Examine the scenario.
In order to state that a substance causes cancer, scientists need to show the
mechanism by which this happens in a living organism and also demonstrate how
the substance specifically activates the mechanism.
A study of people whose diet contains Sweetener X shows that those people
have a much higher rate of cancers than people whose diet does not contain this
artificial sweetener. But the study does not provide any insight into how the
substance causes cancer.
For this reason, an announcer in a television documentary on artificial food
additives says, "Scientific studies do not show that Sweetener X causes cancer."
Which option correctly pairs the misunderstanding viewers will receive with the
reason why they will have that misunderstanding?
