Questions: Question 4 1 pts As grapes ripen: The acidity level and the sugar level both drop The acidity level and the sugar level both increase The acidity level increases and the sugar level drops The acidity level drops and the sugar level increases

The answer is the last one: The acidity level drops and the sugar level increases.

Explanation for each option:

1. The acidity level and the sugar level both drop: This is incorrect. As grapes ripen, the sugar content typically increases due to the conversion of starches into sugars.

2. The acidity level and the sugar level both increase: This is incorrect. While the sugar level increases, the acidity level actually decreases as the grapes ripen.

3. The acidity level increases and the sugar level drops: This is incorrect. The opposite occurs; the acidity level decreases and the sugar level increases.

4. The acidity level drops and the sugar level increases: This is correct. As grapes ripen, the natural acids in the grapes decrease, leading to a drop in acidity, while the sugar content increases, making the grapes sweeter.

In summary, as grapes ripen, the acidity level drops and the sugar level increases.
