Question

Which two details refine the author's claim that the materials used for the design of shoes has evolved over time? excerpt from “Shoes: Feet First!” from A History of Travel in 50 Vehicles by Paula Grey & Phillip Hoose Despite the relatively recent age of the early shoes found to date, scientists believe that humans were wearing shoes as much as 40,000 years ago. Shoes made of reeds, papyrus, or even leather decompose easily, leaving few or no traces. But people who don’t wear shoes have wider feet and bigger gaps between their big toe and the other four. In studying bones of the smaller toes of fossilized skeletons, scientists observed that the thickness of these bones decreased somewhere between 40,000 and 26,000 years ago. They believe the change was the result of wearing shoes. The materials used to make shoes varied with the climate and region. Ancient Egyptians made sandals from papyrus and palm leaves. The Masai of Africa used rawhide; the people of India used wood; and the Chinese and Japanese used rice straw. South Americans wove sandals from the leaves the sisal plant, and the Anasazi people of Mexico and Arizona used the yucca plant. The Dutch developed wooden clogs. People living in arctic climates created snowshoes —a hardwood frame with rawhide lacings—which distribute a person’s weight over a larger area so that the foot doesn’t sink into the snow. Today, shoe manufacturers use rubber, plastic, cloth, and other materials in addition to leather. Most soles are made from synthetic materials such as ethylene, vinyl, acetate, rubber, and polyurethane, which provide better traction, durability, and water resistance than leather soles. Special shoes are available for running, bowling, and other sports. And shoes are often considered an important fashion accessory.

Answer 1

The two details which refines the author's claim that the materials used for the design of shoes has evolved over time are where he mentions that there has been a change from the material used to make the shoes to more durable and resistant material.

According to the given question, we are asked to state the two details which refines the author's claim that the materials used for the design of shoes has evolved over time

As a result of this, we can see that from the given excerpt, there is the mention that human feet has evolved and has become bigger than they once were and this has led to the new materials which would make the shoes more durable and able to last longer.

Answer 2

Answer:

South Americans wove sandals from the leaves the sisal plant, and the Anasazi people of Mexico and Arizona used the yucca plant.

And

Most soles are made from synthetic materials such as ethylene, vinyl, acetate, rubber, and polyurethane, which provide better traction, durability, and water resistance than leather soles.

Explanation:

These answers best explained how shoes were made, and differed from different places all around the world. By using the surrounding words and context, the South Americans, and Anasazi people using different materials (due to weather conditions and etc) shows change! And in the second answer materials such as "ethylene, vinyl, acetate, rubber, and polyurethane" show that humans are evolving and making use of new material, with support by "better traction, durability, water resistance"! :)

I hope this helped?
