[单项选择]It might be supposed that greater efficiency could be achieved if several people worked together to solve a problem than if only one individual works on it.
Although groups often may increase the motivation of their members to deal with problems, there are conflicts arising among members of a group. Problem solving needs the presence of an effective leader who not only provides direction, but also permits the orderly, constructive expression of different opinions; much of the leader’s effort may be devoted to resolving differences. Success in problem solving also depends on the distribution of ability within a group.
Although groups may reach a greater number of correct solutions, or may require less time to discover an answer, their efficiency is typically lower than that achieved by skilled individuals working alone.
In brainstorming, a problem is presented to a group of people who then proceed to offer whatever they can think of. Theoretically these unrestricted sugge
A. the presence of an effective leader
