Inheritance d. the 'is a' relationshipExplanation / Answer
1) python - object oriented languaage without variable declarations and using white space for seperation
2) extends - word used in java to create a subclass
3) garbage - data with no path to it
4) cobol - language used for business; contains decimal number primitives
5) scheme - dialect of lisp often used in AI
6) fortran - qualites or properties of a variable
7) cast - explicit change of type by the programmer
8) lexeme - smallest unit of a language
9) dangling reference - a path that points to nothing useful
10) coercion - automatic change of data type by the compiler
11) table - group of information in a database, with rown and columns.
12)
inheritance allows a new class to inherit members of the class it extends
13)
