Paragraph revision: claim, evidence and reasoning

Original constructed exercise. The memo, response counts and paragraphs below are fictional teaching material, not published research, a student submission or a measured AI result.

Practice question: Should a campus library pilot later opening hours?

Practice memo — read before the paragraphs
P1 — In a fictional library feedback exercise during the week before exams, 24 current evening users chose to answer a short questionnaire. Eighteen said that they would use the library after its current closing time.

P2 — The questionnaire did not reach students who were absent from the library. It recorded stated interest, not visits after closing, study time or grades. Staffing costs were not assessed.

P3 — A librarian proposed a four-week trial of later hours, with hourly visitor counts and staffing records. The proposal had not been implemented when this memo was written.

Before revision
The library must permanently extend its opening hours because students learn better when it stays open later. The feedback memo proves this: eighteen respondents wanted to use it after closing. All students will therefore attend more often and achieve higher grades. There is no reason to spend time on a trial.

After revision
The feedback memo gives the library a reason to test later opening hours, while leaving the case for a permanent change unresolved. Eighteen of the 24 current evening users who answered the questionnaire said that they would use the library after closing (practice memo, P1). This indicates stated interest among these respondents, but it cannot establish attendance among all students or a benefit to grades: non-users were not surveyed and neither outcome was measured (P2). A limited trial could examine actual use alongside staffing requirements before a permanent decision, although the proposed trial has not yet produced those records (P3).

Decisions
Accept: narrow the claim — Permanent extension → a reason to test later hours — The memo describes interest and an unimplemented proposal, not the results of a trial (P1, P3).

Accept: restore context — Eighteen respondents → eighteen of 24 current evening users who answered — The denominator and recruitment context show whose interest was recorded (P1).

Accept: explain the inference — State what interest supports and what it leaves untested — Stated intention is different from a recorded visit; grades were not measured (P2).

Reject: remove the qualification — Delete “among these respondents” to make the statement sound decisive — The wording would conceal the limited group and overstate the reach of the evidence (P1–P2).

Reject: invent confirmation — Describe the proposed trial as successful — P3 says that the trial had not been implemented. A future check is not a completed result.
