✅ 解答・詳細解説（＋目標スコア）
Q1. 正解：A. implement

「a high level of 〜」の後は名詞を置く。「customer satisfaction（顧客満足）」が自然な名詞句。
Q3. 正解：C. manufactured
🎯 目標スコア：850点以上
「are + 過去分詞」で受け身。「製造される」＝ are manufactured。文構造を見抜く練習。
Q4. 正解：D. would have developed
🎯 目標スコア：900点以上
「Had＋過去分詞」＝仮定法過去完了 → 結果節に「would have＋過去分詞」。

「〜のおかげで」＝ owing to / due to / thanks to。文法的に完全文に続くのは「owing to」。
Q9. 正解：A. consistent
🎯 目標スコア：800点以上
「be consistent with 〜」＝「〜と一致している」。TOEIC頻出のコロケーション。
Q10. 正解：C. access
🎯 目標スコア：750点以上
「prevent A from B-ing」構文だが、ここでは「unauthorized access（不正アクセス）」が名詞として自然。
💬 総評
今回のセットは 仮定法・関係代名詞・名詞構文・前置詞句 などTOEIC文法の核心をカバーしています。
900点以上を目指すなら、文構造の理解＋語法の正確さ がポイントです。
特に「demand that〜」「owing to〜」「consistent with〜」のような定型表現は暗記必須です。
