Let S be the set of maximally specific hypotheses. While iterating through the dataset, when is it changed for the first time? Correct Answer Positive example is encountered for the first time

The most specific hypothesis states that any example is a negative example. So, it changes the first time when it encounters the first positive example. It takes the values of each attribute in the positive example.

We have been given a dataset with n records in which we have input attribute as x and output attribute as y. Suppose we use a linear regression method to model this data. To test our linear regressor, we split the data in training set and test set randomly. Now we increase the training set size gradually. As the training set size increases, what do you expect will happen with the mean training error?
