Answer:
When DVD players become obsolete 10 or 20 years from now, people won't have anything to help them remember this year of their lives.
Step-by-step explanation:
A supporting statement is one where the stated claim is supported and given validation by another statement. This is done to substantiate the claims or arguments presented in the original statement.
In the given statement, the claim is that the use of DVD instead of a "traditional yearbook" is, according to the speaker, "a terribly shortsighted one". This is because, in some years, the concept of DVD players will have become obsolete and new technological advances would have replaced them. This will render the DVD instead, while a traditional yearbook would have retained its contents no matter how many years pass. Moreover, the use of hard copies for yearbooks will allow a person to have easy access to its contents.
Thus, the claim that the DVD is a terribly shortsighted decision is supported by the fact that people won't have anything to hold on to for memories once DVD players become obsolete in a decade or two.
