Passage # 1:
A team of researchers has found that immunizing patients with bee venom rather than the crushed bodies of bees can better prevent serious and sometimes fatal sting reaction in more than one million Americans who are hypersensitive to bee stings. The crushed body treatment has been standard for fifty years, but a report released recently said that it was ineffective. The serum made from the crushed bodies of bees produced more adverse reactions than the injections of the venom did.
The research compared results of the crushed body treatment with results of immunotherapy, that used insect venom, and also with results of a placebo. After six to ten weeks of immunization, allergic reactions to stings occurred in seven of twelve patients treated with the placebo, seven of twelve treated with crushed body extract, and one of eighteen treated with the venom.

3. The number of patients who took part in the experiment descried was:
4. The most successful treatment described in the passage was a serum prepared from:
A. the blood of patients who had been stung.

Passage # 2:
The development of Jamestown in Virginia during the second half of the seventeenth century was closely related to the making and use of bricks. There are several practical reasons why bricks became important to the colony.
Although the forests could initially supply sufficient timber, the process of lumbering was extremely difficult, particularly because of the lack of roads. Later, when the timber on the peninsula had been depleted, wood had to be brought from some distance. Building stone was also in short supply. However, as clay was plentiful, it was inevitable that the colonists would turn to brick making.
6. What is the subject of this passage?
A. The reasons for brick making in Jamestown.
B. The cause of the failure of Jamestown
C. The laws of the early American colonies.
D. The problems of the early American colonies
7. In the first half of the 1600's most buildings in Jamestown were probably made of:
8. Which of the following was not a reason for using bricks in construction?
A. Wood had to be brought from some distance.
B. There was considerable clay available
C. The lumbering process depended on good roads.
D. The timber was not of good quality.
Passage # 3:
Prices determine how resources are to be used. They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is a very complex network composed of the prices of all the products bought and sold in the economy as well as those of a myriad of services, including labor, professional, transportation, and public-utility services. The interrelationships of all these prices make up the "system" of prices. The price of any particular product or service is linked to a broad, complicated system of prices in which everything seems to depend more or less upon everything else.
9. What is the best title for the passage?
A. The Inherent Weaknesses of the Price System
B. The Complexities of the Price System
C. Credit Terms in Transactions
D. Resource Allocation and the Public Sector
10. According to the passage, the price System is related primarily to:
A. labor and education
B. transportation and insurance
C. utilities and repairs
D. products and services
