3. According to the reading, the university is planning to give a free tennis class to students.
The woman thinks it is a good idea.
First, she says that more students will be able to take advantage of free tennis classes. To be specific, the previous tennis class is costly for students who have tight budget. So there have been a lot of students who give up taking the course. Now with free classes, students can learn how to play tennis.
Second, she mentions that students can meet more people who are interested in the tennis. With the free class, more and more people will attend the tennis class. This means that it will be easy to find a partner to play with.
For these reasons, she believes that providing a tennis class for free is a good idea.
4. According to the reading, an information overload is that people tend to overlook important things when they are bombarded with too many information.
The professor explains this concept by giving two examples.
First, she describes that today's employees receive a large number of emails each day. They do not have enough time to each and every email so they read only emails that seem urgent than others. This has risks that employees may miss out on important information.
Second, she describes how pervasive the internet ads are. People's brain can not deal with too many ads so they ignore all the ads completely. For example, one poll showed that 82% of the internet users do not pay attention to the internet ads. This means that the internet ads are not effective.
These examples illustrate the information overload.
5. The woman's problem is that she wants to throw a party at her home but water supply will be shut off in her home at the party day.
The man suggests two possible solutions to the problem. One suggestion is to hold the party somewhere else. Second suggestion is to use a bottled water.
I think that second suggestion is better for her. This is because it's almost impossible to find a place to accommodate large groups. People usually do not want to host many people into their house. Also even if she has to cut down on budget for decoration and food, she can still organize the party when she buy enough bottled water.
For these reasons, I would recommend the second option for her.
6. The professor explains group influence by giving two examples.
First, he describes informational influence. When people are in obscure situation, they tend to rely on dominant group's view. One study illustrated this tendency. In experiment setting, researchers asked subjects to identify a man who was shown to them for very short time, After fake subjects that were larger than genuine subjects selected wrong man, real subjects always conformed to dominant opinion.
Second, he describes normative influence. This occurs when people adjust their superficial aspects to the group's norm. For example, teenagers are inclined to change their interests and hobbies out of the blue. This is because they follow what friends do to meet group's expectation.
These two examples show the group influence.
