问题 At the very beginning, Sam Walton believed that he would earn much money even if he sold products at lower prices than his opponents.
In order to gather much more data, Wal-Mart preferred ______ to bar codes.
选项
答案RFID tags
解析 第2个小标题Wal-Mart Strategy部分的第2段最后一句：RFID tags hold significantly more data than bar codes．空白处需要名词性成分。根据原文，RFID tags包含了比bar code更多的数据题目前半部分说为了掌握更多数据，那么Wal-Mart肯定更偏爱RFID tags，而非bar code了，故答案为RFID tags。
