Question: Runoff from farms that use fertilizers is entering a small lake. This will most directly affect the lake by causing
Answer: algae to grow in the lake.
Hypothesis: runoff entering a lake affects that lake by causing algae to grow in it
Supporting facts: sent1: a lake is a kind of body of water sent2: fertilizers have a positive impact on algae growth sent3: fertilizers are a source of pollution sent4: a plant requires water to grow sent5: green plants are a kind of producer sent6: a pond is a kind of body of water sent7: runoff enters a lake sent8: causing is a kind of affecting sent9: if something causes something else then that something else depends on that something sent10: as the amount of a source of something decreases , the amount of that something will decrease sent11: roots are a part of a plant / tree sent12: high runoff causes flooding sent13: if something enters into something else, then the contents of that something will enter that something else sent14: if something is a source of something else then that something usually contains that something else sent15: algae is found in bodies of water sent16: if something causes a process then that something is required for that process sent17: in the erosion process roots of plants are an inhibitor sent18: runoff contains chemicals / fertilizer / pollutants / pesticides from cropland sent19: the contents of something means the things that something contains sent20: if something affects a part of something else then that something affects that something else sent21: producing is similar to causing sent22: roots anchor plants into the soil sent23: if something has a positive impact on something else then that something causes that something else sent24: a plant requires photosynthesis to grow / survive sent25: pollution has a negative impact on the environment / air quality / water quality / society
Reasoning: [BECAUSE] if something enters into something else, then the contents of that something will enter that something else [AND] the contents of something means the things that something contains [INFER] int1: if something enters something else then the things that something contains will enter that something else [BECAUSE] int1 [AND] runoff enters a lake [INFER] int2: if runoff enters a lake then the things that runoff contains will enter that lake [BECAUSE] int2 [AND] runoff contains chemicals / fertilizer / pollutants / pesticides from cropland [INFER] int3: if runoff enters a lake then fertilizer will enter that lake [BECAUSE] a lake is a kind of body of water [AND] algae is found in bodies of water [INFER] int4: algae is found in a lake [BECAUSE] int4 [AND] fertilizers have a positive impact on algae growth [INFER] int5: fertilizers have a positve impact on algae growth in a lake [BECAUSE] int3 [AND] int5 [INFER] int6: runoff entering a lake has a positive impact on algae growth in that lake [BECAUSE] int6 [AND] if something has a positive impact on something else then that something causes that something else [INFER] int7: runoff entering a lake causes algae to grow in that lake [BECAUSE] int7 [AND] causing is a kind of affecting [INFER] int8: runoff entering a lake affects that lake by causing algae to grow in it
