Which report gives basic observer data?

• A. Report Four
• B. Report Two
• C. Report One
• D. Report Five

Answer: (C)

The main idea here is distinguishing types of data in reports: basic observer data is qualitative and descriptive, coming from someone who witnessed the event with no instrumentation or measurements added.

The best choice is the report that sticks to simple, descriptive observations from an on-scene observer—things like what was seen, heard, or smelled, written in plain language and without numbers or instrument readings. This kind of report provides the initial, unprocessed account of the event.

Other reports typically include instrument readings, measurements, time stamps, graphs, or calculations. Those go beyond basic observer data, so they wouldn’t be classified as the simplest observer account.
