Final answer:
Members of Congress are encouraged to remain in session for longer periods of time due to their pursuit of reelection goals, access to resources, and state power.
Step-by-step explanation:
One reason that encouraged Congress to remain in session for longer periods of time is the pursuit of their reelection goals. Members of Congress have access to a variety of resources, such as salary, travel, office, staff, and communication allowances, which can be used to serve their election objectives. The structure of Congress also fosters a decentralized committee system that allows members to specialize in certain legislative areas, giving them a legislative platform to advocate for specific policies. Additionally, incumbents have the advantage of state power, including constituent casework and access to specialized information, which helps them support their constituents and gain voter support.
