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 (", ").

Q: 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 were plans formed for building a great network of railways?.

A: 1, 2.

Q: Paragraph- Sent 1: It's strange how one can write delightedly of the happier moments of life, forgetting the things that one would forget by remembering fully the things one would remember, and suddenly the forgotten, in revenge, rears up to savage the unwary.
Sent 2: So it was as I wrote the preceding.
Sent 3: My heart convulsed, and I left this manuscript for a three-day spree.
Sent 4: Apparently I was so successful that it lasted a week and a half.
Sent 5: Not bad for an eighty-three-year-old, even for one who has his rejuve every month.
Sent 6: And if I can brag and digress so easily, this must not be painful enough to merit a mindwipe, yes?
Sent 7: No. I abandoned these notes to my future self to have the wipe done immediately, thinking that Bernardo Flynn should receive such services when he needed them, even should the need arise at the third hour after midnight.
Sent 8: My mindsmith is not so understanding.
Sent 9: She says I am emotionally a child, to which I reply, "Of course.
Sent 10: Why else would I come to you?"Sent 11: This logic does not soothe her; she says I must wait three weeks.
Sent 12: Three!.
Sent 13: Such is the law.
Sent 14: I say I do not care about law, I care about service and she should care about money.
Sent 15: Enough.
Sent 16: I went on a spree, and it must have been a good one.
Sent 17: I hope the wipe is as successful with my time on Vega IV as my spree was with my time here.
Sent 18: I dimly remember three bedpartners who were probably human, and one that I hope was delirium.
Sent 19: I will not answer the phone for a week, no matter whose face appears on it.
Sent 20: I keep evading the issue.
Question: What did this woman do?.
