Final answer:
Without knowing Katie's current score, we can't determine the exact card she needs to draw to reach a score of 0. Additional information is needed to provide an accurate answer to which card will bring her score to 0 in the Integer Game.
Step-by-step explanation:
The question pertains to integer addition to achieve a specific score in a game. In order to assist Katie in winning the game by reaching a score of 0, it is essential to know what her current score or the sum of integers in her hand is. Without this information, we cannot determine which card Katie would need to draw to reach the target score of 0. Therefore, we would need additional context, such as the current sum of her cards, to provide an accurate answer. If we assume she has a sum that is positive, she would require a negative integer of equal magnitude to reach 0. Conversely, if her sum is negative, she would need a positive integer with an equal magnitude.
