In a study on antelopes, which graph best represents the male-female predation risk trend?
Graph 4 is the keyed representation of the male-female predation-risk trend in the antelope study. Sex-specific risk can differ because body size, group position, vigilance, habitat use, reproductive condition, and movement affect predator detection and escape. A valid graph must represent the observed direction and relative magnitude for both sexes across the study's independent variable, rather than presuming that one sex is always safer. The workbook contains only graph numbers and does not embed the four candidate plots, so slopes and axes cannot be described reliably. The selection should
