by combining knowledge from past reports with new information by providing information collected by other meteorologists by checking the accuracy of each part of the weather report by showing many components that impact the weather
I gave my students this multiple choice question: Some meteorologists use visual aids such as diagrams, maps, and charts when they present the weather to television viewers. How do different types of visual aids help the viewers understand complex weather phenomena?

Only one answer is correct among these 4 choices:
- by combining knowledge from past reports with new information
- by providing information collected by other meteorologists
- by checking the accuracy of each part of the weather report
- by showing many components that impact the weather

Could you tell me which one is correct?

by showing many components that impact the weather
