Which technological advancements were transferred to the Americas during the era of exploration?

The correct choice highlights key technological advancements that significantly impacted the development of societies in the Americas during the era of exploration. The wheel, iron implements, and guns represent foundational technologies that transformed transportation, agriculture, and military capabilities in the New World.

The wheel, despite its earlier invention, was not commonly used in the Americas prior to European contact. Its introduction facilitated improved transportation and trade networks among Native Americans. Iron implements greatly enhanced agricultural practices, making farming more efficient and allowing for the more effective clearing of land and cultivation. The introduction of guns changed the power dynamics significantly, providing European explorers and settlers with advantages in conflicts with Indigenous peoples.

In contrast, the other choices either include technologies that had limited impact during this particular era or were not transferred during the early periods of exploration. For instance, the printing press and clocks played crucial roles later in European societies, but their influence on the initial exploration and colonization phase is minimal. Textiles and glassmaking were important technologies but were not among the more transformative advancements that altered native ways of life in the Americas. Lastly, steam engines and electricity are products of much later technological developments and were not available during the era of exploration in the 15th and 16th centuries. Thus, identifying the significant and
