Task: Question Generation
Input (English): Passage: A floatplane navigates through the Pacific Northwest, landing in Burrard Inlet. As the well-dressed passenger emerges, CIA covert operations officer Richard Malone targets him in his crosshairs, but he is unable to pull the trigger. He tells his CIA control officer Jaime that he has reached his limit and is quitting the agency.  He burns his Maryland driver's license and heads inland. His Ford Mustang breaks down in a rural Oregon valley. Malone pushes it to a gas station and garage owned by Paul Barlow, who runs the station with his 17-year-old daughter Jo. Barlow suggests the fastest way to repair the car is to tow it 60 miles to a larger service station. Malone opts to wait for the necessary parts to arrive. Paul invites Malone to stay in the spare room.  Malone and Paul become friends as they discuss their respective military service in the Vietnam War.
Jo snoops through Malone's possessions, finding a pistol. Malone helps Paul with his repair work and sizes up the town, which is under the thumb of Charles Delaney, who buys up all the property he can and forces people to sell if they first refuse.  Delaney is a wealthy white ultra-nationalist who runs a right-wing terrorist group. A group of Delaney's thugs harass Malone and Jo on a bridge and refuse to let them pass. Malone defends himself when he is attacked. He severely beats the ringleader, Dan Bollard, sending him to the hospital. Dan's brother, Calvin, is goaded into killing Malone by Delaney's main henchman Madrid.  Calvin tries to shoot Malone at the local barber shop but Malone shoots and kills Calvin instead.
Output (English): What is the ;ast name of the person who tells someone that they have reached their limit?
