完成させるための元の文は次のとおりです。 "He asked me _____ Robert and I said I did not know _____."

1. **選択肢a: that did I know / who were he **

- "that did I know" : この構造は標準的な英語の文法では正しくありません。報告された文節の開始に「 that 」を使用する場合、動詞は疑問文ではなく肯定文の順序になければなりません。
- "who were he" : 語順が間違っています。正解は"who he was"でしょう。

2. **選択肢b: that I knew / who he had been **

- "that I knew" : 比較的大丈夫ですが、質問の文脈では完全には意味がありません。
- "who he had been" : 語順は正しいですが、 "had been"質問されている現在の文脈に適合しません。

3. **選択肢c: if I knew/ who he was **

- "if I knew" : 正しい文法構造と意味。ここでの「 If 」は、話者の知識についての確認や不確実性を表現するために使用されます。
- "who he was" : 報告された文の文法的に正しい構造。タイトル文が"did not know".

4. **選択肢d: whether I knew / who had he been **

- "whether I knew 」: この構造は文法的に正しく適切ですが、この文脈では「 if 」よりも一般的ではありません。
- "who had he been 」: 語順が間違っています。正解は"who he had been"です。

したがって、上記の分析から、最も正確な選択は次のとおりであることがわかります。

**c. if I knew / who he was**

全文を大まかに翻訳すると、 "He asked me if I knew Robert and I said I did not know who he was." （彼は私にロバートを知っているか尋ねました、そして私は彼が誰であるか知らないと言いました。）
