What you will do你要做什么

• You will see 45 pairs of short animal-animation videos, side by side. 你会看到 45 组并排播放的动物动画短视频。
• For each pair, read the text description, watch both videos, then answer 4 questions — for each question, pick the video (Left or Right) you think is better. 每组请先读文字描述,看完两个视频后回答 4 个问题,每题从左/右中选出你认为更好的一个。
• There is no “correct” answer — go with your impression. You must pick one side for every question. 没有标准答案,凭你的直观感受选择;每题必须二选一。
• Videos loop automatically; use the Replay button to restart both together. 视频自动循环播放,可点击"同时重播"让两边从头播放。
• Your progress is saved in this browser — if the page reloads, you can continue where you left off. 进度会自动保存在浏览器里,刷新后可以继续。

Works on both computers and phones — a laptop/desktop gives the best view. On a phone the two videos play side by side; watch both before answering. 电脑和手机都可以完成——电脑观看效果最佳;手机上两个视频会并排播放,请都看完再作答。
