Answer:
Lack of funds and management.
Explanation:
We are asked to determine the the major causes of small-business failure.
We know that lack of funds or money is main cause of small business failure. In the startup phase small companies face challenges in obtaining funds to bring a new product to market.
The second cause is the lack of management. A strong management team is must for a successful business.
It is possible that these causes will apply to larger businesses, but not always a must. Since large businesses have more money to support them, so these causes are less applied to larger businesses.
