Which of the following is the best example of an inferior good? a. leather gloves b. a bus ride c. a dvd d. hiking boots

I think the answer is A. "A bus ride."

In economics, an inferior good is a good whose quantity demanded decreases when consumer income rises (or quantity demanded rises when consumer income decreases), unlike normal goods, for which the opposite is observed. Normal goods are those for which consumers' demand increases when their income increases 

The goods the europeans wanted the most were gold, jewels, silk, perfumes, and especially spices.
