Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to survive in the desert [title] Wear clothing that minimizes sweat loss. [step] Most of your body's water loss happens through perspiration. Cover as much skin as possible with loose, light-weight clothing.

Ending1: If you want to survive in the desert, you need to keep yourself covered while hiking. [substeps] If you're not wearing tight-fitting clothes, the natural oils that come from the sun can permanently dry out your skin. Ending2: Fabrics that absorb water, such as cotton, sweat less, and are easy to wash. If you do not like wearing cotton clothing, then you can use cotton swabs to block sweat and dampness. Ending3: Include this type of clothing in most physiological activities, such as driving, water skiing, and prolonged manual travel. [substeps] Avoid loose cotton clothes and tight clothing. Ending4: This will trap the sweat against your skin, slowing evaporation and therefore water loss. For this reason, it's probably best to go with a cotton undershirt rather than a wicking fabric.
