. She says: "If the price of insulin doubles, diabetic patients will still buy it—they have no choice." This example illustrates:

Accepted Answer

Inelastic demand — quantity demanded does not change significantly with price

Answer

Inelastic demand describes a situation where quantity demanded changes little when price changes, because the product is a necessity with no substitute. Insulin for diabetics is the classic example: patients must buy it regardless of price, making demand highly inelastic.

Question 3

A TOEFL Reading passage includes this sentence: "Despite extensive excavation, archaeologists have found no evidence of fortifications at the site, suggesting that the settlement was either peaceful or protected by geography rather than defensive walls." The word "fortifications" means:

Accepted Answer

Defensive structures built to protect a settlement

Answer

"Fortifications" are defensive structures—walls, ramparts, moats—built to protect a settlement from attack. The context clues ("no evidence," "defensive walls," "peaceful or protected") confirm this meaning.

Question 4

In the TOEFL Writing section, what is the recommended length for the Independent Writing Task essay?

Accepted Answer

At least 300 words, ideally 400–500 words

Answer

ETS recommends at least 300 words for the Independent Writing Task, but well-developed essays typically range from 400–500 words. Length alone does not determine the score—development, coherence, and language use matter—but very short responses indicate underdevelopment.

Question 5

A TOEFL Reading "Category Chart" question presents a table and asks students to classify concepts from the passage into two or more categories. What skill does this question type primarily test?

Accepted Answer

Ability to recognize how information in the passage is organized into distinct categories

Answer

Category Chart (Schematic Table) questions test the ability to organize and classify information from the passage. Students must sort key concepts, examples, or features into the correct categories, demonstrating comprehension of how the author has distinguished and grouped information.
