Answer:
- to gather opinions
- to brainstorm new ideas
- to get ready for tests
- to come to a decision
Step-by-step explanation:
Group thinking can't be used to make faster decisions because a group has to go through the opinion of each member of the group and the debate about why they think that. But it does help to decide something in the general sense. It also helps to gather opinions because there is more than one opinion in the mix, which is also a good way to brainstorm and learn new things.
