Translation:The data itself is still available.
Data is plural, datum is the singular. Therefore, 'is available' should be 'are available', and that also makes 'itself' wrong....but themself or themselves sounds wierd. Probably in english we wouldn't say itself or themself at all in this case.
Yeah, I know it's commonly used this way, so I have no problem with Duolingo accepting it used that way, I just think the 'correct' way should also be accepted!! I always have problems with weird...
But this can't be the dates are still available? dates is listed in the hover dictionary
Agreed. It makes sense if you're talking about booking a venue or something.
