Detailed Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
See one example below:
Problem: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Problem: 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.
Solution:
What are the full names of the two individuals who had smuggled revolutionary literature into Russia for the Latvian Socialist Party?
