Litigation is the correct answer. This is not a way in which a contract can end- it is a conflict resolution method. The three ways in which a contract can end are; performance, agreement and breach. See p. 42 for more details on how contracts end

"No- there has been a breach in warranty" is the correct answer. The key to answering this question lies in the fact that the specification in this example is a warranty rather than a condition of the contract. P.45 of the study guide explains that the Sale of Goods Act has implications on whether or not a specification is a condition, warranty or innominate term and it's all about whether the product is in 'good condition' and can be used for its intended purpose. In this example the eggs were used for their intended purpose and were in good condition (or Sarah wouldn't have put them in the cakes). Therefore in this example, the eggs needing to be free-range is a warranty of the contract not a condition. Therefore options A and B are both wrong. Answer C is also wrong because the question mentioned that the specification was included in the contract. If you want to know more about the implication of the Sale of Goods act on specifications see p.45.

"no- the contract can be affirmed by the injured party" is the correct answer. When there is a breach in a condition, one of two things can happen; the contract is terminated, or the contract is affirmed. The injured party has the choice of whether or not they want to continue working with the other party and this is called 'affirmirmation of the contract'. The contract doesn't HAVE to be terminated in the case of a major breach so options 1 and 2 are incorrect. Option 4 is also incorrect- the contract can continue even if the offending party says they'll commit further breaches - it's completely up to the injured party whether they want to continue working with them or not. See p. 46 for further details

The correct answers are as follows:

This is adjudication. Adjudication is the only option which has a specified timeframe.

Exporters prefer advance payment - this puts the risk with the importer / buyer. There's a table of these four terms on p.36. An importer would prefer an open account arrangements. The other two options are in the middle and the risk is more equally split between the two parties.
