Questions & Answers about Tú cocinas; mientras tanto, yo limpio.
The lesson is about using mientras with the subjunctive, so why do cocinas and limpio use the indicative here?
Because this sentence describes a present reality or an established plan, not a future hypothetical. When mientras (or mientras tanto) states a fact or an ongoing action, you use the indicative. The subjunctive is only used when mientras refers to a future duration or means 'as long as'.
What is the difference between mientras and mientras tanto?
Mientras is a conjunction meaning 'while' and needs to directly introduce a clause. Mientras tanto is an adverbial phrase meaning 'meanwhile' or 'in the meantime'. It stands alone to connect two independent ideas, which is why it is separated by a semicolon and a comma here.
Since Spanish usually drops subject pronouns, why are tú and yo included in this sentence?
Subject pronouns are used here for contrast. The speaker is dividing up chores: you do this, and I do that. Explicitly including tú and yo highlights this division of labor naturally.
Could I use the subjunctive here if I were suggesting this as a future plan?
