In exhibit 5 of the reading (Accuracy in Validation and Training Samples vs. Training Sample Size), the training accuracy rate and the validation accurancy rate converge ______ the desired accuracy rate when there is a good trade-off between bias and variance error.

A. below
B. above
C. toward

Correct Answer: C

The learning problem itself is basically a trade-off between bias and variance. They don't converge above the desired accuracy rate, no matter how well the model is built.
