Inez: Space-exploration programs pay for themselves many times over, since such programs result in technological advances with everyday, practical applications.
Inez's Argument
We must invest in space exploration because it produces useful technological advances.
Winona's Move
Winona doesn't deny the technological advances. She points out that if those advances are the actual goal, the goal could be achieved more directly — by funding technology development directly, without space exploration.
Method
Winona attacks Inez's justification by showing the goal Inez cites can be pursued without the program Inez wants to fund.
Goal
An answer describing this method: claiming that the goal Inez mentions could be pursued through alternative means.
