Explanation:

The text states "Sometimes wind is gentle... Other times wind is dangerous". This shows that wind is not always dangerous but has times when it is. Option C "sometimes" matches this description. Option A "not" is incorrect as the text clearly says wind can be dangerous. Option B "always" is wrong because there are times (like when it's a gentle summer breeze) it's not. Option D "never" is also incorrect as the text mentions hurricane - related dangerous wind.
