If a system requires the gear shift to be within 65-75%, which term best describes this requirement?

• A. gearbox shift range
• B. gen cut-in range
• C. reference range
• D. overlap range

Answer: (A)

The idea here is specifying the allowed window for a control action. When a system requires the gear shift to be within a certain interval, that interval is best described as the gearbox shift range—the span of input values that define when shifting is permitted or expected. Why this fits best: the term directly names the specific action (gearbox shifting) and the precise operating window (65% to 75%). It communicates that shifting should occur only within that range. The other terms don’t match as well. A generator cut-in range would refer to when a generator starts operating, not gear shifting. A reference range is a general target or acceptable bounds for a parameter, but it’s not specifically about the gearbox act of shifting. An overlap range describes a shared region between two ranges, which isn’t what this requirement is describing.
