Re: the use of pronoun 'one'
"One" means "any person."
In informal writing, it's common to use "you" there, but it's an impersonal "you" and doesn't mean "you, the reader" but just "a person."
Its advantage is that it avoids the passive.
Instead of saying "It if were found that" you* can say "If one finds."
*Note that I just used "you" there. It could have been "one" instead.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
