In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.
One example: Twenty-year-old Will Hunting of South Boston is a self-taught, genius-level intellect, though he works as a janitor at the Massachusetts Institute of Technology and spends his free time drinking with his friends, Chuckie (Ben Affleck), Billy (Cole Hauser) and Morgan (Casey Affleck). When Professor Gerald Lambeau (Stellan Skarsgård) posts a difficult mathematics problem as a challenge for his graduate students, Will solves the problem anonymously, stunning both the graduate students and Lambeau himself. As a challenge to the unknown genius, Lambeau posts an even more difficult problem. Lambeau chances upon Will solving the problem but Will flees the scene. That night at a bar, Will meets Skylar (Minnie Driver), a British student about to graduate from Harvard, who plans on attending medical school at Stanford and gives Will her phone number before leaving.
Solution is here: How old is Will Hunting in the movie ?
Explanation: This is a good question which has a factoid answer.

Now, solve this: Anderson (Duvall) is a successful American hitman whose employer sends him to do a job in Argentina. His contacts inform him that his target is a former general who took part in Argentina's last military dictatorship. Following a meeting with one of the co-conspirators, Anderson hears music and is shown a tango studio. He is immediately entranced by the dancing and wants to learn more about it, which leads to his meeting with Manuela, a local tango dancer and instructor.Things are not as easy as they seem. Anderson learns that the assassination job will be delayed, due to his target sustaining an injury in a riding accident. A paranoid Anderson simultaneously rents a room in two different hotels. From the safety but close proximity of one hotel room, he witnesses police converge on the other hotel. Anderson will fulfill his obligation to do the job despite the obvious reality that there is a leak. In the meantime, Anderson begins to immerse himself in the world of the tango, while balancing his plans to carry out the hit. The conspirator Miguel (Rueben Blades) is harshly interrogated by Buenos Aires police. Miguel can eventually breathe a sigh of relief when his conspirator within the Argentinian federal authorities shows up. Anderson eventually makes it out of Argentina safely.
Solution:
How was Anderson's taget injured?
