 * The new music**

Suggested answer:

In the period 1966-7, three separate kinds of music - folk, rock and blues - were brought together, and influences from other traditions, for example, Indian, were added, to make a much more complex sort of music expressing new attitudes. Electronic devices were used to give music a new sound: it became much louder, and was associated with lighting effects. This, and the use of drugs, made the audience feel that they were not just listening passively, but participating in a 'total experience'.


 * Lie detector**

Suggested answer:

According to the manufacturers, the machine can help both police and private industry to investigate people's honesty. Firms can use it to test applicants for jobs; for instance, to check on drug use or political attitudes, and to see whether their staff are honest. Insurance investigators could use it to detect false claims, and to see whether clients will accept less money than they should get. There are three main objections: the machine only detects stress, which may not be due to dishonesty; it could be used for political control; and its accuracy depends on the skill of the operator.


 * The causes of conflict**

Suggested answer:

The author found three main causes of fighting among apes and children. The first was the desire for possession: the resulting fighting could lead to the destruction of the toy or animal desired. Among children, a possession might be valued, and fought for, only when another child wanted it. Jealousy is a form of possessiveness. A second cause was aggression against a strange child or animal, but not against a member of another species. And finally, frustration can lead to aggression against a totally innocent object or person; the author sees this as an important cause of conflict.
