"I love this man, even though he does not know how to sing."
Translation:Rakastan tätä miestä, vaikka hän ei osaa laulaa.
Just throwing my voice into the mix about the pronoun inconsistencies (sometimes one is penalized for inserting an allowed pronoun, other times for omitting it when unnecessary). I do not know whether the course design system requires the volunteers to explicitly enumerate the allowed answers--I can understand this might become a tricky sort of combinatorics issue at times, especially with more complex sentences. However the situation certainly is frustrating for the user, and it appears these issues have been present for at least 7 months.
