worked outmy homework." (Unless you mean you solved complex math problems in it). Correct: "Ifinishedmy homework." or "Icompletedmy homework." - Incorrect: "She
worked outher degree." Correct: "Sheearnedher degree." or "Sheachievedher degree."

Work outdoes not mean to physically remove something from a confined space. - Incorrect: "The dentist

- For Spontaneous Resolution without Implied Effort: While
work outcan mean a situation resolves successfully, it usually implies some preceding effort, planning, or the natural progression of events. If something happens without any direct intervention or process, other verbs are more appropriate. - Debatable: "The problem
worked itself out." (Less common and implies some unseen natural resolution, rather than active problem-solving). More Natural: "The problemresolved itself." or "The issueblew over."
