"How are you Rohan?" Dr. Bailly asked Rohan Jamtgaard, speller 102 and a Colorado eighth grader.
"I'm... tired, but OK," Rohan said.
"Yeah. It's a long day today," Dr. Bailly concurred.
Rohan misspelled "effluent," something that flows out, such as liquid discharged as waste (as water used in an industrial process).
