Main Idea and Summarizing — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Honeybees do a waggle dance to tell other bees where flowers are. The dance shows direction and distance. What is the main idea?
A) Bees like to dance.
B) Flowers grow in many places.
C) Honeybees communicate the location of food through dance.
D) Bees travel long distances every day.
Both details describe how bees use the waggle dance to share information — the main idea ties them together.
2. A student writes this summary: "The article was about stuff that happened a long time ago." What is wrong with this summary?
A) It is too specific.
B) It is too vague and does not name the topic or key details.
C) It includes too many facts.
D) It copies directly from the article.
A good summary names the specific topic and key points — "stuff that happened" is meaninglessly vague.
3. A passage states that ancient Egyptians built pyramids as tombs for pharaohs, used thousands of workers, and moved huge stone blocks. Which is the best main idea?
A) Pyramids are made of stone.
B) Ancient Egyptians built massive pyramids to honor their rulers.
C) Workers carried heavy things.
D) Egypt is in Africa.
Both details — tombs for pharaohs and massive stones — support the main idea of monumental construction for rulers.
4. Which strategy helps you find the main idea of a long passage?
A) Read only the last paragraph.
B) Look at the pictures and guess.
C) Read headings and the first sentence of each paragraph.
D) Count the number of paragraphs.
Headings and topic sentences are the most reliable location markers for main ideas in longer texts.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A main idea that is not stated directly is called an implied main idea.
An implied main idea is not explicitly stated — the reader must infer it from the supporting details.
2. Summarizing requires you to restate the most important information in fewer words.
Restating key information in fewer words is the core skill of summarizing — capturing meaning concisely.
3. Key supporting details provide evidence, examples, or reasons for the main idea.
Supporting details take the form of evidence, examples, and reasons that back up the main idea.
4. When the main idea is not in one sentence, you must infer it from all the details.
An implied main idea requires inference — the reader combines all details to determine the central point.
5. A summary should never include your personal opinions about the topic.
Summaries are objective restatements of the author's ideas — the reader's opinions do not belong in a summary.
