Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The average human produces approximately 1-2 liters of saliva per day. Over an 80-year lifetime, this equals about 25,000-35,000 gallons. The claim of 100 gallons is dramatically understated by a factor of hundreds. This makes the False answer correct for the wrong quantitative reason.
