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 (", ").

Sent 2: The target remained in Indianapolis Center's airspace for another six minutes, then crossed into the western portion of Washington Center's airspace at 9:10.
Sent 3: As Indianapolis Center continued searching for the aircraft, two managers and the controller responsible for American 77 looked to the west and southwest along the flight's projected path, not east-where the aircraft was now heading.
Sent 4: Managers did not instruct other controllers at Indianapolis Center to turn on their primary radar coverage to join in the search for American 77.
Sent 5: In sum, Indianapolis Center never saw Flight 77 turn around.
Sent 6: By the time it reappeared in primary radar coverage, controllers had either stopped looking for the aircraft because they thought it had crashed or were looking toward the west.

Sent 9: They knew American 77 was lost.

Input: Consider Input: Paragraph- Sent 1: In his 1847 Report on Algeria, Tocqueville declared that Europe should avoid making the same mistake they made with the European colonization of the Americas in order to avoid the bloody consequences.
Sent 2: More particularly he reminds his countrymen of a solemn caution whereby he warns them that if the methods used towards the Algerian people remain unchanged, colonization will end in a blood bath.
Sent 3: Tocqueville includes in his report on Algeria that the fate of their soldiers and finances depended on how the French government treats the various native populations of Algeria, including the various Arab tribes, independent Kabyles living in the Atlas Mountains, and the powerful political leader Abd-el-Kader.
Sent 4: In his various letters and essays on Algeria, Tocqueville discusses contrasting strategies by which a European country can approach imperialism.
Sent 5: In particular, the author differentiates between what he terms 'dominance' and a particular version of 'colonization'.
Sent 6: The latter stresses the obtainment and protection of land and passageways that promise commercial wealth.
Sent 7: In the case of Algeria, the Port of Algiers, and the control over the Strait of Gibraltar, were considered by Tocqueville to be particular valuable.
Sent 8: Direct control of the political operations of the entirety of Algeria, however, was not.
Sent 9: Thus the author stresses domination over only certain points of political influence as a means to colonization of commercially valuable areas.
Sent 10: Tocqueville argued that domination via violent means, though unpleasant, is necessary for colonization and justified by the laws of war.
Sent 11: Such laws are not discussed in detail; however, given that the goal of the French mission in Algeria was to obtain commercial and military interest as opposed to self-defense, it can be deduced that Tocqueville would not concur with Just war theory's jus ad bellum criteria of just cause.
Sent 12: Further, given that Tocqueville approved of the use of force to eliminate civilian housing in enemy territory, his approach does not accord with Just War Theory's jus in bellow criteria of proportionality and discrimination.
Question: What does Tocqueville declare in his 1847 report?.
