Choices that help define the construct system

A) have a high predictive efficiency.
B) reject the secure choice.
C) represent the high risk/high reward choice.
D) reject intellect in favor of emotion.

Choices that have a high predictive efficiency are more likely to accurately represent and define the construct system. This means that these choices are better at predicting behavior and outcomes, which is an important factor in understanding and defining a construct system. Rejecting the secure choice, representing the high risk/high reward choice, and rejecting intellect in favor of emotion may be factors that contribute to the construct system, but they do not necessarily provide the same level of predictive efficiency as choice A.
