[EX Q]: Mr. Flip is a 1909 American silent comedy film made by Essanay Studios, directed by Gilbert M. 'Broncho Billy' Anderson and starring Ben Turpin.
[EX A]: What production company was involved in Mr. Flip?

[EX Q]: Somatic mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) gene are present in lung adenocarcinomas that respond to the EGFR inhibitors gefitinib and erlotinib. Two types of mutations account for approximately 90% of mutated cases: short in-frame deletions in exon 19 and a specific point mutation in exon 21 at codon 858 (L858R). Screening for these mutations has been based mainly on direct sequencing. We report here the development and validation of polymerase chain reaction-based assays for these two predominant types of EGFR mutations. The assay for exon 19 mutations is based on length analysis of fluorescently labeled polymerase chain reaction products, and the assay for the exon 21 L858R mutation is based on a new Sau96I restriction site created by this mutation. Using serial dilutions of DNAs from lung cancer cell lines harboring either exon 19 or 21 mutations, we detected these mutations in the presence of up to approximately 90% normal DNA. In a test set of 39 lung cancer samples, direct sequencing detected mutations in 25 cases whereas our assays were positive in 29 cases, including 4 cases in which mutations were not apparent by sequencing. These assays offer higher sensitivity and ease of scoring and eliminate the need for sequencing, providing a robust and accessible approach to the rapid identification of most lung cancer patients likely to respond to EGFR inhibitors.
[EX A]: Mutations in which gene determine response to both erlotinib and gefitinib?

[EX Q]: The man sitting opposite Robert was the Financial Controller. Everybody called him "the FC" for short. He made all the decisions about money. Robert needed some more. That was why he had to see him. The two men did not get on very well. In fact, they had always disliked each other. "Your request is out of the question," the FC said. Robert had difficulty in controlling himself, but he managed somehow. He explained that he wanted the money in order to make more programmes. "And why do you want to do that?" the FC asked sharply. Again, Robert almost lost his temper. "Because more and more people are listening to my department's programmes. There's great demand for them," he answered. The FC did not seem to believe him. But Robert had a report on the numbers of listeners to all EBC programmes. The FC became less confident. Robert threw the report down on the table and told him to read it. The FC looked at it in silence. The figures proved that he had been wrong, but he did not want to admit it. "Well," he finally said, "I may have made a small mistake." Robert noticed the word "may." He got up to leave. But he had the feeling that he would get the money after all.

Who do you think won the argument in the end?
