Comparing them
- Sole trader/partnership: simple and private, but risky (unlimited liability), hard to raise finance.
- Companies: can raise more finance and protect owners, but face more rules and shared control.
Unlimited liability puts personal assets at risk. If a sole trader's business fails, creditors 债权人 can take the owner's personal possessions. A shareholder in a limited company cannot lose more than they invested.

Write from a personal claim of 5000
- A sole trader put 4000 into a business that now owes 9000.
- A shareholder who paid 4000 for shares can lose at most that 4000.
A sole trader invested 4000, and the failed business owes 9000. How much of the owner's personal wealth is still at risk, and how does that differ for a shareholder who paid 4000?
Unlimited liability reaches the owner's personal assets. Limited liability stops the loss at the amount invested in the shares.
How much beyond the 4000 already invested can creditors claim from the sole trader?

9000 minus 4000 is 5000, and unlimited liability leaves that amount at risk. Other options — Nothing (because every owner has limited liability); Only 4000 (the same cap as a shareholder).
