C. the amount of time it takes to obtain imported flowers
A shade<span> is what one ends up with when black (or some other dark color) is added to a pure hue. Suppose you had some green paint and mixed a bit of dark gray paint into it. The resulting paint would be darker than (also known as a </span>shade<span> of) the original green. Think of a dazzlingly sunny day with intense color all around, then picture the way the light and colors change when you place yourself under the leafy </span>shade<span> of a tree.</span>
