解析上图题目---**Extraction Content:** **Section Title:** 六、解决问题。(18分) **Question 1:** 他们俩还要折多少只才能完成任务? **Associated Diagram/Image Description:** The image shows two children sitting at a table. There are several folded paper objects (likely paper cranes) on the table. Each child has a speech bubble next to them. * The child on the left has a speech bubble saying "我们俩要折78只鸟". * The child on the right has a speech bubble saying "我已经折了25只". * Below the child on the right, there is another speech bubble saying "我已经折了27只". (This seems to contradict the bubble next to the child, or perhaps the right child spoke second). Assuming the bubbles point to the individuals, the one on the right states "我已经折了27只". The bubble on the left seems to represent both children's target. **Other Relevant Text:** * Speech bubble near the left child: "我们俩要折78只鸟" (We two need to fold 78 birds). * Speech bubble near the right child: "我已经折了27只" (I have already folded 27 birds). * Speech bubble near the child on the left (or referring to both): "我已经折了25只" (I have already folded 25 birds). *Correction: The bubble saying "我已经折了25只" is positioned near the child on the left, while the bubble saying "我已经折了27只" is near the child on the right.* **Refined Interpretation of Speech Bubbles:** * Child on the left says: "我已经折了25只". * Child on the right says: "我已经折了27只". * A general statement, likely the goal for both: "我们俩要折78只鸟". **Summary of Problem Data:** * Total target number of birds to fold: 78 * Birds folded by the first child: 25 * Birds folded by the second child: 27
