You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

Paragraph- Sent 1: Assisting Zionist causes Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors.
Sent 2: Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university.
Sent 3: He also submitted various suggestions as to its initial programs.
Sent 4: Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land.
Sent 5: That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development.
Sent 6: Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important.
Sent 7: Chaim Weizmann later became Israel's first president.
Sent 8: Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post.
Sent 9: The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons".
Sent 10: Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it.
Question: Who presented the offer of the ceremonial position of president to Einstein?.

Paragraph- Sent 1: Soon after the conclusion of peace, important changes were made in legislation concerning industry and commerce, and the new freedom thus afforded produced a large number of limited liability companies.
Sent 2: Plans were formed for building a great network of railways, partly for the purpose of developing the natural resources of the country, and partly for the purpose of increasing its power for defense and attack.
Sent 3: The existence of serfdom was tackled boldly, taking advantage of a petition presented by the Polish landed proprietors of the Lithuanian provinces and, hoping that their relations with the serfs might be regulated in a more satisfactory way (meaning in a way more satisfactory for the proprietors), he authorized the formation of committees "for ameliorating the condition of the peasants," and laid down the principles on which the amelioration was to be effected.
Sent 4: This step had been followed by one even more significant.
Sent 5: Without consulting his ordinary advisers, Alexander ordered the Minister of the Interior to send a circular to the provincial governors of European Russia (serfdom was rare in other parts), containing a copy of the instructions forwarded to the Governor-General of Lithuania, praising the supposed generous, patriotic intentions of the Lithuanian landed proprietors, and suggesting that perhaps the landed proprietors of other provinces might express a similar desire.
Sent 6: The hint was taken: in all provinces where serfdom existed, emancipation committees were formed.
Sent 7: The emancipation was not merely a humanitarian question capable of being solved instantaneously by imperial ukase.
Sent 8: It contained very complicated problems, deeply affecting the economic, social and political future of the nation.
Sent 9: Alexander had to choose between the different measures recommended to him and decide if the serfs would become agricultural laborers dependent economically and administratively on the landlords or if the serfs would be transformed into a class of independent communal proprietors.
Sent 10: The emperor gave his support to the latter project, and the Russian peasantry became one of the last groups of peasants in Europe to shake off serfdom.
Sent 11: The architects of the emancipation manifesto were Alexander's brother Konstantin, Yakov Rostovtsev, and Nikolay Milyutin.
Sent 12: On 3 March 1861, 6 years after his accession, the emancipation law was signed and published.
Question: When was the emancipation law signed?.

Paragraph- Sent 1: Albanian was proved to be an Indo-European language in 1854 by the German philologist Franz Bopp.
Sent 2: The Albanian language comprises its own branch of the Indo-European language family.
Sent 3: Some scholars believe that Albanian derives from Illyrian while others claim that it derives from Daco-Thracian.
Sent 4: (Illyrian and Daco-Thracian, however, might have been closely related languages; see Thraco-Illyrian.) Establishing longer relations, Albanian is often compared to Balto-Slavic on the one hand and Germanic on the other, both of which share a number of isoglosses with Albanian.
Sent 5: Moreover, Albanian has undergone a vowel shift in which stressed, long o has fallen to a, much like in the former and opposite the latter.
Sent 6: Likewise, Albanian has taken the old relative jos and innovatively used it exclusively to qualify adjectives, much in the way Balto-Slavic has used this word to provide the definite ending of adjectives.
Sent 7: The cultural renaissance was first of all expressed through the development of the Albanian language in the area of church texts and publications, mainly of the Catholic region in the North, but also of the Orthodox in the South.
Sent 8: The Protestant reforms invigorated hopes for the development of the local language and literary tradition when cleric Gjon Buzuku brought into the Albanian language the Catholic liturgy, trying to do for the Albanian language what Luther did for German.
Question: Of the languages that scholars compare to Albanian language, which is most closely related to the Albanian language and why?.
