Reading Comprehension Main Idea and Primary Purpose 2 — Questions and Answers
Question 1: A passage discusses how migratory birds navigate using the Earth's magnetic field, the position of stars, and landmarks. The author also notes that light pollution from cities disrupts these navigation methods. What is the primary purpose?
- To argue that all cities should turn off their lights at night
- To explain how migratory birds navigate and how human activity interferes with this ability (Correct answer)
- To describe the beauty of bird migration
- To compare different bird species
Correct answer: To explain how migratory birds navigate and how human activity interferes with this ability
The passage combines explanation (how birds navigate) with a problem (light pollution disrupting navigation), making its primary purpose to inform about bird navigation and the human impact on it.
The primary purpose encompasses the full scope of the passage. It first explains navigation methods (magnetic field, stars, landmarks) and then identifies a human-caused problem (light pollution). The purpose is informational and analytical — explaining both the natural process and the interference. It doesn't argue for specific action (A), focus on aesthetics (C), or compare species (D).
Question 2: An author writes a book review that summarizes the plot, evaluates the writing style, and recommends the book for fans of historical fiction. What is the primary purpose?
- To retell the entire story in detail
- To evaluate a book and guide potential readers in their decision (Correct answer)
- To criticize the publishing industry
- To teach readers how to write historical fiction
Correct answer: To evaluate a book and guide potential readers in their decision
A book review that summarizes, evaluates, and recommends serves the primary purpose of helping readers decide whether to read the book — it's evaluative and advisory.
Book reviews serve a dual purpose: evaluation and guidance. The summary provides context, the style evaluation offers critical analysis, and the recommendation directs specific readers. Together, these elements help potential readers make informed decisions. The primary purpose isn't to retell the story completely (A), critique the industry (C), or teach writing (D) — it's to evaluate the specific book and advise readers.
Question 3: A passage describes how a family gathered for a grandmother's 90th birthday, shared stories about her life, and presented her with a scrapbook of family photos spanning seven decades. What is the main idea?
- Birthday parties should include scrapbooks
- The family came together to celebrate and honor the grandmother's long life and legacy (Correct answer)
- The grandmother is 90 years old
- Family photos are important historical documents
Correct answer: The family came together to celebrate and honor the grandmother's long life and legacy
The gathering, storytelling, and scrapbook all serve one purpose: celebrating and honoring the grandmother, making this the main idea of the passage.
Every detail supports the central theme of celebration and honor: the family gathered (showing they value her), shared stories about her life (honoring her experiences), and presented a scrapbook spanning seven decades (preserving her legacy). The main idea isn't a prescriptive statement about parties (A), a simple fact about her age (C), or a claim about photo documentation (D). It's about the family's collective act of celebrating this woman's life.
Question 4: A news article reports that a tech company has laid off 10% of its workforce, closed two regional offices, and shifted resources to artificial intelligence development. What is the main idea?
- The tech industry is completely collapsing
- Artificial intelligence will replace all human workers
- The company is restructuring its operations to prioritize AI development (Correct answer)
- Layoffs are always a sign of poor management
Correct answer: The company is restructuring its operations to prioritize AI development
The layoffs, office closures, and resource shift to AI are all parts of a strategic restructuring — the main idea is that the company is reorganizing to focus on AI.
Three corporate actions are described: workforce reduction, facility closures, and resource reallocation to AI. These are components of a single strategic restructuring. The main idea connects them: the company is reorganizing to prioritize AI. Option A wildly overgeneralizes from one company. Option B makes an absolute prediction not supported by the passage. Option D makes a judgmental claim not in the text. Only C accurately captures the restructuring narrative.
Question 5: A passage explains how to prepare a garden bed: clearing debris, testing soil pH, adding amendments, and creating proper drainage. What is the primary purpose?
- To persuade readers to start gardening
- To provide step-by-step instructions for preparing a garden bed (Correct answer)
- To compare different gardening methods
- To describe the author's personal garden
Correct answer: To provide step-by-step instructions for preparing a garden bed
The passage presents sequential actions (clear, test, amend, drain) that form a how-to process, making its primary purpose instructional.
When a passage presents actions in sequential order (first clear, then test, then amend, then create drainage), it's procedural or instructional writing. The primary purpose is to teach the reader how to do something. It doesn't argue for gardening (A), compare methods (C), or share personal experience (D). The practical, step-by-step structure clearly signals an instructional purpose.
Question 6: A passage discusses how different cultures celebrate the new year — fireworks in Sydney, temple bells in Japan, grape-eating in Spain, and water festivals in Thailand. What is the primary purpose?
- To argue that one country's celebration is best
- To show the diversity of New Year traditions across cultures (Correct answer)
- To provide a travel guide for New Year's Eve
- To explain the history of the Gregorian calendar
Correct answer: To show the diversity of New Year traditions across cultures
By presenting distinct celebrations from multiple countries without ranking them, the author's purpose is to illustrate the rich diversity of how cultures mark the new year.
The passage surveys four geographically and culturally diverse celebrations: Australia (fireworks), Japan (temple bells), Spain (grape-eating), Thailand (water festivals). No celebration is presented as superior, and no practical travel advice is given. The purpose is to inform readers about cultural diversity in New Year traditions. It's not argumentative (A), not a travel guide (C), and not about calendar history (D) — it's a comparative cultural survey.
A passage discusses how migratory birds navigate using the Earth's magnetic field, the position of stars, and landmarks.
