To what should future predictions be based according to the measurable reference model?

• A. Past history, not current trends.
• B. Current trends only.
• C. Random data.
• D. Personal opinion.

Answer: (A)

Predictions should be grounded in verifiable data from the past, because a measurable reference model uses historical measurements to establish what’s normal and expected. Past history captures long‑term behavior and variability, giving a stable baseline that supports meaningful statistical forecasting and deviation detection. Relying on current trends alone can mislead, since short‑term fluctuations, anomalies, or recent events may not persist. Data that’s random offers no reliable signal, and personal opinion isn’t measurable evidence. Therefore, future predictions are based on past history.
