LNAT - Law National Aptitude Argument Component Identification Questions and Answers

Question 1

Read the following passage: 'The rise in popularity of electric vehicles is a positive step towards reducing carbon emissions. However, the environmental benefits are often overstated. The manufacturing of electric vehicle batteries is an energy-intensive process that relies heavily on the mining of rare earth minerals, which causes significant environmental degradation. Therefore, a wholesale shift to electric vehicles without addressing the battery production lifecycle may not be the panacea for climate change it is claimed to be.' Which of the following best identifies the main conclusion of the argument?

Accepted Answer

A complete transition to electric vehicles might not solve climate change if battery production issues are ignored.

Answer

The main conclusion is the central claim the author is trying to prove. The other statements are premises that support this conclusion. The passage acknowledges the benefits of electric vehicles but uses the evidence about battery manufacturing and mineral mining to argue that they are not a complete solution without further changes. The word 'Therefore' is a strong indicator of the main conclusion.

Question 2

An argument is presented: 'All successful entrepreneurs are risk-takers. Sarah is a successful entrepreneur. It follows that Sarah is a risk-taker.' What role does the statement 'Sarah is a successful entrepreneur' play in this argument?

Accepted Answer

A premise

Answer

A premise is a statement presented as a reason or evidence for a conclusion. In this deductive argument, 'All successful entrepreneurs are risk-takers' is the major premise, and 'Sarah is a successful entrepreneur' is the minor premise. Both are used to support the conclusion that 'Sarah is a risk-taker'.

Question 3

Consider the following statement: 'To curb inflation, the central bank must raise interest rates. This is because higher interest rates make borrowing more expensive, which reduces consumer spending and cools down the economy. While this may lead to a short-term economic slowdown, it is a necessary measure to ensure long-term price stability.' Which of the following is an unstated assumption made by the author?

Accepted Answer

The central bank has the authority to change interest rates.

Answer

An assumption is a belief that is taken for granted but not explicitly stated. The entire argument rests on the idea that the central bank has the power to implement the proposed solution (raising interest rates). The other options are either too extreme ('always', 'only') or are value judgments not essential to the argument's logical structure.

Question 4

A politician argues: 'My opponent's economic plan is flawed because he has changed his position on tax policy multiple times in the past. A person who cannot stick to one position cannot be trusted to manage the country's economy.' What is the primary flaw in this argument?

Accepted Answer

It attacks the opponent's character rather than the substance of their plan.

Answer

This is an example of an 'ad hominem' fallacy. The argument attacks the person (their perceived inconsistency) instead of engaging with the merits or weaknesses of the economic plan itself. The argument does not address any specific details of the opponent's plan.

Question 5

Read the passage: 'Many people believe that organic food is healthier than conventionally grown food because it is produced without synthetic pesticides. While it is true that pesticide residues can be harmful, numerous scientific studies have found no significant nutritional difference between organic and conventional produce. Therefore, the belief that organic food is inherently healthier is not strongly supported by scientific evidence.' Which component of an argument is the sentence 'numerous scientific studies have found no significant nutritional difference between organic and conventional produce'?

Accepted Answer

Evidence

Answer

This sentence provides factual information (the findings of scientific studies) to support the argument's main conclusion. Evidence consists of facts, statistics, or expert findings used to strengthen a claim.
