The concept of conservation refers to the understanding that the amount of a substance remains the same even if its appearance or shape changes. In this situation, the twins lack the ability to conserve because they perceive the different glass shapes as having different amounts of milk, even though they contain the same amount. The other answer choices are not relevant to this situation.
