[問題] 考古題0410 Q37 (structure)

[evolutiongene]

Among the most complex crystals are that of silicon dioxide, which has seven different structures at
various temperatures and pressures, the most common being quartz.

是選錯題, 答案就是B (劃線的地方)
可是不太明白 為什麼錯?
要如何改才能成為正確的句子?

[dvorak]

that -> those
原句主詞："Those of silicon dioxide"
倒裝句還原：Those of silicon dioxide (which are among the most complex
crystals) are, which has seven....pressures, the most common being quartz.
