Question

select the word that means ends for a period of time.
every january, the united states congress convenes in washington, d.c. in years when there is no federal election, congress generally remains in session until december. in election years, however, congress usually adjourns in october so that members can go home to campaign.
submit

Explanation:

To solve this, we analyze the context. The passage talks about Congress's session timing. "Adjourns" in election years (October) contrasts with remaining in session until December (non - election years). "Adjourns" means to end a meeting or session (a period of time). Other words in the passage: "convenes" means to start, "remains" means to stay, "campaign" is about election activities. So "adjourns" is the word that means ends for a period of time.

Answer:

adjourns
