1. A system of trial by jury ensures that common-sense community standards are applied to legal disputes, making the law more democratic. However, legal cases have become incredibly complex, involving intricate financial instruments or advanced forensics. If a jury cannot understand the evidence, their verdict is essentially a lottery. Therefore, complex trials should be decided by judges alone. Which of the following, if true, most weakens the argument?

   • Judges are often older and less demographically representative than juries.
   • Expert witnesses can explain complex evidence in terms that laypeople can understand.
   • Jury trials are more expensive and time-consuming than trials by a single judge.
   • Many jurors report enjoying their service and finding it educational.
   Show answer & explanation

   Answer: B. Expert witnesses can explain complex evidence in terms that laypeople can understand.

   If expert witnesses can explain complex evidence clearly to laypeople, the premise that juries cannot understand the evidence is undermined, weakening the conclusion that judges should decide.

2. Proponents of a carbon tax argue that it is the most efficient way to reduce emissions because it uses market forces. However, a carbon tax disproportionately harms low-income households, who spend a larger percentage of their income on heating and fuel. Since any policy that increases inequality is unacceptable, we must reject the carbon tax in favor of direct government regulation of industrial emissions. Which of the following is an underlying assumption of the author's argument?

   • Direct government regulation of industrial emissions will not disproportionately affect low-income households.
   • Industrial emissions are the primary driver of global climate change.
   • A carbon tax would not succeed in reducing overall carbon emissions.
   • Low-income households are more concerned about economic survival than environmental protection.
   Show answer & explanation

   Answer: A. Direct government regulation of industrial emissions will not disproportionately affect low-income households.

   The author rejects the carbon tax because it increases inequality and concludes that we should use direct regulation instead. For this conclusion to stand, the author must assume that direct regulation does not also cause similar or worse inequality.

3. If a citizen has nothing to hide, they should have no objection to government surveillance. Conversely, if a citizen objects to government surveillance, they must have something illegal to hide. What is the logical flaw in the above reasoning?

   • It assumes that government surveillance is always highly effective at catching criminals.
   • It presents a false dichotomy by ignoring the possibility that citizens may value privacy for reasons unrelated to illegal activity.
   • It conflates the legality of an action with its morality.
   • It relies on a slippery slope argument that surveillance will inevitably lead to tyranny.
   Show answer & explanation

   Answer: B. It presents a false dichotomy by ignoring the possibility that citizens may value privacy for reasons unrelated to illegal activity.

   The argument assumes there are only two possibilities: either you have something illegal to hide, or you have no objection to surveillance. It ignores a third option—that law-abiding citizens may value privacy for personal, professional, or ethical reasons.

4. History shows that every major technological revolution—from the steam engine to the internet—has initially caused panic about job losses, yet ultimately created more jobs than it destroyed. Artificial Intelligence (AI) will be no different. We should therefore resist calls to regulate AI development heavily, as regulation will only slow down economic growth. Which of the following is the best statement of the main conclusion of the passage?

   • Artificial Intelligence will create more jobs than it destroys.
   • Heavy regulation of AI should be avoided because it will slow down economic growth.
   • Technological revolutions always lead to economic growth and job creation.
   • History proves that fear of technological advancement is always irrational.
   Show answer & explanation

   Answer: B. Heavy regulation of AI should be avoided because it will slow down economic growth.

   The main conclusion is the ultimate point the author is trying to establish. It is presented in the final sentence: 'We should therefore resist calls to regulate AI development heavily...'

5. Over the past thirty years, the percentage of the population holding a university degree has tripled. Over the same period, average entry-level salaries for professional jobs have stagnated when adjusted for inflation. This demonstrates that a university degree is no longer a reliable pathway to economic mobility. Which of the following, if true, most seriously weakens the argument?

   • The cost of attending university has risen faster than inflation over the past thirty years.
   • The average salary of individuals without a university degree has declined significantly over the past thirty years.
   • Many universities now offer online degrees that are less prestigious than traditional degrees.
   • Most employers still list a university degree as a minimum requirement for entry-level professional jobs.
   Show answer & explanation

   Answer: B. The average salary of individuals without a university degree has declined significantly over the past thirty years.

   If the average salary of those without a degree has declined significantly, then a degree still provides a critical relative economic advantage and pathway to mobility, even if entry-level professional salaries stagnated.

6. Neuroscience increasingly shows that human behavior is determined by neurological processes beyond our conscious control. If free will is an illusion, then retribution—punishing people because they deserve it—is morally indefensible. The criminal justice system must therefore shift its focus entirely from retribution to rehabilitation and deterrence. Which of the following is a necessary assumption of the author's argument?

   • Rehabilitation and deterrence do not rely on the concept of free will to be effective or morally justified.
   • Retribution is the only current goal of the modern criminal justice system.
   • Neurological processes can be completely altered through rehabilitation programs.
   • People who commit crimes always want to be rehabilitated.
   Show answer & explanation

   Answer: A. Rehabilitation and deterrence do not rely on the concept of free will to be effective or morally justified.

   The author argues that because free will is an illusion, retribution is indefensible, and therefore the system must shift to rehabilitation and deterrence. This assumes that rehabilitation and deterrence do not themselves depend on the existence of free will for their moral or practical justification.

7. Sixteen-year-olds are allowed to work, pay income tax, and drive in many jurisdictions. Since they contribute to society and are subject to its laws, they should have the right to vote. Excluding them from the franchise is taxation without representation. Which of the following statements, if true, would most strengthen the argument?

   • Most sixteen-year-olds do not earn enough income to pay substantial income tax.
   • The average age at which people finish their education has increased over time.
   • Studies show that sixteen- and seventeen-year-olds possess the same cognitive capacity for political decision-making as eighteen-year-olds.
   • Many older voters do not pay income tax because they are retired.
   Show answer & explanation

   Answer: C. Studies show that sixteen- and seventeen-year-olds possess the same cognitive capacity for political decision-making as eighteen-year-olds.

   A common objection to lowering the voting age is cognitive maturity. Proving that 16- and 17-year-olds have the same cognitive capacity for political decisions as 18-year-olds directly strengthens their qualification for the franchise.

8. To combat obesity, the government should introduce a tax on high-sugar foods. When a similar tax was introduced on tobacco products, smoking rates fell dramatically. Therefore, a sugar tax will lead to a healthier population. The argument relies on which of the following analogies?

   • The addictive nature of sugar is identical to the addictive nature of nicotine.
   • High-sugar foods can be regulated in exactly the same way as tobacco products.
   • A reduction in smoking rates is equivalent to an increase in overall public health.
   • The consumer response to a price increase in sugar will mirror the consumer response to a price increase in tobacco.
   Show answer & explanation

   Answer: D. The consumer response to a price increase in sugar will mirror the consumer response to a price increase in tobacco.

   For the conclusion (sugar tax will work) to follow from the premise (tobacco tax worked), one must assume that consumers will react to a sugar tax in a structurally similar way to how they reacted to the tobacco tax.
