A scientist is using relative dating to determine the age of a fossil that she discovered.What would allow her to draw the best conclusions about fossils that are younger than the one she discovered?

Relative dating compares the positions of rock layers rather than measuring exact ages. In undisturbed layers, those closer to the surface are generally younger than layers below them, so fossils found there would be younger than the discovered fossil. Therefore, finding fossils in layers closer to the surface gives the best evidence.
