Question 3 options: a) yes, because even though this transaction appears to be a "sale in gross," the deficiency of almost 30% would be found too excessive by most courts. b) no, because this transaction appears to be a "sale-in-gross," and a 30% deficiency would not be found sufficient to rescind the contract by most courts. c) no, because classifying this transaction as a "sale-in-gross" as opposed to "sale per acre" has no bearing on the result.
