Question: A car has a small gasoline engine combined with a battery-powered electric motor. When the car stops at a red light, the gasoline engine stops running and the electric motor begins working. How does this type of car most likely benefit people?
Answer: uses less gasoline
Hypothesis: an electric car has a positive impact on the environment / air quality / water quality / society by using less gasoline
Supporting facts: sent1: electricity is a kind of alternative fuel sent2: using a gasoline engine requires burning gasoline sent3: pollution has a negative impact on the environment / air quality / water quality / society sent4: an electric motor is a kind of electrical device sent5: as the use of alternative fuels increases , the use of gasoline will decrease sent6: if a certain something decreases the use of a resource then that certain something uses less of that resource than a regular something sent7: if a machine contains a part then that machine uses that part sent8: an electric car is a kind of machine sent9: using less of something negative has a positive impact sent10: an electric car contains an electric motor sent11: an electrical device can be a part of a machine sent12: burning gasoline / oil is a source of air pollution sent13: an electrical device uses electricity to operate
Reasoning: [BECAUSE] as the use of alternative fuels increases , the use of gasoline will decrease [AND] if a certain something decreases the use of a resource then that certain something uses less of that resource than a regular something [INFER] int1: something that uses alternative fuels uses less gasoline than a regular something [BECAUSE] electricity is a kind of alternative fuel [AND] an electrical device uses electricity to operate [INFER] int2: an electrical device uses alternative fuel to operate [BECAUSE] int2 [AND] an electric motor is a kind of electrical device [INFER] int3: an electric motor uses alternative fuel to operate [BECAUSE] int1 [AND] int3 [INFER] int4: a something that uses an electric motor uses less gasoline than a regular something [BECAUSE] an electric car contains an electric motor [AND] an electric car is a kind of machine [INFER] int5: an electric car is a kind of machine that contains an electric motor [BECAUSE] an electrical device can be a part of a machine [AND] if a machine contains a part then that machine uses that part [INFER] int6: if a machine contains an electrical device then that machine uses that electrical device [BECAUSE] int6 [AND] an electric motor is a kind of electrical device [INFER] int7: if a machine contains an electric motor then that machine uses that electric motor [BECAUSE] int5 [AND] int7 [INFER] int8: an electric car uses an electric motor [BECAUSE] int4 [AND] int8 [INFER] int9: electric car uses less gasoline than a regular car [BECAUSE] burning gasoline / oil is a source of air pollution [AND] using a gasoline engine requires burning gasoline [INFER] int10: using gasoline is a source of pollution [BECAUSE] int10 [AND] pollution has a negative impact on the environment / air quality / water quality / society [INFER] int11: using gasoline has a negative impact on the environment / air quality / water quality / society [BECAUSE] int11 [AND] using less of something negative has a positive impact [INFER] int12: using less gasoline has a positive impact on the environment / air quality / water quality / society [BECAUSE] int12 [AND] int9 [INFER] int13: an electric car has a positive impact on the environment / air quality / water quality / society by using less gasoline
