70% to pass

In comparison to electric power, hydraulic power for jacking systems has the advantage of _______________.

A less preload needed
B less maintenance and repair
C fewer personnel needed during jacking
D better control capabilities
AI Explanation

The correct answer is D) better control capabilities. Hydraulic power for jacking systems generally provides better control capabilities compared to electric power. Hydraulic systems allow for more precise and responsive control over the jacking process, enabling finer adjustments and better overall control of the jacking operation. This is due to the inherent properties of hydraulic fluid, which can transmit force and power more efficiently and with greater precision than electrical systems. The other options are incorrect because they do not directly address the key advantage of hydraulic power over electric power for jacking systems, which is the improved control capabilities.
