LNAT Critical Analysis 4

Question 1

A passage argues: 'Allowing euthanasia will lead to pressure on the elderly to end their lives, then to killing disabled people, then eventually to state-mandated death.' This is an example of:

Accepted Answer

Slippery slope fallacy

Answer

The argument assumes each step will inevitably lead to the next without providing evidence for that chain of causation.

Question 2

Which of the following is the best definition of a 'sound' argument?

Accepted Answer

An argument that is both valid and has all true premises

Answer

A sound argument must be logically valid (conclusion follows from premises) and all its premises must actually be true.

Question 3

A researcher finds that schools with more computers have better test results. The local government then buys computers for all failing schools. What assumption underlies this decision?

Accepted Answer

The correlation between computers and results is causal, not merely associative

Answer

The government assumes computers cause better results, but the association could be explained by other variables like school funding or demographics.

Question 4

Which of the following is NOT a legitimate way to strengthen an inductive argument?

Accepted Answer

Defining terms more precisely in the conclusion

Answer

Redefining terms in the conclusion does not add evidential weight; strengthening inductive arguments requires better evidence, not linguistic adjustments.

Question 5

A politician says: 'My opponent voted against the defense budget, which shows he wants our country to be attacked.' What rhetorical technique is being used?

Accepted Answer

Unwarranted inference / straw man

Answer

Voting against a specific budget does not logically entail wanting the country to be attacked; the politician fabricates an extreme motive.
