Former boyscout, been in several wilderness survival scenarios and I've got a few gripes that are absolutely driving me crazy.
1) Number eighteen. Climb a tree? Seriously? I'm guessing this answer sounded the best in the realm of speculation, but any survival manual that advocates this would be pulled. By climbing a tree, you're exponentially increasing your chances of serious injury, and you're wasting energy you would be relying on while waiting for rescue. Starting a fire was the answer I went with initially, because it is correct, as a plume of smoke is about as good a signal you'll be able to give off without a flare gun on hand. Get a fire burning hot enough, throw some green vegetation on there, and at the very least, someone will be sent out to investigate a potential wildfire. As noted in the explanation for the "correct" answer, the number one objective is to stay put and be rescued, and this is how it's done.
Furthermore, there's a couple of other problems: most forests consist of trees that are pretty uniform in height, so good luck seeing anything but more treetops. Secondly, the higher up you go on a tree, the thinner and weaker the limbs become. There is no real way to get to the very top where you'd need to be, and the higher you go, the better your chances become of un-surviving due to a deceptively fragile limb... which is kinda the opposite of what you're trying to accomplish. And lastly, assuming you made it to the very top, saw a distant landmark, and climbed back down safely, a visual approximation is not going to do you very much good, as humans are not natural orienteers. We have compasses because we're generally very bad at traveling in a straight line without guidance, and every human being has a tendency to constantly turn to either direction as they travel; given a long enough required travel distance, this can lead to lead to them missing the mark by miles, and having no idea which direction their target is from where they stop and reassess the situation, making the whole thing an exercise in unnecessary (and highly penalizing) exhaustion. This is why you need somebody else to come out and get your stranded ass in the first place, otherwise people wouldn't get lost.
2) A child does not stand a better chance of surviving in the woods than a soldier. I don't know if you've ever seen the Army's official wilderness survival guide, but there are things in there that children need to know, but won't, whereas a soldier will. How to find food, how to identify poisonous plants, how to build a shelter, how to maintain one's own health and perform necessary first aid, all those things. It's a romantic notion that children would be more in touch with nature since they're an empty glass, but I'd happily wager that a soldier would be the one to come out of that situation without his flesh transformed into buzzard droppings. I don't know about you, but I hear a lot of stories in the news about kids running away from home and being found dead due to exposure.
3) The purest and most readily available source of water is condensation, which could be captured using a dew trap. Your urinary tract is used in purging your body of toxins and chemicals; you can drink it, but it will hurt your health. You'll have more water drinking your own piss, sure, but you can survive on condensation without ingesting the crap your body decided to throw out with the bath water, so to speak. Running water from a stream would also be preferable if boiled and/or (if possible), strained through multiple layers of cloth (such as bandanas or clothing).
4) As was mentioned by someone else, a tent is an all-in-one elemental guardian. Modern tents (the only kind anyone is likely to have on hand anymore) are basically tarps stretched over metal skeletons, and they not only provide cover from insects, rain, wind, and having your heat leeched by the ground, but they're also very effective at containing heat would've escaped through natural radiation from the body.
Everything else was on the money, but those four really drove me nuts. Especially the first.
Note: I'm not trying to be anal or a know-it-all, but someone, at some point, could be in this very situation and may rely on what this quiz informed them was the correct thing to do; much in the way I imagine a little girl could cost herself a limb by putting a tourniquet on an appendage with a minor laceration because she read about it in Twilight, the would-be survivor could end up being their own worst enemy.
