Final answer:
The claim about intoxication assault being criminal only due to intoxication is false; the crime is enhanced due to intoxication, but the base act is already criminal. The temperance movement was motivated by new social conditions like urbanization and immigration, which is true.
Step-by-step explanation:
The statement that the crime of intoxication assault punishes conduct that would not otherwise be criminal except for the fact that the offender was intoxicated is false. Intoxication assault typically refers to an offense where an individual causes serious bodily harm to another person as a result of operating a vehicle or another form of machinery while intoxicated. The severity of the crime is enhanced by the fact that the offender was intoxicated, but the underlying conduct, such as reckless driving leading to injury, is criminal regardless of the intoxication status.
By contrast, the temperance movement indeed stemmed in part from new social conditions such as increasing urbanization and immigration, making the statement true. This movement was in response to various societal problems that were thought to be exacerbated by alcohol consumption, including poverty, street crime, and domestic violence.
