A Scientist argues that the risk to humans from eating genetically engineered foodstuffs is minimal. This is because mostly only one gene of 750,000 is changed, and such a small change cannot pose significant issues.

The Scientist assumes that just because the number of genetic changes is so small, the change to the organism will also be small and not pose a significant risk. It could be that a major change is sparked by altering a single gene.

This is irrelevant to the argument’s reasoning. The argument is focused on the impact of a single gene.

While this acknowledges that the risk could be minimized, it does not impact the key reasoning in the argument. The main claim is that the risks of GMOs are minimal because only slight changes are made.

This is irrelevant to the argument. The reasoning is focused on how many changes there are, not the location of certain genes.

This directly undermines the reasoning by showing that altering a single gene can have serious consequences. Thus, it weakens the argument.

The argument is not focused on whether those opposed to GMOs are ill-informed or not. This is completely separate from the argument’s reasoning.
