Answer:
Because with help from groups, we may be able to attain goals we may not achieve individually.
Step-by-step explanation:
In groups we collaborate with each other, empathize with one another and share values. It is nearly impossible for any individual work to make remarkable impacts or success without the support of others. These individuals aid the attainment of goals we may not be able to attain based on our solitary efforts. In groups we have our most social interaction and complementary skills are been used to achieve the set out goals.
