Problem: Text: Miniature pig (also micro-pig, teacup pig, etc.) is an erroneous term that is used to refer to small breeds of domestic pig, such as Pot-bellied pigs, Gottingen minipigs, Juliana pigs, Choctaw Hogs, or Kunekune (and specimens derived by cross-breeding with these). Notable features of most miniature pigs distinguishing them from other pigs may be defined by their possession of small, perked-back ears, a potbelly, sway back, chubby figure, rounded head, short snout, legs, and neck, and a short tail with thick hair at the end. Typically, most breeds of mini pigs will range from the minimum weight of 50 pounds (23 kg) to 200 pounds (91 kg).

Question: is there any such thing as a mini pig?
A: yes

Problem: Text: Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100,000 Hz. Elephants can hear sounds at 14--16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).

Question: do all animals hear the same frequencies of sound as humans do?
A: no

Problem: Text: The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas--killer whales are only absent from the Baltic and Black seas, and some areas of the Arctic Ocean.

Question: are killer whales and orcas the same thing?
A:
yes
