Eメール｜公開研究会の申込と受付

From: City Research Forum Subject: Registration details All school teams must upload a written outline by Tuesday, November 24. The system will send a receipt within one hour of receiving a complete file, but this receipt does not confirm technical approval. Selected teams should reply within two days of receiving a separate confirmation message. The event will begin at 10 a.m. on Saturday. Registration remains open until 9:30 a.m., and teams should complete check-in by that time. During the opening talk, electrical models must stay switched off. Devices may be used only after trained staff have completed safety inspections. Please keep the original presentation file available until the technical review is finished.

問37｜What must teams finish by 9:30 a.m.?

問38｜Does a receipt sent within one hour establish safety approval?

説明文｜図書館の夜間運営

A public library tested later opening hours during the school examination season. It asked people to submit feedback by the end of each week. The main reading room remained open until nine o’clock on two weekdays, but the equipment desk closed at six. During the trial, staff recorded the number of visitors and the cost of extra supervision. Some families found the new timetable convenient, while others could not use the library because buses stopped running early. Managers said that attendance during a busy examination month might not represent demand throughout the year. They planned to review the results within thirty days of the trial ending. The council would not decide whether to make the change permanent until the report was complete.

問39｜When did the equipment desk close?

問40｜When would the council consider a permanent change?

説明文｜学校の機器保守規則

A school has introduced new rules for lending digital readers. Pupils must complete safety training by the first day they borrow equipment. If a reader stops working, they must report the problem within 24 hours of discovering it. The staff do not allow pupils to repair electronic wiring themselves. During the maintenance period, damaged devices are kept in a locked room. They remain unavailable until trained technicians have examined them. The library sends a message after inspection, explaining whether repairs or replacements are possible. A borrower who reports damage within the required time is not automatically entitled to a free replacement; the lending policy and circumstances still apply.

問41｜How soon should damage be reported?

問42｜When can a damaged reader become available again?

説明文｜町の橋の安全確認

A historic bridge was closed after engineers found loose supports. The town announced that repairs should be completed by the end of the month, but the bridge would remain closed until a final inspection confirmed it was safe. Residents were directed to an alternative route during construction. Inspectors planned to evaluate the bridge within a week of the repair work being finished. The alternative route was longer but had ramps and resting places. During the closing period, the town also collected feedback from residents who used wheelchairs or strollers. Officials explained that a construction deadline was not the same as a confirmed reopening date. Safety approval was required before the public could cross the bridge again.

問43｜Does completion of repairs by month-end guarantee reopening that day?

問44｜When will inspectors evaluate the bridge?
