Final answer:
The fiber content on clothing labels must be listed in descending order (option 3) by law, mirroring the required arrangement of ingredients on nutrition facts labels for food products.
Step-by-step explanation:
The question refers to the requirements for labeling the fiber content in clothing. According to the law, the fiber content on permanent labels in clothing must be listed in descending order. This is similar to how ingredients in food products are required to be listed on nutrition facts labels. When you read a nutrition facts label, the ingredients are arranged from the largest amount to the smallest, which helps consumers understand what they are consuming in greater quantities.
When choosing products, whether clothing for its material content or food for its nutritional value, it is essential to look for high-quality components. In food, it's beneficial to choose items containing whole grains, vegetables, and fruits, and to avoid processed ingredients that offer fewer nutrients. Similarly, when considering clothing, understanding the fiber content can influence decision-making regarding comfort, durability, and care of the garment.
