5. As its sales of computer products have surpassed those of measuring instruments, the company has become increasingly willing to compete for the mass market sales it would in the past have conceded to rivals.
(畫線部分已經為正確答案)

有牛人知道為何it would in the past have conceded to rivals要用助動詞加完成式嗎?
用助動詞加完成式不是代表與過去事實相反嗎?
這裡的句意,應該不是假設語氣吧,應該是陳述過去已經發生的事實吧?

還是說把would與have conceded分開看,have conceded代表從過去一直到現在退讓的情況,而would為單獨語氣客氣的用法?

有哪位賢拜可以幫忙嗎?

在過去讓出原本不應該讓出的的市場.
假設語氣表示應做而未做.
