So in this question, we're going to be looking at this section on green chemistry.
00:07
So for a, there is evidence in this passage that this is correct.
00:13
The chemicals do need to be tested to ensure that they are safe after the r &d process.
00:26
So basically, after designing the safer chemical, the safety of the chemicals does need to be tested.
00:47
So it says right here, reach requires companies to submit human health and environment safety test data and an assessment of the risks of the chemicals.
01:07
So this is done near the end of the research and development process.
01:12
So they do need to be tested to ensure they are safe.
01:22
Now for b, this is also correct.
01:24
So this image here depicts an example of how chemists are able to modify the structure of a more harmful chemical to make it more green and thus more environmentally friendly and less likely to cause health issues...
