Which of the following is/are not correctly matched?

1. Savannah Climate - Tall grasses
2. Mediterranean Climate - Prominence of local winds
3. Equatorial Climate - Double rainfall peaks coinciding with the equinoxes
4. Steppe Climate - Extensive mechanized wheat cultivation

Savannah Climate - The landscape is typified by tall grasses (6-12 feet high) and short trees. The grass appears greenish and well-nourished in the rainy season but turns yellow and dies down in the dry season that follows. The grass lies dormant throughout the long, rainless period and springs up again in the next rainy season. Mediterranean Climate - Prominence of local winds (some hot and others cold); the passing cyclones from the Atlantic, the anticyclones from the north and the cold air masses from the continental interiors are often interrupted or channeled by relief features resulting in the birth of local winds (such as Sirroco, Mistral) around the Mediterranean. Equatorial Climate - There are two periods of maximum rainfall, in April and in October, which occur shortly after the equinoxes. Therefore, double rainfall peaks coinciding with the equinoxes are a characteristic feature of equatorial climate not found in any other type of climate. Steppe Climate - Extensive mechanized wheat cultivation (All of them are correctly matched. So, option '4' is the correct answer.)
