A Second Life for Clothes
Every year, millions of tons of clothes are thrown away around the world. Most of them end up in landfills, even though many are still in good condition. To reduce this waste, some clothing companies have started collection programs. Customers bring old clothes to stores, and in return they receive a discount on their next purchase. The collected items are sold again as used clothing or turned into new materials. Supporters say these programs help people think more carefully about what they buy.

正解は③。第4文 in return they receive a discount on their next purchase（次回の購入の割引）を「後で買う物が安くなる」と言い換えている。
(7)According to the passage, what do supporters say about the programs?
正解は④。最終文 help people think more carefully about what they buy（買う物についてより慎重に考える助けになる）の言い換え。
