程序运行时，在文本框Text1中输入“ABC123xyz”，在标签框Label1中输出“bcd123yza”，则划线处的代码为
图a
请回答下列问题：

场景：主界面 |
进入方式：由“片头”场景单击“进入”按钮进入 |
|
呈现方式： ⒈大雁挥动翅膀从舞台左下角飞到舞台右上角。 ⒉枫叶从树枝上飘落到草地上。 ⒊白云变换着形状飘向舞台右侧。 ⒋点击退出按钮，停止所有声音，跳转到“片尾”场景第一帧并停止播放。 |
呈现顺序说明： ⒈一开始出现背景图片和“雁飞”动画并播放背景音乐。 ⒉ 1秒后出现 “落叶”动画。 ⒊ 2秒后出现“白云”动画。 ⒋最后出现“退出”按钮，并停止动画播放，背景音乐继续播放。 |
根据制作脚本，背景音乐的同步方式为（数据流/事件）。
