Well, for once we were right: this week’s Challenge ( Challenge 3 ) is a little harder than the first two Challenges . (In fact, we’ve even gotten a couple of emails that said, "This week’s Challenge is harder than the first two.") But don’t panic. If you haven’t been able to come up with the answer to this week’s Challenge, well, here’s a hint for you:
Football (at least American football) is this kind of sport.
Sorry, that’s the only hint you’re going to get from us. If that’s not good enough, then we have just one thing to say to you: lenses. And what do we mean by that ? Sorry, that’s the only hint you’re going to get from us.
