Selection
Learn how to identify the best summary of a passage by finding the answer that captures the main idea and key details without going too broad or too narrow.
What Is a Summary?
A summary is a short restatement of the most important information in a passage. It answers one big question: What is this passage mainly about?
On the ISEE, you will see questions like: "Which of the following best summarizes the passage?" Your job is to pick the answer choice that captures the whole passage accurately.

Anatomy of a Good Summary
The Summary Selection Rule
Summary vs. Main Idea vs. Theme
| Summary | Main Idea | Theme | |
|---|---|---|---|
| What is it? | A short retelling of the whole passage | The central point in one sentence | A universal lesson or message |
| Includes details? | Yes: key details | No: just the big point | No: abstract idea |
| Example | "The article explains how bees pollinate flowers and why this matters for food crops." | "Bees are essential pollinators." | "Nature's processes are interconnected." |
How to Find the Best Summary
The Elimination Funnel
Worked Example: Honeybees
Passage: Honeybees play a critical role in agriculture. As bees travel from flower to flower collecting nectar, they transfer pollen, which allows plants to produce fruit and seeds. Without pollination, many crops that people depend on, such as apples, almonds, and blueberries, would fail. In recent years, bee populations have declined due to pesticides and habitat loss. Scientists and farmers are now working together to protect bee colonies and promote pollinator-friendly farming practices.
Evaluating the Choices
Worked Example: Ancient Egypt
Passage: The ancient Egyptians built the pyramids as tombs for their pharaohs. The largest, the Great Pyramid of Giza, took over 20 years to construct and required thousands of workers. Egyptians believed that preserving the body through mummification would help the pharaoh reach the afterlife. They filled tombs with food, jewelry, and other goods the pharaoh might need. Today, the pyramids remain one of the most recognizable symbols of ancient civilization.
Testing the Choices
Advanced Example: Coral Reefs
Passage: Coral reefs, often called the "rainforests of the sea," support roughly one quarter of all marine species despite covering less than one percent of the ocean floor. Corals themselves are tiny animals called polyps that build calcium carbonate skeletons. Fish, sea turtles, and countless invertebrates depend on reefs for food and shelter. However, rising ocean temperatures cause coral bleaching, a process that weakens and can kill corals. Pollution and destructive fishing practices add further stress. Marine biologists warn that without urgent action, many reefs could disappear within decades.
Common Mistakes to Avoid
Summary Selection Cheat Sheet
| Trap Type | How to Spot It | What to Do |
|---|---|---|
| Too Broad | Could describe many different passages | Eliminate: lacks specific details from this passage |
| Too Narrow | Only covers one paragraph or fact | Eliminate: does not represent the whole passage |
| Inaccurate | Contradicts or distorts what the passage says | Eliminate: always check claims against the text |
| Outside Info | Adds facts not found in the passage | Eliminate: the answer must come from the text alone |

Question 1 of 5
The Amazon rainforest produces about 20 percent of the world's oxygen and is home to an extraordinary number of plant and animal species. Deforestation, primarily for cattle ranching and farming, has reduced the forest's area significantly. Environmental groups are working to slow deforestation through legal protections and community programs that offer alternatives to logging.

Question 2 of 5
In 1969, astronaut Neil Armstrong became the first person to walk on the Moon. The Apollo 11 mission was the result of nearly a decade of research, engineering, and test flights. Armstrong and fellow astronaut Buzz Aldrin spent about two hours on the lunar surface collecting samples and planting an American flag. The mission inspired millions of people and demonstrated the possibilities of space exploration.

Question 3 of 5
Octopuses are among the most intelligent invertebrates. They can solve puzzles, open jars, and even use tools. Their ability to change color and texture helps them camouflage themselves against predators. Researchers have observed octopuses escaping from aquarium tanks, suggesting a high level of problem-solving ability. Despite their intelligence, octopuses have short lifespans, typically living only one to two years.

Question 4 of 5
During the California Gold Rush of 1849, hundreds of thousands of people traveled to California hoping to find gold. While a few prospectors became wealthy, most found little or no gold and faced harsh living conditions. The massive migration transformed California's economy and population, leading to rapid growth of cities like San Francisco. The Gold Rush also had devastating effects on Native American communities, whose lands were seized and whose populations declined sharply.

Question 5 of 5
The invention of the printing press by Johannes Gutenberg around 1440 revolutionized the spread of information. Before the press, books were copied by hand, making them rare and expensive. Gutenberg's movable type allowed books to be produced quickly and cheaply. Literacy rates rose as books became more accessible. The printing press also helped fuel the Protestant Reformation, as pamphlets and translated Bibles spread new religious ideas across Europe.
