Introduction / Context:
The statement merely warns that computer systems could be affected at the millennium rollover. We test whether it presumes sadness or a guaranteed solution.

Given Data:

Concept / Approach:
An assumption must be necessary for the statement to be meaningful.

Step-by-Step Solution:
I: “Will be sad” is an emotional inference not required for a technical warning. Not implicit.II: The existence or efficacy of specialists is not presupposed by the warning itself. Not implicit.

Verification / Alternative check:
A warning stands regardless of whether a fix exists or people feel sad.
