The test compound and secondary compound cause the same response when 



administered alone (though at different intensities). 

 The test compound causes a response opposite to that caused by the secondary 



compound (Fig. 3) or the test compound's causing the same or the opposing 



response to the secondary compound is not known (Fig. 4). 

 The intensity of response to the test compound when administered alone is 



known. 

 The intensity of response to the test compound when administered alone is
