Questions 1-2 are about the following passage.

    Studies about social groups are a very interesting aspect of psychology because they show how differently people act when they are influenced by the thoughts and emotions of others. Studies have found that different people respond differently to group situations. When placed in a group, some people tend to dominate; they are natural leaders. However, the majority of people take a passive role.

    When in a group, most people rarely work as hard as they do alone. This phenomenon is known as "social loafing." There are several explanations for why it occurs, but mainly it's because the responsibility and the reward are divided in more ways. People are more willing to let others do the work for them and rely on other people. When people are alone, they have to take care of themselves. This gives them incentive to work harder.

    Also, when people are in groups they tend to adopt the opinions of the people that they are with. Time and again studies have shown that people forget themselves and act on the will of the group rather than sticking to their own principles. This is called the "conformity pressure," and very few people can honestly say that they do not fall prey to this. If someone is in a group of people who love the theatre, they will not tell them how much they hate it for fear of being left out of the group.
