Question: A negative effect of the invention and use of paper is the
Answer: increased number of trees cut down.
Hypothesis: a negative effect of the invention and use of paper is an increased number of trees cut down
Supporting facts: sent1: dead plants means dead plant material sent2: destroying animal habitats has a negative impact on an ecosystem sent3: adverse effect means negative impact sent4: paper is a kind of tool sent5: creating paper requires cutting down trees sent6: destroying a forest means cutting down the trees in that forest sent7: destroying something decreases the amount of that something sent8: cutting down a forest means cutting down the trees in that forest sent9: using paper requires creating paper sent10: killing means harming something causing death sent11: cutting down trees has a negative impact on an ecosystem / organisms living in an ecosystem sent12: if something is allowed to be used then the use of that something might increase sent13: cutting means changing the object from a whole into smaller pieces sent14: if something has a negative impact on something else then increasing the amount of that something has a negative impact on that something else sent15: deforestation is the process of cutting down trees sent16: destroying something causes harm to that something sent17: killing means changing a living thing from alive to dead by harming sent18: preventing something decreases the amount of that something sent19: to change means to have an effect sent20: an impact means an effect sent21: humans changing ecosystems / environments usually has a negative impact on an ecosystem / organisms living in an ecosystem sent22: if something requires something else then increasing that something requires an increase in that something else sent23: inventing a tool allows / enables that tool to be used sent24: a sheet of paper is a kind of object sent25: cutting down trees in a forest causes the number of trees to decrease in that forest
Reasoning: [BECAUSE] inventing a tool allows / enables that tool to be used [AND] paper is a kind of tool [INFER] int1: inventing paper allows paper to be used [BECAUSE] int1 [AND] if something is allowed to be used then the use of that something might increase [INFER] int2: inventing paper might increase the use of paper [BECAUSE] creating paper requires cutting down trees [AND] using paper requires creating paper [INFER] int3: using paper requires cutting down trees [BECAUSE] int3 [AND] if something requires something else then increasing that something requires an increase in that something else [INFER] int4: an increased use of paper requires an increase in the number of trees cut down [BECAUSE] cutting down trees has a negative impact on an ecosystem / organisms living in an ecosystem [AND] if something has a negative impact on something else then increasing the amount of that something has a negative impact on that something else [INFER] int5: increasing the number of trees cut down has a negative impact on the environment [BECAUSE] int4 [AND] int5 [INFER] int6: an increased use of paper has a negative effect on the environment by increasing the number of trees cut down [BECAUSE] int2 [AND] int6 [INFER] int7: the invention and increased use of paper has a negative impact on the environment by increasing the number of trees cut down [BECAUSE] int7 [AND] an impact means an effect [INFER] int8: a negative effect of the invention and use of paper is an increased number of trees cut down
