Q1 Which of the following is a correct statement about implementation of subprograms? Deep access method is faster in accessing the references to distant nonlocals than shallow access. Shallow access method is costly in accessing the references to distant nonlocals than deep access. In deep access method, the activation record instances on the dynamic chain are used for accessing nonlocal references. In the shallow access method, variables declared in subprograms are stored in the activation records of the subprograms for access. Subprogram linkage is more costly for deep access than shallow access method in dynamic scoping. Q2 What determines whether a method definition in a derived class or an ancestor class will be used? the return type of the method the type of the variable that names the object the object's place in the inheritance chain the derived class's descendants none of the above
