這篇托福閱讀文章出自托福TPO考古題 Reading-Official 10 passage 1 Chinese Pottery
考古題網站(https://reurl.cc/lexmyd),捲動至網頁Official 10 Passage 1,鼠標移至上方會浮現在線做題,點選即可觀看文章

其中在第十一題:
選項B是對應到第五段的最後一句: Only when European decorative themes were introduced did these meanings become obscured or even lost.
但是選項B我有疑惑
Their significance may have remained clear had the Chinese not come under foreign influence.
這是假設語氣的倒裝(If the chinese had not come under foreign influence, their significance may have remained clear)(與過去事實相反-if條件句用過去完成式,結果句用情態助動詞would….have+past participle)
我的疑問是結果句的情態助動詞為什麼是用現在式may而不是過去式might?
我在一個網站上看到以下說法:https://reurl.cc/5pAjXq
但我也有看到另一種說法:https://reurl.cc/RXZ58x
所以在這個選項的選項的句子用may,可以解釋成發生的機率比用might大?
接著在第五段的開頭有一句:
Just as painted designs on Greek pots may seem today to be purely decorative, whereas in fact they were carefully and precisely worked out so that at the time, their meaning was clear, so it is with Chinese pots.
其中
whereas in fact they were carefully and precisely worked out so that at the time, their meaning was clear
是插入句嗎?
但是whereas是轉折連接詞,我有點不太確定? 謝謝。
