Question: A student is investigating a light bulb that saves energy and can last up to 10 times longer than other bulbs. Other than saving energy, which is another benefit of using these light bulbs?
Answer: Less trash is put in landfills.
Hypothesis: a benefit of increasing the time that a lightbulb lasts is  decrease in the amount of trash discarded in landfills
Supporting facts: sent1: a light bulb is a kind of tool for seeing in the dark sent2: an example of managing the use of something is using less of that something sent3: decreasing something negative has a positive impact on a thing sent4: using less of a resource means conserving that resource sent5: as the amount of a source of something decreases , the amount of that something will decrease sent6: to last longer means to be available longer sent7: less means a reduced amount sent8: garbage means waste sent9: humans move waste to a landfill for disposal / storage sent10: if an object is discarded in a landfill then that object is trash sent11: light pollution is made of light sent12: studying is similar to investigating sent13: as the time a tool lasts increases , the number of tools discarded will decrease sent14: if a human discards an object then that object will become waste sent15: a light bulb is a kind of object sent16: if something is eliminated then the amount of that something decreases sent17: light bulb means lightbulb sent18: if the amount of / quantity of something stops decreasing then the amount of / quantity of that something may increase sent19: light means light energy sent20: performing a task in less time / more quickly / faster has a positive impact on a person 's life sent21: if something does not have to be replaced for a long time then that something will save money sent22: to dispose of something can mean to discard something sent23: length of time means period of time sent24: something that has a positive impact on something else is a kind of benefit sent25: landfills have a negative impact on the environment
Reasoning: [BECAUSE] a light bulb is a kind of tool for seeing in the dark [AND] as the time a tool lasts increases , the number of tools discarded will decrease [INFER] int1: as the time a lightbulb lasts increases, the number of lightbulbs discarded will decrease [BECAUSE] to dispose of something can mean to discard something [AND] humans move waste to a landfill for disposal / storage [INFER] int2: humans discard waste in a landfill [BECAUSE] int2 [AND] landfills have a negative impact on the environment [INFER] int3: humans discarding waste in a landfill has a negative impact on the environment [BECAUSE] int3 [AND] if a human discards an object then that object will become waste [INFER] int4: humans discarding objects in a landfill has a negative impact on the environment [BECAUSE] int4 [AND] decreasing something negative has a positive impact on a thing [INFER] int5: decreasing the number of objects discarded in landfills by humans has a positive impact on the environment [BECAUSE] int5 [AND] a light bulb is a kind of object [INFER] int6: decreasing the number of light bulbs discarded in landfills by humans has a positive impact on the environment [BECAUSE] int1 [AND] int6 [INFER] int7: increasing the time that a lightbulb lasts has a positive impact on the environment by decreasing the number of light bulbs discarded in landfills [BECAUSE] if an object is discarded in a landfill then that object is trash [AND] a light bulb is a kind of object [INFER] int8: if a light bulb is discarded in a landfill then that lightbulb is trash [BECAUSE] int7 [AND] int8 [INFER] int9: increasing the time that a lightbulb lasts has a positive impact on the environment by decreasing the amount of trash discarded in landfills [BECAUSE] int9 [AND] something that has a positive impact on something else is a kind of benefit [INFER] int10: a benefit of increasing the time that a lightbulb lasts is  decrease in the amount of trash discarded in landfills
