What is the result.
Agree. I have reported it
how were the results...?
Agree. That's what I wrote, too, but it was counted as incorrect.
"How is the result" does not make sense. We would say "What is the result?" or we would say "How is the result measured." The work "How" is not a pronoun. The word "What" is a pronoun. The sentence needs a predicate noun (pronoun).
