Aclothing manufacturer uses lasers to cut patterns in fabric when making t-shirts. which best describes a benefit of using lasers instead of traditional cutting machines?
laser machinery does not require energy.
laser machinery is safer because its light is weak.
lasers save time by cutting through more layers of fabric.
lasers result in fewer injuries because they quickly become blunt.

I believe the correct answer is the third option. One advantage of using lasers in cutting patterns instead of traditional cutting machines would be that lasers save time by cutting through more layers of fabric. Although it would cost some energy and the initial cost would be high, you would still be able to save some money as time goes by since you will be able to produce more for a certain period of time as compared to using traditional cutting methods for the same period of time. Also, by using lasers, you can cut complex patterns easily and you will need less people in the production.
