Sir, please help me to understand the reason for the following answer. It is supposed to be right: More attention to R&D costs in year 20XX could reduce warranty costs in subsequent years. Why is it necessary for more R&D to reduce warranty costs? In my understanding, R&D might reduce but might also NOT to reduce warranty costs in future… or we should just think in a way that if it is possible that it COULD reduce then the statement is right. I am just worring about how the quiestion is arranged.
