An epoch is longer than an era.
This question is asking for the number of ATP that is produced by the citric acid cycle and the electron transport chain.
Citrate is the first biological substance in the citric acid cycle and it is the starting point of the cycle. From one molecule of citrate, the citric acid cycle will produce 2 ATP while the electron transport chain will produce 34 ATP. Therefore, together both the citric acid cycle and the electron transport chain will produce 36 ATP.
