How to Answer Text Structure and Purpose Questions
Some of these questions are like the central idea questions where the answer is related to the ‘central’ or ‘main idea’. But not always. Sometimes the answer is about why the author is saying what they are saying in the text, or, what a piece of text that is underlined means in the context of the text.
TEXT STRUCTURE AND PURPOSE QUESTION 1
The following text is from Holly Goldberg Sloan’s 2017 novel Short.
More than two years ago my parents bought a piano from some people who were moving to Utah. Mom and Dad gave it to my brothers and me for Christmas. I had to act really happy because it was such a big present, but I pretty much hated the thing from the second it was carried into the hallway upstairs, which is right next to my bedroom. The piano glared at me. It was like a songbird in a cage. It wanted to be set free.

TEXT STRUCTURE AND PURPOSE QUESTION 4
Q4. In many agricultural environments, the banks of streams are kept forested to protect water quality, but it’s been unclear what effects these forests may have on stream biodiversity. To investigate the issue, biologist Xingli Giam and colleagues studied an Indonesian oil palm plantation, comparing the species richness of forested streams with that of nonforested streams. Giam and colleagues found that species richness was significantly higher in forested streams, a finding the researchers attribute to the role leaf litter plays in sheltering fish from predators and providing food resources.
Which choice best states the main purpose of the text?
Choose 1 answer:
- A It explains the differences between stream-protection strategies used in oil palm plantations and stream-protection strategies used in other kinds of agricultural environments.
- B It presents a study that addresses an unresolved question about the presence of forests along streams in agricultural environments.
- C It discusses research intended to settle a debate about how agricultural yields can be increased without negative effects on water quality.
- D It describes findings that challenge a previously held view about how fish that inhabit streams in agricultural environments attempt to avoid predators
HOW TO ANSWER TEXT STRUCTURE AND PURPOSE QUESTION 4
- The text describes how streams have better resources for life if in a forest.
- It is not about oil palm or water quality, so not A or C
- Does it answer an ‘unresolved question’ – the text does say ‘but it’s been unclear’ and ‘To investigate the issue’ so B is a candidate
- It mentions ‘sheltering fish from predators’ but this is not the main purpose of the text, so the answer is B
TEXT STRUCTURE AND PURPOSE QUESTION 5
Q5. Porcelain originated in China around 2,000 years ago, but its production remained a mystery to the Western world for centuries. During the Ming Dynasty (1368-1644 AD), the Chinese began exporting porcelain objects to Europe. Captivated by the delicate beauty, translucence, and strength of the “white gold,” the Europeans became obsessed with discovering the secret to its creation. It wasn’t until the early 18th century that the alchemist Johann Friedrich Böttger unlocked the secret, producing the first hard-paste porcelain manufactured outside of China in his factory in Meissen, Germany.
Which choice best describes the function of the underlined sentence in the text as a whole?
Choose 1 answer:
- A It describes the person responsible for introducing porcelain to Europe.
- B It emphasizes the longstanding European desire to create porcelain themselves.
- C It identifies when and where porcelain eventually began to be produced in Europe.
- D It suggests that Europeans eventually innovated on the older Chinese techniques of porcelain production.

- It does talk about a person but it does not ‘describe’ him, and did he introduce porcelain? so not A
- B is true, but the underlined text really talks about the who and when rather than the desire, not B.
- C is a clear match for the text, so really likely it is C
