问题     The challenge of predicting organismal responses to global climate change is difficult.Partly, this is due to the fact that there are more studies of short-term, individual organism responses than there are of long-term, systemwide studies.It is extremely difficult, both monetarily and physically, for scientists to conduct field studies at spatial and temporal scales that are large enough to include all the components of real-world systems, especially ecosystems with large, freely ranging organisms.One way paleobiologists try to get around this limitation is to attempt to reconstruct past climates by examining fossil life.
Look at the four squares[]that indicate where the following sentence can be added to the passage.
Much of this work depends on the assumption that life forms adapted to a particular climate in the present were adapted to the same type of climate in the past.
Where would the sentence best fit? [br]
