Switching from chains to cables in the building of roller coasters was important because cables are less likely to snap when hauling several tons of roller coaster cars full of people. Chains are made of linked, welded pieces of metal that can easily snap if they pull too much. Cables, while they can snap, are much less likely to do so, because they're a stretch of fibers, be it metal or other, without any potential weak spots.
Humanity's early fire-starting tools may have been dangerous because in the text is says,<span> "It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions." This is dangerous because it would spew fire in all directions and if you think about it, the fire would hit something and then that thing would catch on fire. Lets say you were using the match inside your house. When you strike the match, a spark flies onto the wood floor and your house goes up in flames and you are stuck inside the house with no exit or escape. This may or may not happen, but because of the fire not being contained, there was a chance that you would be harmed.</span>

First we must find the number of bags that hold 5/6 pound and that number multiplied by 5/6 must be a whole number. For example: 5/6 * 6 = 5. Also that number must be divisible by 2 ( because we have 2 pound bags of peanuts to replace ). Therefore: 5/6 * 12 = 10 pounds.
10 : 2 = 5 bags.
