Trawf, the manager of a state fair, contracted 100. with Schweinebauch, a renowned hog breeder, to exhibit Schweinebauch's world champion animal, Megahawg, for the three weeks of the annual fair, at the conclusion of which Schweinebauch would receive an honorarium of $300. Two days before the opening of the fair, Megahawg took sick with boarsitis, a communicable disease among swine, and, under the applicable state quarantine law, very probably could not be exhibited for at least a month. Upon learning this, Trawf can legally pursue which of the following courses of action with respect to his contract with Schweinebauch? 
Suspend his own performance, demand assurances from Schweinebauch, and treat a failure by Schweinebauch to give them as an actionable repudiation.  Suspend his own performance and recover damages from Schweinebauch for breach of contract unless Schweinebauch at once supplies an undiseased hog of exhibition quality as a substitute for Megahawg. Terminate his own performance and treat Megahawg's illness as discharging all remaining duties under the contract. Terminate the contract, but only if he (Trawf) seeks promptly to obtain for the exhibit a suitable substitute for Megahawg from another hog owner.
