Natural speed please.
In the lecture, the lecturer refutes the idea that teamwork is the best way to get projects in most fields done, which is supported in the reading passage.
First, the reading states that teams get work done more quickly. The two reasons given are that there are many people to share the tasks and that each team member can contribute his or her individual strengths. However, the lecturer points out that teams take longer to get tasks accomplished. They have to spend time building consensus among members before making decisions about what should be done, and people often argue a lot even over small parts of the project. Therefore, the statement that teams get work done more quickly is not acceptable.
Second, the reading insists that teamwork produces more creative solutions to problems, because the team members can brainstorm for ideas that involve everyone's strengths and opinions. In contrast, the lecturer argues that it doesn't work that way in reality. Instead, one or two bossy people tend to push everyone else into keeping their ideas to themselves and just following along. Therefore, the insistence that teamwork produces more creative solutions to problems is not receptive.
Third, the reading maintains that people on project teams work hard. This is because the work can be shared in smaller, easier pieces and because they know that everyone will be recognized if the project goes well. On the contrary, the lecturer claims that team projects make it easier for lazy people to avoid work. The two reasons are that there is always someone else on the team to pick up work one person doesn't do, and every member ultimately shares credit or blame for the project no matter what the individual contribution. Therefore, the claim that people on project teams work hard is not understandable.
In conclusion, from the three points, the idea that teamwork is the best way to get projects in most fields done is refuted by the lecturer.
