Eyewitness observations about the Earth (letters, diaries, speeches, and interviews) are an example of which type of source?

• A. Eyewitness Observations
• B. Maps
• C. Primary Sources
• D. Aerial Photographs

Answer: (C)

Eyewitness observations are original, first-hand records created by someone who experienced the event. Letters, diaries, speeches, and interviews capture what the observer saw or heard at the time, making them primary sources. They provide direct evidence of historical events and firsthand perspectives, unlike secondary sources that summarize or analyze after the fact. While maps or aerial photographs can also be primary sources if produced at the time, the given examples clearly exemplify direct accounts from witnesses, which is why this is the best fit.
