My Wiki is Bigger than Yours: Part 2

The first version of this quiz was a hit, so we're bringing it back. Below are ten pairs; it's up to you to figure out which wikipedia article has the larger word count. Word counts don't include links, invitations to edit the article, references or photo captions. And, of course, no editing the articles to boost your scores.
