Answer 2

Answer:

Significance has been given below:

Explanation:

fire: One of humanity's first great innovations was the discovery of fire, or, more precisely, the controlled use of fire. We can use fire to generate light and heat, cook plants and animals, clear forests for planting, heat-treat stone for making stone tools, keep predator animals at bay, and burn clay for ceramic objects.

wheel: While the basic function of the wheel remains the same, modern wheels are vastly different from the simple wooden wheels of yesteryear. Materials science advancements have enabled the development of a wide range of tyres for bicycles, automobiles, motorcycles, and trucks, including tyres designed for rough terrain, ice, and snow.

agriculture: Because there was more food available, this allowed for an evolution in society and in the daily lives of humans. Furthermore, communities grew as a result of the crops, which generated profits to meet food demands.

use of metals: Metals were used by prehistoric man to make tools and weapons, and as our understanding of metallurgy has grown, metals have played an important role in the advancement of agriculture, transportation, and arts and crafts, paving the way for today's modern society.
