Answer :
The two points that further support the author's assertion that the materials used to create shoes have changed over time are when he says that more resilient and durable materials have replaced the original ones.
The author claims that the materials used to create shoes have changed over time, and the question asks us to elaborate on these two points. A last is necessary before a shoe can be produced. This is the physical foundation for the construction of your shoes. To give the shoe its shape, a shoe last is a mold that looks like a foot.
Originally made of wood, these are now also made of plastic and metal. A last is required for every left and right shoe in order to establish its shape and size. However, a last is not just a haphazardly foot-shaped piece of wood, and there are other considerations to make when making one. This includes the way a foot rolls while walking and how this affects elements like heel height. Due to this, we can see that the passage mentions how human feet have changed and grown larger than they previously were, which has resulted in the development of new materials that would make shoes more durable and able to last longer.

Correct 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.
