I have a problem that needs to be solved and I don't even get what the question is talking about. Please help me explain and solve this problem. Thanks very much.

Question: A transfers $100 in uncollected customer accounts receivable (from A's cashbasis service business) to X in exchange for half of X's common stock plus X's assumption of $50 of accounts payable attributable to the service business (which $50 A could have deducted upon payment in cash). B transfers $50 in cash to X in exchange for the other half of X's stock. X uses this cash to pay off the assumed accounts payable. Variation: A transfers the receivables but not the payables to X (and vice versa).

For this problem, I need to determine the following:

1. A's amount realized
2. A's gain or loss realized
3. A's gain or loss recognized and the character thereof
4. A's basis in the X stock received
5. A's holding period for the X stock received (tacked or not?)
6. X's basis in the property received
7. X's holding period for the property received (tacked or not?)
8. The amount and character or X's gain if X immediately sells the property for $100
