有關TPO8 lecture 2 第10題 排序時間的題目
為什麼 Inexpensive eyeglasses became available 是排在第二個呢?
不是越多人有閱讀的需求,才有inexpensive eyeglasses 出現嗎?

部分原文:
Suddenly, book became widely available and more prople wanted to read.

So, the need, oh well, actually not only the need but the demand for

more affordable glasses rose drastically. Eventually, inexpensive glasses

were produced, and then glasses were available to everyone.

教授不是講說最後 inexpensive glasses were produced 嗎?
那為什麼是排在第二個呢?
