Which example best illustrates a slippery slope argument?

A slippery slope argument suggests that a relatively small first step can lead to a chain of related events culminating in a significant (often negative) effect. In this case, the scenario presented indicates that allowing students to redo tests may lead to increased expectations for leniency across all aspects of grading. This line of reasoning demonstrates the essence of slippery slope logic, as it implies that one policy change will inevitably lead to further, possibly undesirable changes without providing evidence to support such conclusions. The concern is that if leniency is granted in one area, it will spiral out of control, affecting broader educational policies.

The other examples do not illustrate slippery slope arguments. The second choice discusses the principle of differing opinions without implying a causal chain of events. The third option presents an anecdote about an individual’s health, which does not involve progression from one situation to another. The fourth choice, while suggesting a potential conflict between educational focus areas, does not indicate that one action will lead to a series of negative consequences in the same way as the first option.
