If onset is slow, the duration is:

If onset is slow, the duration is:

• A. Long
• B. Short
• C. Unchanged
• D. Increasing

Answer: (A)

When onset is slow, the process unfolds gradually, and the factors driving that activation often also slow down its return to baseline. This means once the effect starts, it tends to persist longer before fading, giving a longer duration. A short duration would require rapid activation and quick decline, which isn’t implied by a slow onset. An unchanged duration would ignore the kinetic implications of a slow start, and an increasing duration suggests a continual growth beyond the initial effect, which isn’t the typical interpretation here. So the best fit is a long duration.
