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 7: It was a boy of some six or seven years, and so covered with blood that it seemed it must be dead.

[EX Q]: Paragraph- Sent 1: The conquerors, having disarmed the conquered, have imposed their economic conditions, their absurd moralities and territorial humiliations, as those imposed on Bulgaria, Turkey and Hungary, conditions which are sufficiently difficult to be maintained.
Sent 2: And as the ferment of hate develops, the conquerors do not disarm.
Sent 3: Above all, the little States do not disarm, who have wanted too much, have obtained too much, and now do not know how to maintain what they have.
Sent 4: In many countries for certain social reasons war has become an industry; they live by the state of war.
Sent 5: What would they do without a state of war?
Sent 6: In general, then, Europe has considerably more men under arms than in 1913.
Sent 7: Not only has it not disarmed, as the Entente always declared would be the consequence of the victory of the principles of democracy, but the victors are always leaning toward further armament.
Sent 8: The more difficult it becomes to maintain the conditions of the peace, because of their severity and their absurdity, the more necessary it is to maintain armies.
Sent 9: The conquered have not armies; the conquerors are, or, perhaps, up to a short time ago, were sure that the big armies would serve to enforce the payment of the indemnities.
Sent 10: Now, in fact, they would not serve for anything else.
Question: Who does "not serve for anything else"?.
