✅ 解答・解説（スコア目標付き）
Q1 → C. be submitted
💡 解説（目標スコア：900点）
“insist that + 主語 + 原形動詞（be動詞含む）” は 仮定法現在。
→ 指示・要求・提案を表す動詞の定番構文。
✏️ The manager insisted that the report be submitted by Friday.
Q2 → A. efficient
💡 解説（目標スコア：880点）
比較級を作る語が “much” → 形容詞を修飾。
“much + 比較級（more efficient）” が正しい。
“efficiently” は副詞で構文的に合わない。
Q3 → C. so that
💡 解説（目標スコア：860点）
「〜するために」＝ so that + 主語 + 助動詞構文。
→ so that their opinions will be considered が自然。
Q4 → A. to which
💡 解説（目標スコア：950点）
“respond to ～” の前置詞 “to” を残す → to which the audience responded。
関係詞＋前置詞構文は高難度ポイント。
Q5 → A. of
💡 解説（目標スコア：800点）
“make sense of ～” = ～を理解する。
熟語を知っているかどうかの純粋な語彙問題。
Q6 → C. have been
💡 解説（目標スコア：870点）
未来時制の従属節には現在形・現在完了形を使う。
“until all data have been reviewed” が正答。
Q7 → C. unless
💡 解説（目標スコア：820点）
“unless”＝「〜でない限り」。
支払いがなければ注文は処理できない → 否定条件の文脈。
Q8 → C. critical
💡 解説（目標スコア：890点）
名詞 “issues” を修飾する形容詞が必要。
“critical issues”＝「重大な問題」。
Q9 → D. therefore
💡 解説（目標スコア：880点）
文頭で「その結果」＝ therefore。
“consequently” も可能だが、リズム的に therefore が自然。
Q10 → B. which
💡 解説（目標スコア：900点）
“construction began last year” は補足説明 → 非制限用法の関係代名詞 “which”。
“whose” は所有、「where」は場所を指すため不適切。
