The most valuable resource that the Indians had to trade with the Europeans? A:Food
B:Deer Skins
C:Hunting Techniques
D:Building Styles

B. Deer skins.

Why? Probably because back in the days Indians used to be extremely talented when it came to hunting for food, water, and even warmth. I doubt they'd have tools to spare besides bows and most likely rock knives they've hand made to cut down the bone and other stuff to make seasonings with. Building styles? No. Why would the Europeans ask Indians to trade building techniques? I doubt it. B is definitely the answer.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
