I want to know the answer to the following question:
In 2012 Fortune ranked the largest US firms by number employees, what was IBMs rank?
All the background I'm provided with is that "In 2012, Fortune ranked IBM the second largest U.S. firm in terms of number of employees (435,000 worldwide), the fourth largest in terms of market capitalization, the ninth most profitable, and the nineteenth largest firm in terms of revenue.". Is that enough to answer the question?
