Answer:
1.<u><em>Immediate impact of the Chernobyl accident. The accident caused the largest uncontrolled radioactive release into the environment ever recorded for any civilian operation, and large quantities of radioactive substances were released into the air for about 10 days.</em></u>
2.<u><em>The areas we identified as being significantly advanced following Chernobyl were: the importance of semi-natural ecosystems in human dose formation; the characterisation and environmental behaviour of ‘hot particles'; the development and application of countermeasures; the “fixation” and long term bioavailability of radiocaesium and; the effects of radiation on plants and animals.</em></u>
Both options A) and B) are used to identify sedimentary rock.
The conditions the rock was formed under & the composition of the rock itself are used to identify sedimentary rock.
B) when it was formed, does not make [identifying] a rock sufficient. Same goes for C) where it was formed, this may help with the identification of a different rock (i.e.,igneous rock), but not sedimentary. As sediments basically make up this type of rock.
