Final answer:
The temperance movement was indeed influenced by new social conditions, such as increased urbanization and immigration, which is true. This movement sought to address the perceived moral decline associated with alcohol consumption, leading to Prohibition in the 1920s.
Step-by-step explanation:
The statement 'The temperance movement stemmed in part from new social conditions such as increasing urbanization and immigration' is true. The temperance movement in the United States gained momentum in the 19th and early 20th centuries, amidst transformative social conditions including rapid urbanization and a significant increase in immigration. These changes led to social strife and challenges, and the temperance movement emerged as a reaction to concerns about moral decay and social order, partly blamed on the consumption of alcohol.
The temperance movement advocated for the reduction or prohibition of alcohol consumption, which eventually led to the enactment of Prohibition in the 1920s under the 18th Amendment. Sections of the law made the transportation or importation of intoxicating liquors into any State, Territory, or possession of the United States illegal if it was in violation of local laws, as reflected in the provided reference.
