Animal Test

I was given this little quiz in year 5. I thought it was a cheap trick of illogic then and I think it's a cheap trick of illogic now.
How do you build a bridge spanning 200 metres?
By stacking wood together, my good sir; any thought to physics and engineering practices is an overly complicated solution.
If only someone would tell those structural engineers.

Person 2. He can see the hat ahead of him. He has to assume his hat is not that same color. If it were, then the man at the back of the row would have spoken up about what color his own hat was. Person 1 would have seen Person 2 and 3 with the same color, and known his was difference. His silence tells person 2 all he needs to know to get it right.

This though assumes that once the person who deduces it is them must say that it is them. Person 1 might know (although he won't because the people in front of him have different coloured hats but Person 2 doesn't know this if he doesn't have to say either way) but he might not say even if he did know.

Yep, the only assumption I made was that the person who did manage to deduce it would then announce that they figured it out. The absence of that declaration is what allows the riddle to be solved. No idea if I'm right though. The guy who posted the question hasn't responded to the thread.

Back now...

And yes, Landslide, you're right.

Next time I'll have to add a clause that one has to call out when he figures it out. Or rather state a reward of some kind to make people call out when they get it.
