问题     One interpretation regarding the absence of fossils during this important 100-million-year period is that early animals were soft bodied and simply did not fossilize.Fossilization of soft-bodied animals is less likely than fossilization of hard-bodied animals, but it does occur.Conditions that promote fossilization of soft-bodied animals include very rapid covering by sediments that create an environment that discourages decomposition.In fact, fossil beds containing soft-bodied animals have been known for many years.
Look at the four squares[]that indicate where the following sentence can be added to the passage.
It is relatively rare because the fossilization of soft-bodied animals requires a special environment.
Where would the sentence best fit?
