1. The problem asks to identify the error in Jacy's conditional statement and provide the correct conditional. 2. The original statement is: "Water freezes if it is below 0°C." 3. This means: If the temperature is below 0°C, then water freezes. 4. Jacy wrote: "If water freezes, then it is below 0°C." 5. This reverses the hypothesis and conclusion. The hypothesis (condition) should be "temperature below 0°C," and the conclusion should be "water freezes." 6. The correct conditional is: "If water is below 0°C, then it freezes." 7. Therefore, the error is reversing the hypothesis and conclusion. Final answer: A. She reversed the hypothesis and the conclusion. The correct conditional is "If water is below 0°C, then it freezes."
