Practice identifying the true central main idea of an expository paragraph. Differentiate the complete main idea from titles that are either too narrow (just a single detail) or too broad.
Directions: Read each paragraph carefully. Choose the letter of the title that expresses the complete main idea.
Paragraph 1: Archaeology & Ancient Dwellers
Findings in caves have given us many clues as to how ancient people lived. As people have dug through layers and layers of dust, they have found such things as cooking pots, stone axes, weapons, and stone needles which were used by cave dwellers thousands of years ago. In 1927 someone found a tooth which came from an ape-like person. Because it was near Peking, China, the person was called the Peking man. We know that the Peking man knew how to use tools and fire because tools and fire-places were discovered nearby.

Paragraph 2: Pioneer Sod Houses
Some of the earliest houses on the plains were built of sod. There were few trees, and wood was scarce. As farmers began breaking up the ground for planting crops, they got an idea. The thick sod was tightly woven with the roots of grass. Why not use sod "bricks" for the walls of their homes? Soon sod homes became a common sight on the broad plains. Not only were they warm in winter, but they were cool in summer.

Paragraph 3: Native American Shield Designs
Indians of long ago painted designs on their shields for a good reason. They believed that the designs had a magical power in battle. In their dreams they were shown what kinds of designs to paint. The designs would offer protection. The shield was made from the tough skin of a bull buffalo and protected them from arrows but not rifle fire. Even so, the Indians still had great faith in the power of the designs.
