Contrast the effort required for six levels of quality of automobile to toothbrush OR SOME OTHER SIMPLE ITEM. You can select running shoes, ink pen, sun glasses, or any relatively simple product.

Contrast each quality level and effort required for automobile and simple item you select. Write down at least two pages discussing these comparisons.
