LSAT Main Point and Primary Purpose 2 â Questions and Answers
Question 1: A passage argues that urban heat islands are worsening due to reduced green space, then proposes mandatory tree-planting ordinances as a remedy. What is the primary purpose of this passage?
- To explain the history of urban planning
- To advocate for a policy solution to a documented environmental problem (Correct answer)
- To compare temperatures across different cities
- To critique existing environmental regulations
Correct answer: To advocate for a policy solution to a documented environmental problem
The passage identifies a problem (urban heat islands) and argues for a specific policy remedy (tree-planting ordinances), making advocacy for that solution its primary purpose.
Question 2: When a Reading Comprehension passage presents multiple viewpoints on a controversy and then explicitly endorses one, the main point is most likely:
- A neutral summary of all viewpoints presented
- The author's preferred position among those debated (Correct answer)
- The most extreme position in the debate
- The historical background of the controversy
Correct answer: The author's preferred position among those debated
When an author presents competing views and then endorses one, that endorsed position constitutes the main point of the passage.
Question 3: A Logical Reasoning argument concludes: 'Therefore, the city should not build the new stadium.' This conclusion is best described as:
- A piece of background information
- The main point the argument is designed to establish (Correct answer)
- A premise supporting a broader claim
- An example illustrating a general principle
Correct answer: The main point the argument is designed to establish
In Logical Reasoning, the conclusionâsignaled by 'therefore'âis the main point the argument's premises are intended to support.
Question 4: An author spends the first paragraph describing a scientific puzzle, the second presenting two competing hypotheses, and the final paragraph explaining why one hypothesis better fits the data. The primary purpose is to:
- Summarize the history of a scientific field
- Argue that one hypothesis better explains the available evidence (Correct answer)
- Describe experimental methods used by researchers
- Identify flaws in both competing hypotheses
Correct answer: Argue that one hypothesis better explains the available evidence
The structureâpuzzle, competing explanations, evaluationâculminates in the author arguing that one hypothesis is superior, which is the primary purpose.
Question 5: Which of the following most accurately expresses the main point of an argument that states: 'Since all mammals are warm-blooded and dolphins are mammals, dolphins must be warm-blooded'?
- All warm-blooded animals are mammals
- Dolphins share characteristics with other marine animals
- Dolphins are warm-blooded because they are mammals (Correct answer)
- Mammals are defined by their aquatic habitat
Correct answer: Dolphins are warm-blooded because they are mammals
The conclusion drawn from the premisesâthat dolphins are warm-bloodedâis the main point of this syllogistic argument.
Question 6: A passage criticizes a popular diet trend by examining its scientific basis, surveying contrary studies, and concluding that its benefits are overstated. The primary purpose is to:
- Recommend an alternative diet to readers
- Challenge the scientific credibility of a popular dietary claim (Correct answer)
- Explain the nutritional needs of the average person
- Praise researchers who studied the diet trend
Correct answer: Challenge the scientific credibility of a popular dietary claim
The passage systematically dismantles the scientific basis of the diet trend, making its primary purpose one of critical challenge.
Question 7: On the LSAT, a question asks: 'Which one of the following most accurately expresses the main point of the argument?' The best answer will:
- Restate a premise verbatim from the stimulus
- Capture the conclusion the premises are meant to support (Correct answer)
- Introduce new information not found in the stimulus
- Describe the method of reasoning used in the argument
Correct answer: Capture the conclusion the premises are meant to support
Main point questions require identifying the conclusionâthe claim the premises supportânot restating premises or adding new information.
