Question

Which substance provides the most strength for a given thickness of fiber?
A. spider milk
B. nylon fiber

Answer 1

When comparing the strength of different materials, nylon fiber is generally known for its strength and durability among synthetic fibers. Spider silk, particularly that from certain species of spiders, is often cited as one of the strongest natural materials in terms of tensile strength relative to its thickness.

If comparing the two options specifically on the basis of strength for a given thickness of fiber, spider silk is known to have remarkable strength-to-weight ratios and is often stronger than nylon fiber when considering equal thicknesses.

So, the answer would be **A. spider silk**.
