Text: The common hippopotamus (Hippopotamus amphibius), or hippo, is a large, mostly herbivorous, semiaquatic mammal native to sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). The name comes from the ancient Greek for ''river horse'' (). After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, dolphins, porpoises, etc.) from which they diverged about 55 million years ago.

Text: For example, if the stock price for two companies is $25 per share and one company has a cash flow of $5 per share (25/5=5) and the other company has a cash flow of $10 per share (25/10=2.5), then if all else is equal, the company with the higher cash flow (lower ratio, P/CF=2.5) has the better value.

Question: is a high price to cash flow ratio good?

Text: Faster-than-light (also superluminal or FTL) communication and travel refer to the propagation of information or matter faster than the speed of light. The special theory of relativity implies that only particles with zero rest mass may travel at the speed of light. Tachyons, particles whose speed exceeds that of light, have been hypothesized but the existence of such particles would violate causality and the consensus of physicists is that such particles cannot exist.

Question: can anything be faster than the speed of light?

OPTIONS:
- no
- yes

Text: This myth was tested on the Discovery Channel program MythBusters, and subsequently debunked. Mythbusters' co-host Adam Savage was already quite familiar with the throwing card trick and was shown to be quite adept at performing it, with his maximum throwing speed being clocked at 25 miles per hour or 40 km/h. The episode also featured Ricky Jay himself, who spoke of writing the book and admitted he is most likely responsible for the genesis of the myth. The hosts were able to clock the speed of his throws at about 90 mph. After failing to throw the cards into a ballistic gelatin target with enough force that would result in injury, they used an electric motor to mechanically launch a card at 150 mph. Offering his own body as a target, host Jamie Hyneman allowed the launcher to be fired at his exposed skin from a few feet away, which only resulted in a superficial paper cut. The hosts concluded that a playing card lacks enough mass to transfer sufficient energy to human tissue on impact.
