Option D is the correct answer as the language spoken by characters is not connected to the time, environment or location of a story. Hence option D is not an element of the setting.

John Rawls (b. 1921, d. 2002) was an American political philosopher in the liberal tradition. His theory of justice as fairness describes a society of free citizens holding equal basic rights and cooperating within an egalitarian economic system.

Equality has three Basic elements: Absence of special privileges in society. Presence of adequate and equal opportunities for development of all. Equal satisfaction of basic needs of all.

The element-of symbol is used in mathematical set theory to indicate that a point, object, or number belongs to a certain set. The symbol resembles the lowercase Greek letter epsilon, but stretched out ( ). It is read “is not an element of,” “is not a member of,” “is not in,” or “does not belong to.”

The elements of set are written inside a pair of curly braces separated by commas. (vii) The symbol ‘∉’ stands for ‘does not belongs to’ also for ‘is not an element of’. Therefore, x ∉ A will read as ‘x does not belongs to set A’ or ‘x is not an element of the set A’.

The set of integers is represented by the letter Z. Integers are sometimes split into 3 subsets, Z+, Z- and 0. Z+ is the set of all positive integers (1, 2, 3.), while Z- is the set of all negative integers (…, -3, -2, -1). Zero is not included in either of these sets .

There is actually rather a lot of debate within the math community about the inclusion of zero as a natural number. However, the IB Studies curriculum considers 0 to be a natural number.
