Question

Which of the following started out as a trademark name?

1) Zipper
2) Linoleum
3) Nylon
4) All the above

Answer 1

Zipper, linoleum, and nylon all began as trademark names, with the zipper patented as 'clasp locker' in 1893 and eventually becoming a common term as its use spread.

Step-by-step explanation:

The items mentioned in the question, zipper, linoleum, and nylon, all started out as trademark names. The zipper was initially patented in 1893 as the "clasp locker" but did not become widely used for several decades after its invention. The term zipper became more commonly used over time as the technology became pervasive in fashion and everyday use. Similarly, linoleum was once a brand name for a type of floor covering that has since become genericized. Nylon, created by DuPont, was also a brand name for a synthetic polymer used in a vast array of products, including fabrics and bristles.
