Scenario: Cleaner shrimp is the name given to shrimp that clean other organisms of parasites, which are tiny harmful animals. These shrimp live on coral reefs throughout the oceans. Cleaner shrimp hang out in sections of the coral reef and wait for fish to approach to be cleaned, similar to a car wash station. With no hesitation or fear of being eaten, the cleaner shrimp enters the mouth of the larger fish and vacuums up parasites and dead
cells. Cleaner shrimp go wherever they want, even through the delicate gills of larger fish, to pry out the parasites. The larger fish get cleaned, sanitized, and groomed, and become healthier from this service. The cleaner shrimp get fed.

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. c. most of the societies that collapsed during droughts did so when internal power struggles coincided with military raids from neighboring societies. d. most of the societies that collapsed during droughts maintained large stockpiles of food and water at the time of their collapse. e. information from stalactites also suggests that the collapse of some societies coincided with periods of abnormally high rainfall.
