Transitions Practice Test

Which choice completes the text with the most logical transition?

Historians of public health note that early anti-tuberculosis campaigns emphasized fresh air and sunlight, partly because antibiotics did not yet exist and partly because sanatorium regimens were one of the few interventions that seemed to help some patients. _______ these campaigns also produced detailed municipal records—on housing density, workplace ventilation, and neighborhood mortality—that later researchers used to map how poverty and urban design shaped disease outcomes.​​

Which choice completes the text with the most logical transition?

Marine ecologists once assumed that restoring a single “keystone” predator would automatically rebuild an entire coastal food web, because that predator’s hunting pressure can suppress mid-level consumers that otherwise overgraze algae and seagrass. _______ long-term monitoring of several reintroduction sites shows that when shoreline development has already reduced nursery habitat, the predator’s return produces only modest changes in vegetation and fish diversity, suggesting that top-down control depends on intact physical conditions as well.​​
