question: Mary is taking measurements of the amount of oxygen in samples of water. If she measured the total levels of dissolved oxygen in a sample at 70 degrees fahrenheit and compared it to a sample at 80 degrees fahrenheit, which would contain more dissolved oxygen?
choices.text: 80 degrees fahrenheit 70 degrees fahrenheit
choices.label: A B
para: Warm water cant hold as much dissolved oxygen as cool water, so an increase in the temperature of water decreases the amount of oxygen it contains.
para_anno.effect_prop: dissolved oxygen
para_anno.cause_dir_str: increase
para_anno.effect_dir_str: decrease
para_anno.cause_dir_sign: MORE
para_anno.effect_dir_sign: LESS
para_anno.cause_prop: water temperature
question_anno.more_effect_dir: more
question_anno.less_cause_prop: fahrenheit
question_anno.more_effect_prop: dissolved oxygen
