Which of the following did the new settlers introduce to the Indians?

When the early settlers, especially the British, arrived in the New World, the hardships and dangers awaiting them were totally unexpected. Had it not been for some friendly Indians, the colonists never would have survived the terrible winters. They knew nothing about planting crops, hunting animals, building sod houses, or making clothe from animal skins. Life in England had been much simpler, and this new life was not like what they had expected.
   The settlers did introduce iron tools, muskets for hunting, domesticated animals, and political ways to the Indians. In exchange, the settlers learned to build canoes for water transportation and snowshoes and toboggans for winter traveling. The Indians also taught them to blaze trails through the forest, to hunt large animals and trap smaller ones, and to spear fish in the lakes and streams.
   The natives also introduced to the settlers typical foods such as turkey, corn, squash, beans, and pumpkin. Everything possible was done in order to make their new settlement resemble the homes they had left behind.
