1. Jane is cooking soup now.
To make a positive sentence from the given negative sentence, we simply remove the word "not" and keep the rest of the sentence unchanged. So, the correct positive sentence would be "Jane is cooking soup now."

2. The children are brushing their teeth.
Similarly, to form a positive sentence, we remove the word "not" and keep the rest of the sentence unchanged. Therefore, the correct positive sentence is "The children are brushing their teeth."

3. She is flying to Venice today.
Again, we remove the word "not" and keep the rest of the sentence unchanged to form a positive sentence. Hence, the correct positive sentence is "She is flying to Venice today."

Remember, when we are changing negative sentences to positive, we simply remove the word "not." It is important to pay attention to the tense and subject of the sentence to maintain accuracy.
