Stimulus

The mathematics of the scientific theory known as “complexity” describes those phenomena that are not quite stable and not quite chaotic. For example, the mathematics of complexity can be used to describe sand dunes: although sand dunes generally retain their shape, the addition of a tiny amount of sand can cause a found that the computerized mathematical models evolve much like the real-world phenomena actually evolve.

What this question is testing

Principle-Strengthen

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.

Answer choices

  1. Correct73% picked this

    If computerized models based on a theory behave like their real-world counterparts behave, then that

    Why this is right

    This looks pretty stellar. Is the trigger applicable to complexity theory? Do computerized models based on complexity theory behave like their real-world counterparts behave? Yes, that's what the final sentence of the paragraph tells us. Okay, then according to this rule, "Complexity theory is probably correct". Does that help us justify the conclusion that "there is good evidence that complexity is correct"? Yeah, that sounds pretty close to the conclusion. It doesn't need to be identical to do a good job strengthening it.

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

  2. Reversed Logic18% picked this

    If a scientific theory is correct, then computerized mathematical models based on that theory behave

    This has similar ideas to (A), but they're in the wrong order. When we're trying to match a Principle to an Argument, we need the Trigger (left side) to match up with the evidence and the Outcome (right side) to match up with the conclusion. This answer is saying, "If conclusion, then premise".

  3. Bad Conclusion Match1% picked this

    If actual phenomena can be pictured as computerized models, computers themselves will eventually discover the mathematics of the

    This rule would help support a conclusion that "computers will eventually discover the math of the correct theory". We're trying to support a conclusion that says "there is good evidence that complexity is correct", so this outcome doesn't match our conclusion at all.

  4. Bad Conclusion Match7% picked this

    If they evolve exactly like real-world phenomena, computer models are neither purely stable nor purely chaotic, which

    This rule would help support a conclusion that "computers are nearly purely stable nor purely chaotic". We're trying to support a conclusion that says "there is good evidence that complexity is correct", so this outcome doesn't match our conclusion at all. The trigger is also not going to match, because we were told that the computer model was evolving much like the real-world phenomena, not exactly like them.

  5. Bad Conclusion Match0% picked this

    If computers verify that there are mathematical errors in the calculations of scientists, then the theories of those

    This rule would help support a conclusion that "this theory is probably incorrect". We're trying to support a conclusion that says "there is good evidence that complexity is correct", so this outcome is going the opposite way of what we're trying to prove.
