STAT - Special Tertiary Admissions Argument and Evidence Analysis Questions and Answers — Questions and Answers
Question 1: A political advertisement states: 'Candidate X has the most social media followers, so they are clearly the best choice for president.' Which logical fallacy is most evident in this statement?
- Straw Man
- Ad Hominem
- Bandwagon Fallacy (Ad Populum) (Correct answer)
- Slippery Slope
Correct answer: Bandwagon Fallacy (Ad Populum)
The Bandwagon Fallacy, or Argumentum ad Populum, asserts that something must be true or good simply because it is popular. This argument incorrectly equates popularity (number of social media followers) with qualification for office, which is the core of the fallacy.
Question 2: A study found a correlation between ice cream sales and the number of drownings. The conclusion drawn was that eating ice cream causes drowning. What is the primary flaw in this reasoning?
- The conclusion ignores a potential common cause for both phenomena. (Correct answer)
- The sample size of the study was not mentioned and is likely too small.
- The study demonstrates a causal relationship, not just a correlation.
- The evidence is anecdotal and not based on scientific observation.
Correct answer: The conclusion ignores a potential common cause for both phenomena.
This is a classic example of confusing correlation with causation. A third factor, such as hot weather, is a common cause that leads to both increased ice cream sales and more people swimming (which increases the risk of drowning). The argument incorrectly assumes a direct causal link without considering other variables.
Question 3: An argument is presented: 'All successful entrepreneurs work more than 60 hours a week. Sarah works more than 60 hours a week. Therefore, Sarah is a successful entrepreneur.' What is the unstated assumption required for this conclusion to be logically valid?
- People who are not entrepreneurs do not work more than 60 hours a week.
- Working more than 60 hours a week is the only requirement for being a successful entrepreneur.
- Sarah wants to be a successful entrepreneur.
- All people who work more than 60 hours a week are successful entrepreneurs. (Correct answer)
Correct answer: All people who work more than 60 hours a week are successful entrepreneurs.
The argument's structure is: If P (successful entrepreneur), then Q (works >60 hours). Sarah has Q. Therefore, Sarah has P. This is a logical fallacy (affirming the consequent) unless we assume the unstated premise that 'If Q, then P' (All people who work >60 hours are successful entrepreneurs). This assumption makes the conclusion logically follow from the premises.
Question 4: A city council member argues against a proposed bicycle lane project by stating, 'If we approve this bike lane, it's only a matter of time before activists demand we ban all cars from the city center.' Which of the following best describes this argumentative tactic?
- Red Herring
- Hasty Generalization
- False Dilemma
- Slippery Slope (Correct answer)
Correct answer: Slippery Slope
The Slippery Slope fallacy occurs when an argument claims that a relatively small first step will inevitably lead to a chain of related, negative events without sufficient evidence. The council member is suggesting that the single action of adding a bike lane will unavoidably lead to the extreme outcome of banning all cars.
Question 5: Which of the following pieces of evidence would most strongly support the claim that a new tutoring program is effective at improving student test scores?
- A collection of positive testimonials from students who enjoyed the program.
- A report showing that the program's lead tutor has a PhD in education.
- A controlled study showing that students in the program had a statistically significant greater score increase than a comparable group of students who were not in the program. (Correct answer)
- A newspaper article quoting the school principal saying the program is a 'resounding success'.
Correct answer: A controlled study showing that students in the program had a statistically significant greater score increase than a comparable group of students who were not in the program.
A controlled study provides the most robust and objective evidence. By comparing the results of a group that received the tutoring with a similar group that did not, it isolates the effect of the program itself, minimizing the influence of other factors. Testimonials are subjective, tutor qualifications don't guarantee results, and a principal's opinion is not empirical data.
Question 6: An op-ed argues that a country's economic problems are solely due to the policies of the current government, which has been in power for one year. In evaluating the strength of this argument, which question is most crucial to ask?
- What is the political affiliation of the op-ed's author?
- How many people have read and shared the op-ed online?
- What were the economic conditions and trends before the current government took office? (Correct answer)
- Does the current government plan to change its economic policies in the future?
Correct answer: What were the economic conditions and trends before the current government took office?
To evaluate the claim that the current government is solely responsible for economic problems, it is essential to consider the context and pre-existing conditions. Economic trends are often the result of long-term factors, and the previous state of the economy is a critical piece of evidence needed to assess the current government's actual impact.
