Ordering of Sentences Directions:In the following items each passage consists of six sentences. The first and the sixth sentence are given in the beginning. The middle four sentences in each have been removed and jumbled up. These are labelled P, Q R and S. You are required to find out the proper sequence of the four sentences.
Make sure that the interlocking device is not tampered with or inactivated. Several countries, as well as the International Electrotechnical Commission (IEC), the International Committee on Electromagnetic Safety (ICES) of the Institute of Electrical and Electronics Engineers (IEEE) and the European Committee for Electrotechnical Standardization (CENELEC), have set a product emission limit of 50 watts per square metre (W/m2) at any point 5 cm away from the external surfaces of the oven. In practice, emissions from modern domestic microwave ovens are substantially below this international limit, and have interlocks that prevent people being exposed to microwaves while the oven is on. Moreover, exposure decreases rapidly with distance; e.g. a person 50 cm from the oven receives about one one hundredth of the microwave exposure of a person 5 cm away.
