Q1 15

Question 1: A politician argues: 'If we raise the minimum wage by even one dollar, businesses will start laying off workers, then unemployment will skyrocket, the economy will collapse, and we'll end up in a full-scale depression.' Which logical fallacy does this argument exemplify?

Question 1 options
This is a slippery slope fallacy because the speaker chains a modest policy change to an extreme catastrophic outcome (economic depression) without providing evidence for each causal link in the sequence.
Q2 15

Question 2: In a persuasive essay, the writer states: 'If the university allows students to use laptops during lectures, next they'll be playing video games, then attendance will drop, and eventually the entire educational system will ___.' Which word best completes this slippery slope argument as typically constructed?

Question 2 options
The word 'collapse' fits the pattern of a slippery slope fallacy, which characteristically ends with an extreme, catastrophic outcome that is disproportionate to the initial scenario. Words like 'improve,' 'stabilize,' or 'adapt' would undermine the exaggerated chain of consequences essential to the fallacy.
Q3 15

Question 3: A slippery slope argument is always fallacious, regardless of whether the speaker provides credible evidence for each step in the causal chain.

Question 3 options
This is false. A slippery slope argument is only fallacious when the causal links between steps are unsupported or implausible. If each intermediate step is backed by strong evidence, the argument may be logically valid rather than fallacious.
Q4 15

Question 4: Which of the following sentences correctly demonstrates a slippery slope fallacy?

Question 4 options
The sentence about allowing one employee to work remotely leading to the entire company shutting down its offices and eventually going bankrupt is a slippery slope fallacy because it jumps from a minor accommodation to an extreme, unsupported catastrophic outcome through a chain of unsubstantiated causal links.
Q5 15

Question 5: Match each logical fallacy term to its correct definition or characteristic.

Question 5 options
Slippery slope
Ad hominem
Straw man
False dilemma
Attacks the person instead of addressing the argument
Claims one event inevitably causes extreme consequences
Presents only two options when more alternatives exist
Misrepresents an opponent's argument to refute it easily

Select an item on the left, then tap its match on the right.

A slippery slope claims one event leads to extreme consequences without evidence. Ad hominem attacks the person rather than the argument. A straw man distorts the opponent's position. A false dilemma presents only two options when more exist.
Q6 15

Question 6: Which of the following arguments contains a logical error specifically related to the slippery slope fallacy?

Question 6 options
The argument about allowing a student to retake one exam leading to nobody studying and the university losing accreditation is a slippery slope fallacy. It presents an unsupported chain from a minor accommodation to catastrophic institutional failure. The other options contain different fallacies: appeal to authority, false dilemma, and ad hominem respectively.
Q7 15

Question 7: In a formal academic essay analysing rhetorical strategies, which of the following sentences best identifies and introduces a slippery slope fallacy in the text being analysed? 'The author argues that legalising one recreational substance will inevitably lead to widespread addiction, societal decay, and the legalisation of all narcotics. This argument ___.'

Question 7 options
The phrase 'constitutes a slippery slope fallacy, as it posits an unsubstantiated chain of escalating consequences' is the best choice because it uses precise academic language, correctly names the fallacy, and explains why the reasoning is flawed — all essential for formal analytical writing.
Q8 15

Question 8: The following sentence contains a misidentified fallacy: 'When the senator claimed that permitting offshore drilling would lead to the destruction of all marine ecosystems, the collapse of coastal economies, and eventually the end of civilisation, the journalist correctly labelled this a straw man argument.' Which option correctly fixes the error?

Question 8 options
The senator's argument presents a chain of increasingly extreme consequences stemming from a single action (permitting offshore drilling), which is the defining characteristic of a slippery slope fallacy, not a straw man. A straw man involves misrepresenting someone else's position.
Q9 15

Question 9: Arrange the parts of a well-structured paragraph that identifies and refutes a slippery slope fallacy in the correct order:

Question 9 options
  • Therefore, the argument fails to demonstrate a plausible causal relationship between the initial action and the predicted outcome.
  • This line of reasoning exemplifies a classic slippery slope fallacy.
  • The mayor contends that allowing food trucks downtown will drive restaurants out of business, cause mass unemployment, and ultimately devastate the city's economy.
  • No credible evidence links the presence of food trucks to the cascading economic catastrophe the mayor describes, and each step in the chain is speculative.

Drag items or use arrows to arrange them in the correct order.

An effective analytical paragraph first presents the claim being examined, then identifies it as a slippery slope fallacy, next explains why the causal chain is unsupported, and finally provides a concluding assessment of the argument's validity.
Q10 15

Question 10: You are writing a formal report evaluating public policy arguments. A council member argued: 'If we build a new bike lane on Main Street, drivers will abandon the road, businesses will lose customers, and the entire commercial district will become a ghost town.' Which of the following is the most appropriate way to address this claim in your report?

Question 10 options
In a formal policy report, the most appropriate approach is to name the fallacy precisely, explain why the causal chain is unsupported, and maintain an objective, professional tone. The correct option achieves all three of these requirements.
Q11 15

Question 11: Which of the following best distinguishes a slippery slope fallacy from a false dilemma?

Question 11 options
A slippery slope fallacy asserts that a minor action will trigger a chain of events leading to a catastrophic outcome, while a false dilemma restricts the available options to only two, ignoring other possibilities. The key distinction is the chain of unsupported consequences versus the artificial limitation of choices.
Q12 15

Question 12: Which of the following versions is most appropriate for an academic essay analysing a politician's use of the slippery slope fallacy?

Question 12 options
Academic writing requires a formal, objective register that names the fallacy precisely and explains the logical flaw without colloquial language or emotional dismissals. The correct option uses appropriate academic phrasing such as 'predicates her argument upon' and 'unsubstantiated causal progression.'
Q13 15

Question 13: A slippery slope fallacy must always involve exactly three intermediate steps between the initial scenario and the final catastrophic outcome to be classified as such.

Question 13 options
This is false. A slippery slope fallacy has no fixed number of intermediate steps. The defining feature is the unsupported causal chain from a relatively innocuous starting point to an extreme outcome, regardless of how many steps are involved.
Q14 15

Question 14: A commentator writes: 'If we ban plastic straws, people will stop caring about personal freedom, authoritarian laws will multiply, and eventually we'll live in a totalitarian state.' Why does the writer use this chain of escalating consequences?

Question 14 options
The writer employs a slippery slope to instil fear about a minor environmental measure by linking it to an extreme political dystopia. The rhetorical effect is to provoke an emotional reaction — specifically fear — that discourages support for the initial, relatively benign proposal.
Q15 15

Question 15: The following sentence is awkward and imprecise: 'The debater said if we do one thing it will cause bad things and then even worse things, which is a fallacy of some kind.' Which revision best improves clarity, precision, and academic style?

Question 15 options
The best revision replaces vague language ('one thing,' 'bad things,' 'a fallacy of some kind') with specific, precise academic phrasing that names the fallacy, identifies the rhetorical strategy, and explains the logical flaw in a single well-constructed sentence.
