    If students spend a significant amount of time outside of class studying mathematics, the current crisis in mathematics

    This reverses the inference SOC → OC of the second and third statements.

  2. Correct70% picked this

    The current crisis in mathematics education will not be overcome unless students spend a significant amount of time

    Why this is right

    This follows from OC → STM the second and STM → SOC third statements. ჻ OC → SOC

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

  3. Unsupported Comparison1% picked this

    Few subjects are as important as mathematics to the effort to remain competitive in

    A comparison of the significance of mathematics to other subjects is not supported by statements.

  4. Reversed Inference3% picked this

    Only if we succeed in remaining competitive in the global economy will students spend a significant amount of time

    This reverses the inference SOC → RC that could be made from combining all three statements.

  5. Unsupported Relationship19% picked this

    Students' spending a significant amount of time outside of class studying mathematics would help us to remain competitive

    This suggests that the relationship is causal and that meeting a requirement of remaining competitive would actually help us to remain competitive.
