If you were a reform minded person who loathed the social problems associated with alcohol, you would have been especially sympathetic to the C.) WCTU or the Women's Christian Temperance Union. The WCTU was working to bring about prohibition and to make alcohol illegal.
Because it involved deciding what rights people should have, which was a hard job. The decisions they had to make involved alcohol, slavery, trade, and many other topics.
To amend the Constitution, the amendment must apply to all of America, and must have a major impact on all Americans. If it doesn't, the amendment won't be passed.
Hope this helped you out!
