Read the following passage. Choose and circle the correct answer A, B, C or D. According to the World Health Organization (WHO) research, the emission from car exhausts causes more deaths than road accidents. The research found that one third of all harmful air pollution was caused by road transport, and that long term exposure to pollution caused estimated 21,000 premature deaths a year across the three countries, France, Austria and Switzerland. This is much higher than the 9,947 who died that year as a result of road accidents. In addition, the researchers calculated that the car fumes caused 300,000 extra cases of bronchitis in children, and 15,000 extra hospital admissions for heart disease made worse by the pollution. They calculated that the cost of dealing with all this was 27 billion Euros per year. A lot of money goes into making cars safer, but not as much is spent solving air pollution. 1.

The toll of road accident 2.According to the passage,.......................................................... A. air pollution causes more deaths than road accidents.

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

In the history of technology, computers and calculators were innovative developments. They are essentially different from all other machines because they have a memory. This memory stores instructions and information. In a calculator, the instructions are the various functions of arithmetic, which are permanently remembered by the machine and cannot be altered or added to. The information consists of the numbers keyed in.

An electronic pocket calculator can perform almost instant arithmetic. A calculator requires an input unit to feed in numbers, a processing unit to make the calculation, a memory unit, and an output unit to display the result. The calculator is powered by a small battery or by a panel of solar cells. Inside is a microchip that contains the memory and processing units and also controls the input unit, which is the keyboard, and the output unit, which is the display.

The input unit has keys for numbers and operations. Beneath the key is a printed circuit board containing a set of contacts for each key. Pressing a key closes the contacts and sends a signal along a pair of lines in the circuit board to the processing unit, in which the binary code for that key is stored in the memory. The processing unit also sends the code to the display. Each key is connected by a different pair of lines to the processing unit, which repeatedly checks the lines to find out when a pair is linked by a key.

The memory unit stores the arithmetic instructions for the processing unit and holds the temporary results that occur during calculation. Storage cells in the memory unit hold the binary codes for the keys that have been pressed. The number codes, together with the operation code for the plus key, are held in temporary cells until the processing unit requires them.
When the equals key is pressed, it sends a signal to the processing unit. This takes the operation code-for example, addition-and the two numbers being held in the memory unit and performs the operation on the two numbers. A full adder does the addition, and the result goes to the decoder in the calculator's microchip. This code is then sent to the liquid crystal display unit, which shows the result, or output, of the calculation.

In what part of the calculator are the processing and memory units?

A. the battery

B. the solar cells

C. the output unit

D. the microchip
