问题：which can be inferred from paragraph 2?
原文：
◆ People are bound within relationships by two types of bonds: expressive ties and instrumental ties. Expressive ties are social links formed when we emotionally invest ourselves in and commit ourselves to other people. Through association with people who are meaningful to us, we achieve a sense of security, love, acceptance, companionship, and personal worth. Instrumental ties are social links formed when we cooperate with other people to achieve some goal. Occasionally, this may mean working with instead of against competitors. More often, we simply cooperate with others to reach some end without endowing the relationship with any larger significance.
答案：1)Instrumental ties can develop even in situations in which people would normally not cooperate.
        2)Instrumental ties require as much emotional investments as expressive ties.
        3)Instrumental ties involve security, love and acceptance
        4)Instrumental ties should be expected to be significant

我选的是4），可答案是1），一直不明白为什么，求解答，谢谢

4是没法被列为正确答案的，你看这段的最后一句More often, we simply cooperate with others to reach some end without endowing the relationship with any larger significance.

而1的这句话Instrumental ties can develop even in situations in which people would normally not cooperate. 是讲instrumental ties可以从什么情形演变过来。所以完全可以是从不合作的人们间演变成这种关系啊。所以正确。
