Hey,
please look at the IR question posted here:
https://www.beatthegmat.com/graphics-in ... 09048.html
According to the solution in GMATPrep, the _beginning_ of the Cambrian Period marks the onset of a new era, eon and period.
While it is obvious that it marks the onset of a new period, it isn't clear to me why it should also mark the onset of a new eon and era. According to the provided graphic, its _end_ marks the onset of a new era and eon, but its beginning still lies within another era and eon.
Any thoughts?
Thank you,
Kevin
