In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: Passage: Paul Helfeld (also given as Hefeld), aged 21 in 1909, and Jacob Lepidus (also reported as Lapidus), who was 25 the same year, were Jewish-Latvian immigrants. They had been members of the Latvian Socialist Party and, although they had not held positions of responsibility, they had smuggled revolutionary literature into Russia for the party. The pair had been living in Paris in 1907, along with Lepidus's brother Paul, a revolutionary bomber who went under the nom de guerre "Strygia"; Jacob was described in The Times as a "member of a notorious Russian revolutionary family". On 1 May 1907 Paul Lepidus was killed when a bomb he was carrying to assassinate Armand Fallières, the President of France, exploded prematurely. Lepidus and Helfeld fled the country and lived in Scotland for a year, before moving to Tottenham.Both men joined a small group of Latvian agitators living in north London; according to other members of the group, the pair had criminal records and had joined as a cover for the robberies they carried out. Lepidus was employed, briefly, at a furniture factory, while Helfeld took a job at the Schnurmann rubber factory in Tottenham. Helfeld refused to give his name when he joined the company, so he was listed on the time sheets as "Elephant" in reference to his bulk. Situated on the corner of Tottenham High Road and Chesnut Road, the factory sat opposite Tottenham Police Station, which was under the control of the Metropolitan Police.Special Branch suspected another individual, the Russian revolutionary Christian Salnish, of having organised the robbery. Salnish, who often went under the name Jacob Fogel, had been an active revolutionary since the age of 13. He participated in the 1905 Russian Revolution and afterwards helped to build resistance groups in the Baltic states and Saint Petersburg, then the capital of Imperial Russia. Special Branch suspected a political element to the crime based on Salnish's involvement, but as both Helfeld and Lepidus died during the chase, the motivation for the crime was never established. 
Question: What is the first name of Paul's brother?
[EX A]: Jacob.

[EX Q]: Passage: In 1982, Toronto bank employee Dan Mahowny is given access to bigger and bigger accounts with his promotion to assistant branch manager. His boss trusts him, but is unaware that Mahowny is a compulsive gambler. Mahowny is soon skimming larger and larger amounts for his own use and making weekly trips to Atlantic City, where he is treated like a king by a competent casino manager. Mahowny's girlfriend, fellow bank employee Belinda, cannot understand what is happening. Mahowny's criminal acts come to light when Toronto police begin to investigate his longtime bookie Frank.
The movie's focus is on Mahowny as a character—how his compulsion drives him and all the domino effects it has on the rest of his life. The love story between Mahowny and Belinda and the inclusion of other finely drawn characters such as hapless casino employee Bernie put the emphasis squarely on the gambling addiction, not on the flash and sizzle of big casinos or multimillion-dollar frauds. 
Question: What is the first name of the person who has a bookie?
[EX A]: Dan.

[EX Q]: Passage: The Treaty of San Stefano was signed on 3 March 1878 by Russia and the Ottoman Empire. It was to set up an autonomous Bulgarian principality spanning Moesia, Macedonia and Thrace, roughly on the territories of the Second Bulgarian Empire, and this day is now a public holiday called National Liberation Day. The other Great Powers immediately rejected the treaty out of fear that such a large country in the Balkans might threaten their interests. It was superseded by the Treaty of Berlin, signed on 13 July, which provided for a much smaller state only comprising Moesia and the region of Sofia, leaving large populations of ethnic Bulgarians outside the new country. This significantly contributed to Bulgaria's militaristic foreign affairs approach during the first half of the 20th century.The Bulgarian principality won a war against Serbia and incorporated the semi-autonomous Ottoman territory of Eastern Rumelia in 1885, proclaiming itself an independent state on 5 October 1908. In the years following independence, Bulgaria increasingly militarized and was often referred to as "the Balkan Prussia". It became involved in three consecutive conflicts between 1912 and 1918—two Balkan Wars and World War I. After a disastrous defeat in the Second Balkan War, Bulgaria again found itself fighting on the losing side as a result of its alliance with the Central Powers in World War I. Despite fielding more than a quarter of its population in a 1,200,000-strong army and achieving several decisive victories at Doiran and Monastir, the country capitulated in 1918. The war resulted in significant territorial losses and a total of 87,500 soldiers killed. More than 253,000 refugees from the lost territories immigrated to Bulgaria from 1912 to 1929, placing additional strain on the already ruined national economy. 
Question: What was the full name of the treaty that the other Great Powers immediately reject?
[EX A]:
The Treaty of San Stefano.
