Answer:
The construction of a new science building on campus.
Explanation:
In the message, the reason the board of regents gives for increasing the tuition is that they did it in order to fund the construction of a new science building on campus.
This implies that if there was no need to construct a new science building on campus, there would not have been an increase in tuition.
Therefore, the regent's message places blame for the tuition increase on the construction of a new science building on campus.
