I want to know the answer to the following question:
How many gallons of liquid cleaning agent leaked from an IBM facility in 1979?
All the background I'm provided with is that "IBM used liquid cleaning agents in circuit board assembly operation for more than two decades, and six spills and leaks were recorded, including one leak in 1979 of 4,100 gallons from an underground tank.". Is that enough to answer the question?
Answer: yes
