Which of the following is NOT an advantage of an electronic spark control system?
A) It compensates for changes in engine (and sometimes outside air) temperature
B) It allows lower compression ratio engines to be equally as efficient as higher compression ratio engines
C) It makes changes many times faster than older (mechanical) systems
D) It has a feedback mechanism in which sensor readings allow it to constantly compensate for changing conditions

Question
