Take it into a passage
A quieter study space
The library committee proposed turning an unused room into a quiet study space. Its claim was simple: students needed somewhere to work without interruption. At first, the evidence consisted of comments from three friends. Maya questioned whether that small group gave a complete perspective. The committee then asked students from several grades and recorded their responses. The larger survey made its case more credible, although not everyone agreed. Some students were reluctant to lose the room as a meeting space. To resolve the disagreement, the committee proposed quiet study on three afternoons and club meetings on two. Its final presentation was coherent: it explained the need, showed the survey results, and addressed the different uses of the room.
Explain your thinking
Why did the committee collect more responses before making its final proposal?
See a sample response
Three friends represented only a small group. Asking students from several grades gave the committee a broader perspective and stronger evidence for its claim. The survey still did not mean everyone agreed.
Write with the words
Write 4–6 sentences proposing one improvement at your school. Use claim, evidence, and relevant accurately. Explain what information you would collect before deciding whether the change is useful.
See the words in a story
Watch a short story, check your understanding, and explain the word in a new situation. These companion videos and exercises are free to use without an account.
