Directions: Read the following passage and answer the question that follows:

THE BIRTH OF FAMILIES

Families formed as an answer to the questions faced by growing tribes in the early times. When the number of people of an early human tribe kept on growing, space became short. It became impossible to keep on sharing common roofs. The grazing, hunting and farming grounds close to the home of the tribe were no more enough to feed all. People had to cover greater distances in a day to get food. It became more and more difficult to carry back food from where it was found.

When people grew in skills and knowledge, it made life easier and plentiful. There was no more any need to share most of their belongings. So, people started to have personal belongings and attachments. This gave rise to greed and envy. Greater numbers of people meant greater differences between them. Everybody had his or her own tastes. So, it became harder to please everybody by common cooking.

To find an answer to these problems, the tribe divided into smaller groups called families that started to live and cook separately. Families built themselves around providers, or the persons who put food on the table, and were made up of blood relations of the main provider. Thus, the tribe grew from a family-less group to a group of families.
