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 balloon rocketed into the sky. Though we were frightened, everything ended up being fine.
- The word "quickly" can be removed because speed is implied with the word "rocketed"
- The phrase "into the really cold air" can be removed because it is irrelevant to what's happening. It can be replaced by "into the sky"
- Now "up" can be removed because "into the sky" implies that the balloon went upwards.
- Either the word "scared" or "frightened" can be removed because they're synonyms (I chose to remove "scared")
- "Because it was moving really fast" can be removed because the use of the word "rocketed" beforehand already implies that the balloon was moving fast.
- Lastly , I just reworded and conjoined some of the sentences to make them read more clearly though this isn't necessary. (I changed the third sentence from "However, it was all good in the end," to "everything ended up being fine." I also combined the second and third sentences, adding "though" in front of the second sentence to make it a dependent clause)
While not as strikingly beautiful as Cherry, Marcia is small and cute with dark hair. Two-Bit normally goes for Greaser blondes, but he really hits it off with Marcia because they are so much alike. They both have the 'same scatterbrained sense of humor. Hopefully this helps a bit
I would say foreshadowing because it says “eventually” which means you’re saying like “fast forward to this event”. It hasn’t happened but your telling what did happen.
