Match the correct word to the blanks listed below to ensure that the paragraph would be coherent. -- There are three separate sources of hazard related to the use of nuclear reactions to supply us with energy. ___A_______, the radioactive material must travel from its place of manufacture to the power station. _____B_____ the power stations themselves are solidly built, the containers used for the transport of the material are not. _____C_____, there are normally only two methods of transport available, _____D_____ road or rail, and both of these involve close contact with the general public, _____E_____ the routes are bound to pass near, or even through, heavily populated areas. ____F______, there is the problem of waste. All nuclear power stations produce wastes which in most cases will remain radioactive for thousands of years. It is impossible to de-activate these wastes, and ______G____ they must be stored in one of the ingenious but cumbersome ways that scientists have invented. ______H____ they may be buried under the ground, dropped into disused mineshafts, or sunk in the sea. _______I___ these methods do not solve the problem; they merely store it, _____J_____ an earthquake could crack open the containers like nuts. _____K_____ there is the problem of accidental exposure due to a leak or an explosion at the power station. As with the other two hazards, this is extremely unlikely and ______L____ does not provide a serious objection to the nuclear programme, ___M_______ it can happen, as the inhabitants of Harrisburg will tell you. Separately, and during short periods, these three types of risk are no great cause for concern. Taken together, ____N______, and especially over much longer periods, the probability of a disaster is extremely high. *
