Cho is using technological design to build a clock based on the apparent motion of the Sun.

Which of the following would be the best measure of success for Cho's clock?
A.

B.
Cho's clock is small enough to be worn as a wrist watch.
C.
The time shown on Cho's clock is eleven hours ahead of the actual time.
D.

The correct answer is D. The time according to Cho's clock is very similar to the actual time.

Explanation:

The purpose of any clock is to display accurately the time of the day in a specific geographical location. This function applies to different types of clocks such as digital clocks, analog clocks, or sundials that use the motion of the Sun to determine the time. According to this, the best measure of success for Cho's clock, which is similar to sundials, is whether this clock tells accurately the time, which can be proven by comparing the time in Cho's clock and regular clocks.
