Passage Summary: Food producers use radiation to keep food fresh longer. While some studies said this was safe, those studies were later debunked as being poorly done, so the activist claims the food is actually dangerous.

Conclusion: Irradiated food is not safe for human consumption.

Reasoning: The five studies that previously concluded irradiated food was safe were found by independent scientists to have serious methodological flaws.

Analysis: The activist commits a classic absence of evidence fallacy. Just because the evidence supporting a claim is shown to be unreliable doesn't mean the claim itself is false. The argument fails to consider that the food could still be safe, even if those specific studies didn't prove it. Look for an answer choice that describes this shift from unproven to disproven.
