Question 1124Navigation General

The correct answer is D) sea level. Barometer readings in weather reports are given in terms of the pressure at sea level. This is a standard practice in meteorology, as sea level is used as a reference point for measuring atmospheric pressure. The pressure at sea level is the most relevant and useful information for weather forecasting and reporting, as it provides a consistent baseline for comparison across different locations. The other answer choices are incorrect because they do not represent the standard reference point for barometer readings. Pressure at the weather station or broadcasting station would be less useful for weather reports, and pressure at Washington, D.C. would be an arbitrary and irrelevant location for this purpose.
