説明文A｜電子教材と紙の代替案

A secondary school introduced online worksheets to help students practise English at home. Many pupils enjoyed the exercises, but some families did not have reliable internet connections. The school therefore offered printed materials as an alternative to digital lessons. Teachers checked that the two formats provided equivalent learning goals, although they did not have exactly the same appearance or functions. When a student’s tablet failed, a replacement device could be borrowed after inspection. The librarian explained that borrowing a replacement was separate from receiving a refund for a privately purchased device. Managers collected feedback before deciding which resources to expand.

問37｜Why were printed worksheets introduced?

問38｜What did the school try to make equivalent?

説明文B｜地域の科学展示

A science center planned an exhibition featuring a model electric motor. The device failed its inspection shortly before the event. A specialist said that repairing it would take several days. The organizers used a wooden substitute to explain the motor’s basic shape while displaying photographs of the working mechanism. They did not claim that the substitute performed functions equivalent to those of the electrical motor. The center also arranged a replacement part for a later demonstration. Visitors were told that the hands-on electrical activity was unavailable until a trained technician had completed the safety review.

問39｜What was used during the exhibition instead of the motor?

問40｜Did the wooden model have equivalent functions to the motor?

説明文C｜通院のための交通手段

A town compared two public transport routes to its hospital. One route was shorter but included a steep path to the final stop. The other took longer but had a step-free entrance and places to rest. Staff said the routes were not equivalent in accessibility, even if the average travel times were sometimes similar. The council considered a shared taxi as an alternative for residents who could not use either bus route. During the trial, a substitute driver was needed on one day, but the timetable remained unchanged. The town recorded passenger numbers and operating costs before adopting a permanent policy.

問41｜Why were the bus routes not equivalent in accessibility?

問42｜What alternative was considered for some residents?

説明文D｜地域の貸出工具

A community center lends simple household tools to residents. If a device is returned with damage, trained staff inspect it and determine whether repair or replacement is appropriate. Several borrowers believed that receiving a substitute tool meant that the center had approved a refund for the original item. Staff explained that an exchange, a temporary substitute, and a refund were separate arrangements. Replacement tools should be equivalent in their intended safe functions, but the center could not guarantee that different models would have identical features. The managers revised the borrowing policy to make these differences clearer and reminded users to request approval before doing repairs themselves.

問43｜What misunderstanding did some borrowers have?

問44｜What did the center say about replacement tools?
