单选题
______ wings for the common man had to await the dawn of the space age to go back to the simplicity of their beginnings.
【正确答案】
C
【答案解析】[解析] 副词词义辨析。consequently“因此，从而”；regularly“定期地，有规律地”；ironically“讽刺地”；comprehensively“包括地，全面地”。根据句中had to await, go back to the simplicity of their beginnings判定，只有ironically符合句意。故答案为C。
