A teenager is trying to prove how responsible he is. Choose ALL the statements that correctly use still, yet, or already.
The correct answers are I have already finished my math homework! and Are you still worried about my grades?
Already is perfect for affirmative sentences to show a task is complete.
Still works great in questions to ask if an ongoing state (like being worried) continues.
Yet cannot be used in a standard affirmative sentence ("have done... yet"), and negative sentences about unfinished tasks should end with yet, not already ("haven't fed... yet").
