The statement that best describes a major difference in the quality of weather information contained in a daily forecast and a long-range forecast is:
"Information contained in a daily forecast is more accurate than the information included in a long-range forecast."
Daily forecasts are based on more immediate data and can provide a higher level of detail and accuracy for short-term weather events, whereas long-range forecasts tend to be less precise and more generalized due to the inherent uncertainties in predicting weather far in advance.
