Consider the following class interfaces: class Teacher
{
public:
Teacher();
Teacher(string new_name);
string get_name() const;
private:
string name;
};
class MathsTeacher : public Teacher
{
public:
MathsTeacher();
MathsTeacher(string new_qualification, string new_name);
void display_data() const;
private:
string qualification;
};
int main()
{
Teacher t1, t2("John");
MathsTeacher mt1, mt2("TopLevel", "Sarah");
t1 = mt1;
t1 = t2;
mt1 = mc2;
mt1 = t1;
return 0;
}

Which one of the preceding assignment statements in the function main() would slice away the data of the derived class object?
A. c1 = ac1
B. c1 = c2
C. ac1 = ac2
D. ac1 = c1

The technology acceptance model (tam) is a two-factor model that describes user acceptance of new or replacement technology solutions (davis, 1989). this evaluation model has withstood the test of time and is widely used. the model is based upon perceptions and beliefs of individuals and measures two types of factors: (a) perceived ease of use and (b) perceived usefulness. prepare an analysis (briefing paper) (5 to 7 strong paragraphs) in which you explain how cybersecurity researchers could use the tam model to explore the factors which affect employee acceptance of biometrics used for access to facilities and/or computing systems. what research questions might they ask? what measurements would be needed? post your briefing paper as a reply to this topic. remember to cite your sources (3 minimum) and include a reference list at the end of your posting.
