Our prediction is that we produce saliva by drinking water. We think this is a sensible prediction because we have used our background knowledge and thinking to get this prediction.
Answer
We couldn’t find much information on how we produce saliva. But the most solid info we found was that we produce saliva by drinking water. This we think is true because when we feel thirsty or short of saliva we just drink water and we feel like there’s water in our mouths. We also read in a paragraph that 98% of our saliva is water so there you go.
