Answer: Considering the six criteria that made up an enforceable contract:
(I) Offer and acceptance: There's no clear acceptance between Peter and BIG, because the peter responded with "Most likely", which implies that peter might later decline BIG's offer
(Ii) Mutual agreement : Peter response shows that he didn't understand the terms and conditions that made up the contract, so, there was no agreement between the too.
(Iii) Consideration wasn't been met
(Iv) competent parties: Both parties we're unable to understand the contract, so, they weren't competent
(V) legality of purpose: this also was not met, since there was no clear acceptance
(Vi) proper form: Peter response seems ambiguous, therefore, the contract wasn't enforceable
