Answer: Extraordinary assumption
Explanation: Appraisal could be defined as the estimation or evaluation of an object, property or structure in other to determine either the worth, condition or nature of such property or object.
An Extraordinary assumption during appraisal means a presumption that certain unknown information exists or is a fact. It assumes a condition which is unknown to be true and as such if the information is found to be false may alter the result or conclusion of the appraisal.
Such is the scenario above, when the appariser assumes there is no leakage or contamination based merely on unknown fact.

Mr. Dolphus Raymond is known as the town drunk, because he always carries his drink in a brown paper bag, and tends to sway a bit in his walk. Mr. Raymond is also married to a black woman and has mixed children. When running from the courthouse, Dill and Scout run into Mr. Raymond and he offers Dill a sip of his drink. Scout is wary, but Mr. Raymond promises Dill it will make him feel better. Dill takes a sip and discovers Mr. Raymond is hiding a bottle of Coca-Cola in his infamous paper bag. Scout asks why he does such a thing, and Mr. Raymond explains he feels he has to give the population some reason for his odd behavior (being friendly toward black people). Mr. Raymond believes it's easier for people to handle strangeness when they have a reason to explain it. Thus, he pretends to be a drunkard.
