Important Notice
A mistake was discovered in Question 4 of Story 3 after the game was submitted .
The question incorrectly implies that the battery connection directly affects the EMF , which is not scientifically correct . The question should have been based on resistance instead .
To avoid confusion, please skip the question. For the game's progression, option C is considered the correct answer within the game system, even though it is not the scientifically correct answer.
Thank you for your understanding.
