Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

Example Input: In the movie Predator  (1987), near the climax, when the Predator finds Arnold, it did not try to kill him immediately. Instead, it goes near him and checks his head and removes its helmet (I am assuming that it would be its helmet).   Why did it not kill Arnold immediately as it killed everybody else? Did checking Arnold's head mean something?
Example Output: Why did the Predator not kill Arnold immediately as it killed everybody else?

Example Input: In Game Of Thrones Season 4, the wildling Craster leaves his sons, from his wives (at the same time his daughters), into the woods to be taken by the White Walkers' king, after that he turned them into new White Walkers. I tried to figure out the reason behind this event, but no clues.  So, What is the story behind this action? And why does the White Walkers' king need those new born babies?
Example Output: Why does Craster give those sacrifices to the White Walkers?

Example Input: Why was Dawson not called to testify that he was ordered to operate Code Red?
Example Output:
Why was Dawson not called to testify?
