1. B
Explanation: The Rhone Valley acts as a wind tunnel, narrowing between the Alps and Massif Central, accelerating the wind through topographic funneling.
2. C
Explanation: The Mistral dries the environment, reducing fungal infections in crops like grapes and olives, aiding agriculture rather than harming it.
3. C
Explanation: The Mistral results from a high-pressure system over Atlantic/Northern France and a low-pressure system over the Mediterranean.
4. B
Explanation: It is a cold, dry wind due to its northern origin and adiabatic cooling from descending through the valley.
5. C
Explanation: While all are local winds, Harmattan (dry wind from Sahara towards West Africa) differs in continent, mechanism, and temperature compared to the Mistral.
