Why does the school bags have broad shoulder straps?(A) To increase pressure(B) To decrease pressure(C ) As a fashion trend(D) None of the above

The broad shoulder straps on school bags serve a functional purpose rather than being a fashion trend. The correct answer is (B) To decrease pressure.

Broad shoulder straps are designed to distribute the weight of the bag more evenly across the shoulders and back, reducing the pressure on any specific area. This helps to alleviate strain and discomfort, especially when students carry heavy textbooks and other items in their school bags. By providing a wider surface area, the broad shoulder straps help to prevent the straps from digging into the shoulders and causing pain or injury. They also help to improve the overall stability of the bag while it is being carried.

In summary, the main purpose of using broad shoulder straps on school bags is to decrease pressure and make carrying the bag more comfortable and ergonomic for the students.
