Answer: New evidence and machines allow scientists to get a more in depth look at cancer.
Step-by-step explanation:
Option A is incorrect because you cannot base scientific knowledge on the results of a single experiment. Also, the results will not be exactly the same as others but it should be close.
Option B is wrong because a scientific knowledge cannot change because someone decided that it should. Option D is incorrect as well because a persistent change needs to occur for scientific knowledge to be reviewed,
When new technology allows us to look further into things we were unable to look into before, knowledge will have a high chance of changing because we will now have more information to work with. Option C is therefore the best option.
