根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两处为多余选项。

  1    First, the radioactivematerial must travel from its place of production to the power station.Although the power stations themselves are strongly built', the ．containers used for thetransport of the materials are not． 2 Unfortunately, both' of these may have an effect on the generalpublic, since they are sure to pass near, or even through heavily populatedareas．

Second, there is the problem of waste．  3   It is impossible to make these wastes non—radioactive,and so they must be stored in one of the inconvenient ways ．that scientists have invented．For example?they may be buried under the ground, or dropped into deserted mines, or sunk inthe sea．However, these methods do not 'solve theproblem, since an earthquake could easily break the containers．

Third, there may occur the danger of a leakor an explosion at the power station．As with the other two dangers, this is not verylikely to take place． 4   However, it can happen．

Separately, these three types of dangers arenot a great cause for worry．  5 

    A．It is unusual forradioactive materials to be transported across land．

    B．There are three separatesources of danger in supplying energy by nuclear power．

    C．All nuclear power stationsproduce wastes that in most cases will remain radioactive for thousands ofyears．

    D．The general public arestrongly against the nuclear program．

    E．So it does not provide aserious objection to the nuclear program．

  F．Normally, only two methodsof transport are in use, namely road or rail．

  G．But when they are takentogether, the probability of disaster is extremely high．
