Assertion and Reason
Directions: The following question has two statements, Assertion and Reason.
Answer the question by choosing any one of the four responses.
Assertion: Brain and spinal cord are called modulators.
Reason: Their neurons receive a stimulus and set up a sensory impulse.
If both Assertion and Reason are true and Reason is the correct explanation of Assertion
If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
If Assertion is true but Reason is false
If Assertion is false but Reason is true
