Answer: A, B, and C
Explanation:
All of the above can happen while the bill is in committee.
GATHERS INFORMATION THROUGH HEARING
A committee would need to evaluate the merits and demerits of a particular bill before they can propose it. They do this through hearings usually to a subcommittee, which will then present it's findings to the whole committee.
DECISION TO SEND TO FLOOR
After a bill has been evaluated, the committee has the discretion to send the bill to the floor of the House to continue along the legislative process. The Speaker of the house may set time limits on the committee and failure to work on a bill is equivalent to killing it.
CHANGES LANGUAGE OF BILL
The Committee will hold a 'mark-up' session where the bill may be revised and additions made. If the additions are substantial, the bill can reintroduced as a 'clean-bill' which will have a new number as well as the proposed changes.
