Answer: If Sheila had a reasonable belief that she was telling the truth, Jacobi can rescind the contract, but he cannot collect damages.
Explanation: From the given text it can be concluded that Sheila did not intend to deceive Jacobi, that is, she was telling the truth when she claimed that the sofas were in good condition, except that the only issue was that the fabric on the sofas was slightly worn. Because this is an unintentional mistake, that is, Sheila's claim that everything else with the sofas is okay, Jacobi can rescind the contract but cannot collect damages.
