question: Fred has an isotope that decays slowly. What is likely true about it?
choices.text: it can be used to date older specimens it can't be used to date old specimens
choices.label: A B
para: Because these isotopes decay more slowly, they can be used to date much older specimens.
para_anno.effect_prop: use to date specimens
para_anno.cause_dir_str: more slowly
para_anno.effect_dir_str: older
para_anno.cause_dir_sign: LESS
para_anno.effect_dir_sign: MORE
para_anno.cause_prop: isotopes decay
question_anno.more_effect_dir: can be used to date
question_anno.less_effect_dir: can't be used to date
question_anno.less_cause_prop: isotope
question_anno.more_effect_prop: older specimens
question_anno.less_effect_prop: older specimens
question_anno.less_cause_dir: older specimens
