Scientist: Cross-sections of stalactites - calcite formations deposited on cave ceilings by seeping water - can reveal annual variations in rainfall in particular areas over hundreds and thousands of years. We often found that when - according to these cross-sections - drought occurred in a particular area, it coincided with the collapse of an ancient society in that area. I hypothesize that drought reduced agricultural productivity in these areas, thereby leaving these societies without the resources needed to handle internal stresses and external threats.
Which of the following, if true, would most weaken the support for the scientist's hypothesis?
A. Many droughts indicated in the cross-sections of stalactites do not correspond with the collapse of a society in that area.
B. Information from the cross-sections of stalactites alone cannot reveal the level of agricultural output in an area at a particular time.
