看答案
upgrades
逐一代入後，two software upgrades 是唯一正確的名詞片語：two 要求複數可數名詞。upgrade 是單數；upgraded 是動詞過去式／過去分詞，不能充當此處所需的複數名詞；upgrading 雖可作表示活動的名詞，但此形式不能直接接在 two software 後表示兩項升級。
同義改寫
The new equipment represents a significant upgrade in scanning speed. → The new equipment represents a significant improvement in scanning speed.
此處 upgrade 指掃描速度的提升，以 improvement 替換後仍表示同一項效能改善。
Ms. Lin asked about an upgrade from economy to business class for her work trip. → Ms. Lin asked about moving from economy to business class for her work trip.
兩句都表示詢問出差航程從經濟艙升至商務艙的可能性，未表示升等已獲確認或免費。
