Final answer:
It is true that a restaurant can lose its liquor license if alcohol is over-served, as regulators aim to prevent alcohol-related incidents. Moreover, the temperance movement was indeed influenced by new social conditions like urbanization and immigration.
Step-by-step explanation:
The statement that a restaurant can lose its liquor license if an employee over-serves alcohol to customers is true. Licensing bodies have strict regulations regarding the service of alcohol, and over-serving can lead to numerous negative consequences, including the revocation of a liquor license. This is meant to prevent alcohol-related incidents and protect public safety.
The temperance movement indeed stemmed from new social conditions such as increasing urbanization and immigration. The movement was a social and political push towards the moderation or outright prohibition of alcohol consumption, and it gained momentum in response to the perceived moral and social issues that accompanied the rapid changes of the time, including the growth of cities and the influx of immigrants.
