Translation:The foot is swelling
the english is missing a space, but it says "the foot" has an extra space. Whoops.
10-MAY-2018: Reported that "Thefoot is swelling" is an unnatural or erroneous answer.
I can't report that my answer should be correct, but the space should be here. Wasn't counted wrong, because it looked at it as a typo. Some of the comments in this course are more than a year old. Is someone still working on this course?
I don't think older comments are ever removed. The course developers don't have time to read them, so we have to actually hit 'Report' if we want to get their attention. They are only volunteers and I get the impression that they check the reports in bursts when they find time. Unfortunately, it's a slow process.
Update (11 Jan 2019): The course developers have been impressively busy in the last month or so. I have had countless reports accepted. Things are definitely looking up!
