Question: What advantage do sea stars gain from having radial symmetry?
Answer: They sense predators and potential food from all directions.
Hypothesis: radial symmetry has a positive impact on an animal's survival by allowing it to sense predators / food from all directions
Supporting facts: sent1: as the distance from a source of something increases , that something will decrease sent2: eating prey requires catching prey sent3: an animal needs to eat food for nutrients sent4: preventing something decreases the amount of that something sent5: to be in danger means to be around / to be near something dangerous sent6: being able to sense things from all directions improves something's senses sent7: radial symmetry means an animal has similar body parts dispersed in all directions around a central axis sent8: avoiding something requires sensing that something sent9: if an organism eats something then that something is a source of frood to that organism sent10: if an animal is eaten by other animals , then the animal will be the prey sent11: avoiding predators has a positive impact on an organism 's survival sent12: finding something requires sensing that something sent13: sense is a kind of characteristic of an animal sent14: the senses are used for making observations sent15: sense is used for obtaining information about one 's environment sent16: avoiding predators / escaping predators / avoiding consumers is a kind of protection sent17: to prey on an animal means to eat that animal sent18: attracting something to a location causes that something to be near that location sent19: a predator usually kills its prey to eat it sent20: sensing food has a positive impact on finding food sent21: avoiding predators is synonymous with avoiding being eaten sent22: an animal can sense things in the direction that their specialized body parts for sensing are facing sent23: sensing is performed by specialized body parts sent24: avoiding is similar to preventing sent25: danger has a negative impact on a thing
Reasoning: [BECAUSE] sensing is performed by specialized body parts [AND] radial symmetry means an animal has similar body parts dispersed in all directions around a central axis [INFER] int1: an animal with radial symmetry has specialized body parts for sensing dispersed in all directions around a central axis [BECAUSE] int1 [AND] an animal can sense things in the direction that their specialized body parts for sensing are facing [INFER] int2: an animal with radial symmetry can sense predators / food from all directions [BECAUSE] avoiding predators has a positive impact on an organism 's survival [AND] avoiding something requires sensing that something [INFER] int3: sensing predators has a positive impact on an animal's survival [BECAUSE] sensing food has a positive impact on finding food [AND] an animal needs to eat food for nutrients [INFER] int4: sensing food has a positive impact on an animal's survival [BECAUSE] int3 [AND] int4 [INFER] int5: better senses have a positive impact on an animal 's survival [BECAUSE] int5 [AND] being able to sense things from all directions improves something's senses [INFER] int6: being able to sense things from all directions has a positive impact on an animal's survival [BECAUSE] int2 [AND] int6 [INFER] int7: radial symmetry has a positive impact on an animal's survival by allowing it to sense predators / food from all directions
