Put the paragraphs in order.
- AThomas Midgley started his career working on a major problem of the day, called 'engine knock', where fuel burnt in an uncontrolled explosion.
- BThese two chemicals gradually ate away at the atmosphere and poisoned millions of people's health for 50 years until their true impact was finally identified.
- CAt that time, additives could reduce the noise, but none effectively got rid of it, until Midgley realized that adding lead to petrol solved the problem completely.
- DHe then turned to refrigerators and was asked to work on safer alternatives to the toxic cooling chemicals used at that time, coming up with CFC gas as a solution.
