oliver, anika, and jackson are playing a game on their computer. suddenly, jackson makes a wrong move. which button should he press to undo his last step?
Answer
Brief Explanations:
In most computer - based applications and games, the undo function is usually represented by an arrow curving to the left. Among the common symbols for undo, the left - pointing arrow is well - known. Assuming the left - pointing arrow is one of the options, we need to identify it.
Answer:
The button with the left - pointing arrow (usually the one that looks like ← among the given options, but the specific option number is not clear from the description as no visual indication of the arrow on the numbered buttons is given). If we assume the left - pointing arrow is on button 2 based on common UI design where the undo button is often an arrow curving left, the answer would be 2.
