question: If Jim is trying to lower the melting point of an isomer, what should he do to the number of branching points of the isomer?
choices.text: decrease them increase them
choices.label: A B
para: The more branching there is in isomers, the lower the boiling and melting points are.
para_anno.effect_prop: melting points
para_anno.cause_dir_str: more
para_anno.effect_dir_str: lower
para_anno.cause_dir_sign: MORE
para_anno.effect_dir_sign: LESS
para_anno.cause_prop: branching there is in isomers
question_anno.less_effect_dir: lower
question_anno.less_cause_prop: branching points
question_anno.less_effect_prop: melting point
question_anno.less_cause_dir: melting point
