Question: Rhinoceroses and horses are related. They have very similar digestive systems and an odd number of toes on their feet. Horses have one toe, and rhinoceroses have three. These facts best support which claim?
Answer: Horses and rhinoceroses share a common ancestor.
Hypothesis: rhinoceroses and horses might share a common ancestor
Supporting facts: sent1: in common is similar to the same sent2: horses are a kind of organism sent3: if two things perform the same function then those two things are similar sent4: a rhinoceros is a kind of animal sent5: rhinoceroses are a kind of organism sent6: three is more than two sent7: similar means in common sent8: a part of something means a characteristic of something sent9: if two objects are similar , then the two objects share properties sent10: where something comes from is a source of that something sent11: a structure of something is synonymous with a part of that something sent12: a horse weighs, usually between 400 and 550 kg sent13: if two or more organisms have similar characteristics then those organisms might share a common ancestor sent14: type of digestive system is a kind of characteristic sent15: if two species of animal have a similar bone structure then those two species probably evolved from a common ancestor in recent geological history sent16: similarity means the same property sent17: an odd number of toes is a property of rhinoceroses sent18: genetic / hereditary means of genes / heredity sent19: rhinoceroses and horses have similar digestive systems sent20: rhino means rhinoceroses sent21: an odd number of toes is a property of horses sent22: a horse is a kind of animal sent23: to digest means to break down food sent24: number of toes is a property of bone structure sent25: both means two
Reasoning: [BECAUSE] an odd number of toes is a property of rhinoceroses [AND] an odd number of toes is a property of horses [INFER] int1: horses and rhinoceroses both have an odd number of toes [BECAUSE] int1 [AND] number of toes is a property of bone structure [INFER] int2: rhinoceroses and horses have a similar bone structure [BECAUSE] a horse is a kind of animal [AND] a rhinoceros is a kind of animal [INFER] int3: a rhinoceros and a horse are kinds of animals [BECAUSE] int2 [AND] int3 [INFER] int4: rhinoceroses and horses are kinds of animals that have similar bone structures [BECAUSE] int4 [AND] if two species of animal have a similar bone structure then those two species probably evolved from a common ancestor in recent geological history [INFER] int5: the bone structure of rhinoceroses and horses indicate that they might have evolved from a common ancestor [BECAUSE] type of digestive system is a kind of characteristic [AND] rhinoceroses and horses have similar digestive systems [INFER] int6: rhinoceroses and horses have  similar characteristics [BECAUSE] horses are a kind of organism [AND] rhinoceroses are a kind of organism [INFER] int7: rhinoceroses and horses are kinds of organisms [BECAUSE] int6 [AND] int7 [INFER] int8: rhinoceroses and horses are kinds of organisms that have similar characteristics [BECAUSE] int8 [AND] if two or more organisms have similar characteristics then those organisms might share a common ancestor [INFER] int9: the characteristics of rhinoceroses and horses indicate that they might share a common ancestor [BECAUSE] int5 [AND] int9 [INFER] int10: rhinoceroses and horses might share a common ancestor
