Answer:
revolves
**Rule**: The **Simple Present Tense** is used for universal truths and scientific facts. **Correct Usage**: The movement of the earth around the sun is a permanent fact.

(b) 'is revolving' (Present Continuous) would imply this is a temporary action. (c) 'has revolved' (Present Perfect) is grammatically incorrect in this context.

appears
**Rule**: **Stative Verbs**. 'Appear' (meaning 'seem') is a stative verb and is not used in continuous tenses. The indefinite pronoun 'Everything' is singular. **Correct Usage**: The singular verb 'appears' correctly agrees with the singular subject 'Everything'. **Incorrect Options**: (a) 'appear' is a plural verb. (c) 'is appearing' is grammatically incorrect. (d) 'have appeared' is plural and the wrong tense.

Answer:
departs
**Rule**: The **Simple Present Tense** is used for future events that are part of a fixed schedule or timetable. **Correct Usage**: Airline schedules are fixed, so even though the event is in the future ('tomorrow'), the simple present 'departs' is the correct form.
