Stimulus

The area of mathematics called "gauge field theory," though investigated in the nineteenth century, has only relatively recently been applied to problems in contemporary quantum mechanics. Differential geometry, another area of mathematics, was investigated by Gauss in the early nineteenth century, long before Einstein was the appropriate mathematics for exploring general relativity.

What this question is testing

Most Supported

Your task

Break the argument into its conclusion and evidence, then do exactly what the question stem asks with that structure.

Common trap

Answers that sound relevant to the topic but don't connect to the argument's actual reasoning.

Winning move

Predict what a right answer must do, then test each choice against the conclusion-evidence gap.

Which one of the following is best illustrated by the examples

Answer choices

  1. Correct87% picked this

    Applications of some new theories or techniques in mathematics are unrecognized until long after the discovery of

    Why this is right

    This statement mirrors the relationship between the two examples.

    Skill tested: Most Supported · how this choice captures the argument's function is the move to repeat next time.

  2. Half Scope / Unsupported Relationship4% picked this

    Mathematicians are sometimes able to anticipate which branches of their subject will prove useful

    The first example does not mention mathematicians. Furthermore, Gauss did not anticipate that tensor analysis would be useful to future scientists.

  3. Too Strong6% picked this

    The discoveries of modern physics would not have been possible without major mathematical advances made

    The examples establish that some areas of modern physics have benefited from mathematical advances made in the nineteenth century, but to say that the discoveries of modern physics would not have occurred without those mathematical advances goes too far.

  4. Unsupported Comparison2% picked this

    The nineteenth century stands out among other times as a period of

    Nothing in the examples would permit a comparison between the mathematical advances of the nineteenth century and those of other centuries.

  5. Unsupported Comparison1% picked this

    Mathematics tends to advance more quickly than any of the

    Nothing in the examples would permit a comparison between the rate at which mathematics advances and the rates of other physical sciences.
