The test variable (independent variable) and outcome variable (dependent variable) have no affect on each other.

B.
The test variable (independent variable) controls the outcome variable (dependent variable).

C.
The outcome variable (dependent variable) controls the test variable (independent variable).

D.

the answer is kevlar

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic

a self-report inventory personality assessment is not very reliable for a psychological test because a patient doing the assessment may exaggerate or under-report in the answers. also, people will tend to be high on desirable behaviors and low on undesirable things.
