Answer:
Randomized
Explanation:
Observational Studies and Randomized Trials are two ideal ways of determining the outcome of certain tests.
In the Observational course the study is conducted in a true to life scenario and the result of what happens is recorded. Meanwhile, in the Randomized Trial there purposefully placed conditions that are ideal and these are evaluated after specific interventions.
Since the pool manager did not let different pools grow algae at will before putting in the chemical this study would not be considered observational. Instead he set up three different pools of the same size with the similar amount of contaminants and then tested the algaecide. This classifies this as a Randomized Trial.

The world’s smallest population of mountain gorillas—a subspecies of the eastern gorilla—is split in two and scientists have debated whether they may be two separate subspecies. A bit more than half live in the Virunga Mountains, a range of extinct volcanoes that border the Democratic Republic of Congo, Rwanda and Uganda. The remainder can be found in the Bwindi Impenetrable National Park in Uganda. Since the discovery of the mountain gorilla subspecies in 1902, its population has endured years of war, hunting, habitat destruction and disease—threats so severe that it was once thought the species might be extinct by the end of the twentieth century.
