You use a reusable cup or bottle to drink the recommended 64 oz. (1/2 gallon) of water per day. You drink filtered tap water – the filter can make up to 80 gallons of clean water. How many days of clean drinking water will you get before you need a new filter?

a) 64 days
b) 80 days
c) 160 days
d) 200 days

Answer: C - 160 days.

1 gal = 128 oz
80 gal = 10,240 oz of water can be filtered
64 oz is the daily recommendation
10,240 / 64 = 160 days of filtered H20

When hiking in cold weather, you should layer your clothing with different types of fabrics to stay dry and warm. Which type of fabric should be avoided?

A) Nylon
B) Wool or fleece
C) Water-wicking synthetics
D) Cotton

Answer: D – Cotton. The clothing layers should consist of several different types of fabrics. Cotton should be avoided in cold conditions. Cotton absorbs and retains water, and therefore it will not keep you warm if it gets wet. Also it can be difficult to dry. Polypropylene or other hydrophobic synthetic fabrics move the moisture (sweat) away from your body to the outside of the layer, reducing evaporative cooling and keeping you dry and comfortable. Wool or synthetic pile/fleece fabrics don't absorb water so they keep you warm even if they get wet. Pile also dries very quickly. A wool sweater or pile jacket provides warmth on a chilly evening. Nylon or Nylon/Cotton Windshells reduce convective heat loss. For raingear, coated nylon is lightweight and works well. Waterproof-breathable fabrics are also possible but are expensive.
