Help the mad scientist claim his food in the breakroom! Choose the correct pair of words to complete his demand.

"Excuse me, but that glowing green sandwich is ___," declared the scientist. "Please don't touch ___ lunch!"

The correct answer is mine / my.

Use the possessive pronoun mine when the word stands alone without a noun after it ("the sandwich is mine"). Use the possessive determiner my when it comes directly before a noun to show ownership ("my lunch").
