These studies, however,failed to link unequivocally terrestrial climate and the solar activity cycle, or even to confirm the cycle s past existence.

　　13. It can be inferred from the passage that studies attempting to use tree-ring thickness to locate possible links between solar periodicity and terrestrial climate are based on which of the following assumptions?

　　The solar-activity cycle existed in its present form during the time period in which the tree rings grew.

　　The biological mechanisms causing tree growth are unaffected by short-term weather pat terns.

　　Average tree-ring thickness varies from species to species.

　　Tree-ring thicknesses reflect changes in terrestrial climate.

　　Both terrestrial climate and the solar-activity cycle randomly affect tree-ring thickness.
