     I was telling my boy Sonny the story of the hare ( 兔子) and the tortoise ( 乌龟 ). At the end I said, " Son, remember: Be slow and steady ( 镇定的), and that will win the race. Don't you think there's

something to learn from the tortoise?"

     Sonny opened his eyes wide, " Do you mean next time when I'm entering for the 60-metre race I

should wish that Billy, Tony and Sandy would all fall asleep halfway?"

     I was shocked, "But the tortoise didn't wish that the hare would fall asleep!"

      "He must have wished that," Sonny said, "Otherwise how could he be so foolish as to race with the

hare? He knew very well the hare ran a hundred times faster than he himself did."

     "He didn't have such a wish," I insisted. "He won the race by perseverance ( 坚忍不拔的 ), by

pushing on steadily."

     Sonny thought a while. "That's a lie," he said. " He won it because he was lucky. If the hare hadn't

happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like,

or a hundred times steadier, but he'd never have won the race. That's for sure."

     I gave up. Today's children are not like what we used to be. They're just hopeless.

问答题

某水利工程施工监理招标项目。招标文件规定:①投标保证金金额为10万元人民币。招标人接受的投标保证金形式为:现金、银行汇票或银行保函;②投标函须加盖投标人印章,同时由法定代表人或其授权代表签字;③投标文件分为投标函、商务文件、技术文件三部分,均须单独密封,否则招标人不予接收。
投标人共有6家,分别为A、B、C、D、E和F。投标文件的递交情况如下:
投标人A提前一天递交投标文件,其投标函、商务和技术文件被密封在同一个文件箱内,投标保证金为10万元人民币的银行保函。
投标人B在投标截止时间前递交投标文件,其投标函、商务文件、技术文件单独密封,但其投标保证金10万元人民币现金在投标截止时间后10min送达招标人。
投标人C在开标当天投标截止时间前按时递交投标文件。投标函、商务和技术文件单独密封,其投标保证金为5万元人民币的银行汇票。
投标人D的投标文件于投标截止时间前1天寄达招标人,但其参加开标会议的代表迟到10min抵达开标现场。
投标人E、F的投标文件均提前递交,并符合招标文件要求。
招标人接收了投标人A、B、E和F递交的4份投标文件。因投标人C的投标保证金金额不足、投标人D的投标人代表迟到,招标人拒绝接收其投标文件。
唱标过程中,投标人A的投标函上没有其法定代表人或其授权代理人签字,招标人唱标后,当场宣布A的投标为废标;投标人B的投标函上有两个大写投标报价,招标人要求其确认了其中一个报价后进行唱标;投标人E的投标报价,大写为壹佰捌拾捌万元人民币整,小写为180万元人民币,招标人按照有利于招标人的原则按180万元人民币唱标。
唱标结束后,招标人要求每个投标人在开标会记录上签字。投标人F认为招标人组织的开标存在问题,拒绝在开标会记录上签字,招标人当场宣布其投标为废标。
这样仅剩B、E两个有效投标人,评标委员会经评审后认为有效投标少于3家,明显缺乏竞争性,于是否决了所有投标。
[问题]

在本项目中,评标委员会是否有权否决所有投标招标人下一步应采取什么措施
