In the United States the statistics for a person changing career paths is very high. It's something like an average person will change careers five times. Changing jobs is one thing, but completely changing careers is a big move. So this question is not that significant. If everyone worked in the industry as their major, then this question is more important, but because everyone changes jobs frequently, it's no big deal. You just have to use this opportunity to show them how much you like the current industry you are in.
This example does three things. It explains why this person is not going into a field related to their major, it is explaining why this person is going into logistics, and finally it is showing passion for the industry and a desire to learn. Since you are probably competing against people who majored in logistics, you need to make an impression with your answer. So you should definitely show enthusiasm here.
