Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

As societies developed they set up schools to teach reading, writing, maths and other subjects.

          The first schools were usually just for boys. Most of the students came from rich and powerful families. Often the purpose of their education was religious training. In many cultures the religious leaders formed the highest level of society. Some schools had other purposes as well. Many schools focused on military training. Sometimes youths attended special schools to learn the art of public speaking. These skills were meant to help them become future leaders.
