TOEFL Reading: Rhetorical Purpose Questions Questions and Answers 3 — Questions and Answers
Question 1: A TOEFL Reading passage about the history of science discusses how scientists initially rejected Wegener's theory of continental drift. The author describes the community's skepticism in detail. The rhetorical purpose is most likely to:
- Argue that scientists are always resistant to new ideas
- Illustrate how established scientific paradigms can impede the acceptance of revolutionary theories (Correct answer)
- Provide a biography of Alfred Wegener's professional struggles
- Compare Wegener's theory to modern plate tectonics
Correct answer: Illustrate how established scientific paradigms can impede the acceptance of revolutionary theories
By describing the scientific community's rejection of continental drift, the author illustrates how entrenched paradigms resist paradigm shifts—a key concept from the philosophy of science. The purpose is to make an abstract claim about scientific progress concrete through a historical example.
Question 2: In a TOEFL Reading passage, a paragraph opens with: "Consider the following scenario: a forest fire devastates an old-growth forest." The rhetorical purpose of this sentence is to:
- State the author's main thesis about forest management
- Introduce a hypothetical scenario to help readers engage with and understand the concept being discussed (Correct answer)
- Describe a real historical forest fire as evidence
- Define the term "old-growth forest" for the reader
Correct answer: Introduce a hypothetical scenario to help readers engage with and understand the concept being discussed
"Consider the following scenario" explicitly invites the reader into a thought experiment. This rhetorical move is used to make abstract ecological or scientific concepts more tangible by imagining a specific situation. It engages the reader and provides a context for understanding the following explanation.
Question 3: A passage about industrial agriculture states: "Critics of this approach argue that monoculture farming depletes soil nutrients and increases vulnerability to pests." The rhetorical purpose of this sentence is to:
- Present the author's personal view on industrial agriculture
- Introduce a counterargument that the author will then address or refute (Correct answer)
- Summarize the overall argument of the passage
- Provide statistical data about soil depletion rates
Correct answer: Introduce a counterargument that the author will then address or refute
The phrase "critics argue" signals that the author is presenting an opposing view or counterargument. This rhetorical move either sets up a refutation (the author will counter this) or a balanced presentation of multiple perspectives. It is the classic structure of academic counterargument acknowledgment.
Question 4: In a passage on language acquisition, the author writes a paragraph describing how infants babble before producing recognizable words. The question asks why the author describes infant babbling. The most likely purpose is:
- To define the term "babbling" for readers unfamiliar with linguistics
- To illustrate the developmental progression from prelinguistic vocalization to language—supporting a claim about how language acquisition occurs in stages (Correct answer)
- To argue that babbling delays are a sign of developmental problems
- To compare babbling in human infants with vocalizations in other primates
Correct answer: To illustrate the developmental progression from prelinguistic vocalization to language—supporting a claim about how language acquisition occurs in stages
The description of infant babbling serves as developmental evidence supporting the claim that language acquisition is staged and sequential. The babbling stage precedes word production, illustrating that language emerges gradually—the rhetorical purpose is to provide developmental evidence for a theoretical claim about staged acquisition.
Question 5: A passage on economics discusses "creative destruction"—the process by which new industries replace obsolete ones. The author then describes how the automobile industry replaced the horse-drawn carriage industry. The rhetorical purpose of this historical example is to:
- Argue that horse-drawn carriages were inferior products
- Demonstrate creative destruction in action using a well-known historical case that readers can easily understand (Correct answer)
- Compare the economic impact of the automobile with modern digital disruption
- Provide a timeline of transportation technology development
Correct answer: Demonstrate creative destruction in action using a well-known historical case that readers can easily understand
Historical examples serve to make abstract economic concepts concrete. The horse-carriage-to-automobile transition is an iconic, universally recognizable example of creative destruction—industries displaced by new technology. The rhetorical purpose is to illustrate and validate the abstract concept with a clear, memorable case.
Question 6: A TOEFL Reading passage includes the sentence: "Importantly, this mechanism is not unique to mammals; similar processes have been observed in insects and even single-celled organisms." The word "importantly" signals that this sentence:
- Introduces an exception that undermines the preceding argument
- Emphasizes a significant extension of the preceding claim—broadening its scope to multiple organism types (Correct answer)
- Provides a definition of the mechanism described earlier
- Signals a transition to a discussion of a different topic
Correct answer: Emphasizes a significant extension of the preceding claim—broadening its scope to multiple organism types
"Importantly" is a sentence adverb used to flag information the author considers particularly significant. Here, it signals that the widespread occurrence of this mechanism across diverse organisms is a key point—it extends and strengthens the preceding argument by demonstrating evolutionary universality.
