Which event is given as an example of discovery?

• A. Columbus discovering North America
• B. The space shuttle launch
• C. The invention of the telephone
• D. The printing press

Answer: (A)

Discovery means finding something that exists but was not known to the observer before. Columbus’s voyage fits this idea because it revealed to Europeans a large landmass in the Western Hemisphere that they did not know existed, reshaping maps, trade, and world history. The space shuttle launch is about applying technology to explore space, not uncovering a preexisting place or phenomenon. The invention of the telephone and the printing press are creations of new devices and systems, not discoveries of something that already existed. So, this event serves as the clear example of discovery.
