B. Because people want to make them hard.

C. Because people want to keep them forever.

题目解答

答案

A. Because people want to leave their names in the copies.

解析

本题考查对“hard copies”（硬拷贝）保留原因的理解。关键在于理解题干中“important documents”的核心需求，即签名（sign their names）这一实际应用场景。选项A直接对应这一需求，而其他选项存在对“hard”词义的误解或未提及关键功能。

  1. 理解题干核心：
    题干指出，尽管电子文件管理高效，但重要文件仍需保留硬拷贝。关键点在于签名这一物理操作需要纸质形式完成。

  2. 分析选项：

    • 选项A：正确。硬拷贝便于通过手写签名确认文件有效性，符合“leave their names”（留名）的实际用途。
    • 选项B：错误。“hard”在此指物理形式（纸质），而非“使文件变硬”。
    • 选项C：错误。永久保存可通过电子备份实现，硬拷贝并非唯一或最佳选择。
