How an academic passage is built
- Academic passages are about science, history, nature or art. The first paragraph usually introduces the topic; each later paragraph has one main point.
- Questions come in a few types: main idea, detail, word meaning, reference, and why the writer mentions something.
Which question types appear with academic passages? Choose all that apply.

Questions ask about the passage, never about your opinion.
In an academic passage, each later paragraph usually has one main point.
難易度 1/5 · 100 コイン + 今日初回達成時の小ボーナス
The first paragraph introduces; each later one has one point.
Main idea and best title
- For a main idea 主旨 or best-title question, choose the option that covers the whole passage.
- An option about one paragraph or one example is too narrow. An option bigger than the passage (All about animals) is too wide.
A passage describes how honeybees find flowers, tell other bees where the flowers are, and store honey.
- Too narrow: How Bees Make Wax · Too wide: Insects of the World
- Best: How Honeybees Find, Share and Store Food
Too narrow, too wide or just right?

The first option is one detail; the third is too wide.
Details: find the line
- Detail questions use words like According to the passage…. Find the sentence and compare it with each option.
- The correct option usually says the same thing in different words; the wrong ones change a number, a cause or a result.

Reference words
- A reference word 指代词 (it, they, this, these, its, their) points back to something already named, usually the nearest noun that makes sense.
- Check by putting the noun in its place: "Owls hunt at night. Their large eyes collect light" → the owls' large eyes. ✓

Why does the writer say this?
- Some questions ask why the writer mentions something. Is it an example 例子, a comparison, a reason or a result?
- Signal words help: for example, such as (example); like, unlike, compared with (comparison); because (reason); so, as a result (result).
"Some trees share food through fungi under the ground. For example, an old tree can send sugar to young trees in its shade." Why mention the old tree? → To give an example of trees sharing food.

Common mistakes
- Choosing an option that is true but does not answer the question (a detail for a main-idea question).
- Taking the first noun in the sentence as the reference instead of the one that makes sense.
If an option states a true fact from the passage, it must be the answer to a main-idea question.
難易度 1/5 · 100 コイン + 今日初回達成時の小ボーナス
A true detail can still be the wrong answer if the question asks for the main idea.
A reference word always points to the first noun in the sentence.
難易度 1/5 · 100 コイン + 今日初回達成時の小ボーナス
It points to the noun that makes sense; test by replacing.
Recap
- Main idea: covers everything, not one part, not more than the passage.
- Detail: find the line, then match the meaning.
- Reference: put the noun back in. Purpose: example, comparison, reason or result.
