Directions: There are five reading passages in this part. Each passage is followed by five
ques- tions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.

Passage One

Walking through the dry leaves on his way home, Pat thought of what a bad day in school it had been. But every day was a bad day for him; he and the school did not like each other. But now that he was in the forest, Pat began to feel more like his usual self. He stopped to look at the quick moving stream of water called the Totopotomy. This little river was named for a man Pat liked, Totopotomy chief of the friendly Paumunkey Indians. He had heard stories about boys caught by the Paumunkeys who, when they were free, did not want to go home. Pat could understand how they felt. They did not have to go to school; they lived in the fresh air, and went fishing and hunting. How wonderful that must be!

The gentle sounds of a bird singing could be heard through the trees. Pat looked up, and tried to make the same sound. Uncle Langloo had told him to try and learn the language of the birds, and he was trying. Pat wanted to be like his uncle in every way. Langloo Win- ston was a hunter who spent most of his time living with the Indians. He fished with them, talked with them, even dressed like them, and the Indians loved him.

When Pat reached home, a young slave named Caesar ran out to meet him. Pat gave him a friendly push, and both boys rolled in the red earth. Caesar's job was to serve Pat, but he was more friend than servant. Even as a boy, Pat Henry did not believe in such differences between men.

36. The Paumunkeys did all the following except ______.

A. not having to go to school

B. living in the fresh air

C. going fishing and hunting

D. not wanting to go home
