Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Example Input: Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy. "Our most important finding was the difference between Canadians and the others," said Professor Michel Claes,the lead author of the study."Canadians focus on independence and negotiation.On the other hand,Italians,for example,exercise more control.We found Canadians seem to focus on negotiation in case of a conflict." Claes said Canada,France and Italy were selected for the study because they share important cultural and social factors."We chose FrenchCanadians because they share the same language as France,and originally came from France and share certain values.Italy was included because it was considered to have similar,strong and important family values," he explained. The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old. Canadian students reported less control and more free actions,according to the study.Italian parents were stricter and French parents were somewhere in the middle. Claes explains that the differences lie in education in Canada,France and Italy. "North America has its own educational values,which promote individualization.Tolerance and comprehension are encouraged.Italy,on the other hand,promotes respect of authority,control,and the need for permission." he said. Children from all three countries described their mothers as warm and communicative.Italian and Canadian children had similar feelings about their fathers,and reported high levels of emotional ties.But French fathers were generally thought by their children to be more distant and cold. "We were surprised by this," Claes admitted."It seems as though the relationships between French mothers and their children were becoming closer over time,while fathers maintain a form of distance and coldness,which is more of a source of conflict in France than in the other countries."
Example Output: According to Michel Claes,what mainly leads to the differences in parentchildren relationships among Canada,France and Italy?

Example Input: It has been previously shown that disruption of RAD26 in yeast strain W303-1B results in a strain that is deficient in transcription-coupled repair (TCR), the preferential repair of the transcribed strand of an expressed gene over the non-transcribed strand and the rest of the genome. RAD26 encodes a protein that is homologous to Cockayne syndrome group B protein (CSB) and is a member of the SWI2/SNF2 family of DNA-dependent ATPases involved in chromatin remodeling. Like the rad26 mutant, cells from Cockayne syndrome patients are defective in TCR. We examined the role of Rad26 in TCR by disrupting RAD26 in two repair-proficient laboratory strains and, remarkably, observed no effect upon TCR. Our results indicate that disruption of RAD26 alone is insufficient to impair TCR. Thus, W303-1B must already possess a mutation that, together with disruption of RAD26, causes a deficiency in TCR. We suggest that other genes are mutated in Cockayne syndrome cells that contribute to the deficiency in TCR. Surprisingly, deletion of RAD26 results in expression of genes that are repressed by flanking transposon delta elements, an Spt(-) phenotype. The delta elements appear to perturb local chromatin structure. Expression of genes flanked by delta elements in rad26Delta mutants is consistent with a role for Rad26 in chromatin remodeling.
Example Output: Which gene strand is targeted by transcription-coupled repair (TCR)?

Example Input: "Just ate chicken feet for lunch. " These were the words I wrote on my blog yesterday. By the next day there were hundreds of comments from my friends. They ranged from "OH MY GOD! That is so disgusting! " to "What were they like?" to "Why can't you eat sandwiches like everyone else?" To Chinese people, chicken feet are a normal snack. To my friends in Britain, the thought of eating a chicken's foot is----well, weird . As weird, in fact, as eating a bullfrog, scorpion , snake, or turtle. But if there are two things I love more than anything else in life, they are: trying new things and food. I arrived in Beijing five months ago. Since then, I've searched for the "weirdest" foods so I can try them, then treat my friends to some "virtual eating" on my blog. One weekend, I went to Wangfujing, Beijing's "snack street". The trip gave me tons of blog material. "I chose a stick with three live, wriggling scorpions on it," I wrote. "And it was pretty good. The scorpion was warm and crispy. The legs did have a tendency to get stuck between one's teeth, however. What's more, I am sure scorpion number two stung me with its tail in revenge ." Next came snake: "A bit like a cross between fish and chicken, with a slightly rubbery texture and meaty taste." Some people were actually angry when I ate turtle soup----especially when I posted pictures showing the poor little guy's head staring sadly up at us from the bowl. "I am never speaking to you again," wrote one (former) friend. Still, I will continue my culinary quest. Next on my list is starfish, though I feel I should have some vegetables too----algae, maybe. So what am I eating, tonight, you may ask. Pizza. Well, a girl's gotta have a break sometimes.
