Unable to extract downloaded dataset

[skurnool143]

I tried to extract dataset ("rc" version) which I downloaded from http://nlp.cs.washington.edu/triviaqa/ , for some reason the downloaded file is corrupted and it cannot be extracted.

Below is the log:

$ tar xf triviaqa-rc.tar.gz
tar: Skipping to next header
tar: Exiting with failure status due to previous errors

I even downloaded from web directly but still not able to extract the downloaded dataset.
is dataset hosted at http://nlp.cs.washington.edu/triviaqa/ valid now?
