Which of the following is NOT made using fiber crops?

Fiber crops are primarily cultivated for their fibers, which can be extracted and processed into a variety of materials used in everyday products. Paper, cloth, and rope are all traditionally manufactured from fiber crops.

Paper is made from the cellulose fibers found in plants such as cotton, which is indeed a fiber crop. Similarly, cloth is often made from fibers derived from cotton and other textiles, like linen from flax, and jute. Rope is also commonly produced from natural fibers, including hemp and sisal, both of which are classified as fiber crops.

In contrast, grocery bags, especially those that are designed to be biodegradable or environmentally friendly, are often made from materials like plastic or recycled paper rather than directly from fiber crops. While some grocery bags can be made of paper (which is derived from fiber crops), when referring to standard plastic grocery bags, they are not made from fiber crops at all, highlighting that grocery bags are not exclusively tied to fiber production in the way that paper, cloth, and rope are. This distinction makes grocery bags the correct choice as the item that is not exclusively made using fiber crops.
