What happens to the material removal rate if the sparks are very less

1.	What happens to the material removal rate if the sparks are very less in EDM?(a) Decreases(b) Increases(c) Increase and then decrease(d) All of the mentionedI have been asked this question during an internship interview.My question is taken from EDM-Material Removal Rate in division Thermal Processes of Advanced Machining
Answer» The correct CHOICE is (a) Decreases For EXPLANATION I would say: In EDM, if SPARKS generated are less then material removal RATE decreases.
