Quizplus · Accepted Answer

"Until" is the best choice here because it indicates that the speaker cannot go to sleep until they finish studying for their economics exam. "As" and "since" both indicate a reason for something, but they do not necessarily imply that the action of studying needs to be completed before the speaker can go to sleep.
