I want to know the answer to the following question:
The shadow banking system could not provide funds to mortgage firms and other corporations without the ability to obtain which funds?
All the background I'm provided with is that "Without the ability to obtain investor funds in exchange for most types of mortgage-backed securities or asset-backed commercial paper, investment banks and other entities in the shadow banking system could not provide funds to mortgage firms and other corporations.". Is that enough to answer the question?
Answer: yes
