[問題]想請問一個作文的題目…

[阿琪]

想請問一個作文題目，內容為：
what discovery in the last 100 years has been most beneficial for people in your country? Use specific reasons and details to support your choice.
想了許久，還是想不到有什麼重要的發現耶(而且還要對人類有益的)…關於這題，不曉得各位大大有沒有任何想法或策略可以分享一下滴…

"gold" would be an interesting answer. since most of countries have the same discoveries, however, it's quite special that it was the only metal found in lots quantities in taiwan.............

這要怎麼寫啊? 還是不了解...台灣有什麼發明可以寫這個題目呢
