Final answer:
The first proposal for the 17th Amendment was introduced in the Senate, and it eventually changed the selection of Senators to direct election by the people.
Step-by-step explanation:
The first proposal for the 17th Amendment was introduced in 1826 in the Senate. The 17th Amendment, which was ultimately passed in 1913, changed the selection of Senators from appointment by state legislatures to direct election by the people. This change came about due to scandalous elections in the late 1800s and early 1900s, which led to a public perception of Senators being selected based on personal connections rather than qualifications.
