Final answer:
Members of Congress seek committee positions that align with their expertise and the needs of their constituency, such as the Agriculture Committee for representatives from states with large agricultural interests.
Step-by-step explanation:
Members of Congress bring to their roles a variety of specific experiences, interests, and levels of expertise, and try to match these to committee positions. For example, House members from states with large agricultural interests will typically seek positions on the Agriculture Committee. Senate members with a background in banking or finance may seek positions on the Senate Finance Committee. Members can request these positions from their chambers' respective leadership, and the leadership also selects the committee chairs.
