A microprocessor-controlled car park barrier is used to allow cars to enter a car park. When a car approaches the barrier, the barrier automatically rises to allow the car to enter. It does not lower until the car is safely clear of the barrier system. There is a light sensor and light beam source immediately before the barrier. No tickets are issued by the system. The system operates continuously while it is switched on. Complete this pseudocode algorithm to describe the processing involved. Your pseudocode algorithm should include IF…THEN statements.

Insurance consultants have to make decisions about whether or not to accept a customer’s application for an insurance policy. They often use expert systems to help them assess the risk involved. Such a system would have a knowledge base, which consists of a database of facts and a rules base. Describe the other components of this expert system. Explain how this insurance expert system would be used by the consultant and how it would assess the risk.
