Bài 9: Đọc đoạn văn dưới đây và chọn phương án trả lời đúng. Communication in Groups The sheer number of people in a group affects the amount of communication. Consider the difference between communication between two friends and communication in a group of five people. When friends talk, there are two people sending and receiving messages. In a group of five, there are five people doing the same thing. Each idea that is expressed must be understood by four others, who may also choose to respond. Consequently, the greater number of people in a group, the fewer contributions any individual may make. Because there are disadvantages to large groups, you might assume that small groups would be the most effective. However, groups can’t be too small as well as too large. With too few members, a group has limited resources, which eliminates a primary advantage of group for decision making. Also, in very small groups, members may be unwilling to disagree or critisize each other’s ideas. I believe that five to seven members is the ideal size for a small group. 1.
