Teacher: 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. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". 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. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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 Skarsgard) 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: Question: How old is Will Hunting in the movie ?, Answer: Twenty years
Reason: This is a good question which results in a factoid answer, and the answer is correct too.

Now, solve this instance: Loosely inspired by the true story of Gang Lu, a Chinese physics student, but with substantial differences in plot and character motivation, the film stars Liu Xing (Liu Ye), as a humble, but brilliant, Chinese student, who arrives at Valley State University and makes a bumpy transition into American life with the help of Joanna Silver (Meryl Streep), a wealthy university patron who takes a liking to the young student. Xing joins a select cosmology group under the direction of his hero, the famous cosmologist Professor Jacob Reiser (Aidan Quinn). The group is working to create a model of the origins of the universe, based on Reiser's theory. Xing's enormous talent leads him quickly to become Reiser's protege, and it seems that only hard work stands between him and a bright future in science. But Xing is obsessed with the study of dark matter, an unseen substance that he believes shapes the universe, and a theory that conflicts with the Reiser model. When Xing begins to make scientific breakthroughs of his own, he begins to encounter unexpected obstacles.
