Final answer:
A bill is introduced in the legislative process at the point where it is first presented in either the House of Representatives or the Senate, with the exception of tax bills which must originate in the House.
Step-by-step explanation:
The section of a chart which represents the point where a bill is introduced from the House and Senate would be where the legislative process begins. Bills can originate in either the House of Representatives or the Senate, except for revenue-raising bills, which Article I, Section 7 of the U.S.
Constitution requires to originate in the House. Typical legislative procedure dictates that a bill is introduced, assigned to a committee where it is debated and amended, and then sent to the floor of the respective chamber for further debate and amendments.
