Input: Consider Input: Paragraph- Sent 1: Before 9/11, the CIA did not invest in developing a robust capability to conduct paramilitary operations with U.S. personnel.
Sent 2: It relied on proxies instead, organized by CIA operatives without the requisite military training.
Sent 3: The results were unsatisfactory.
Sent 4: Whether the price is measured in either money or people, the United States cannot afford to build two separate capabilities for carrying out secret military operations, secretly operating standoff missiles, and secretly training foreign military or paramilitary forces.
Sent 5: The United States should concentrate responsibility and necessary legal authorities in one entity.
Sent 6: The post-9/11 Afghanistan precedent of using joint CIA-military teams for covert and clandestine operations was a good one.
Sent 7: We believe this proposal to be consistent with it.
Sent 8: Each agency would concentrate on its comparative advantages in building capabilities for joint missions.
Sent 9: The operation itself would be planned in common.
Sent 10: The CIA has a reputation for agility in operations.
Sent 11: The military has a reputation for being methodical and cumbersome.
Sent 12: We do not know if these stereotypes match current reality; they may also be one more symptom of the civil-military misunderstandings we described in chapter 4.
Sent 13: It is a problem to be resolved in policy guidance and agency management, not in the creation of redundant, overlapping capabilities and authorities in such sensitive work.
Sent 14: The CIA's experts should be integrated into the military's training, exercises, and planning.
Sent 15: To quote a CIA official now serving in the field:"One fight, one team."Sent 16: Finally, to combat the secrecy and complexity we have described, the overall amounts of money being appropriated for national intelligence and to its component agencies should no longer be kept secret.
Sent 17: Congress should pass a separate appropriations act for intelligence, defending the broad allocation of how these tens of billions of dollars have been assigned among the varieties of intelligence work.
Sent 18: The specifics of the intelligence appropriation would remain classified, as they are today.
Question: What did the CIA rely on before 9/11 to work with US personnel?.

Output: Proxies organized by CIA operatives without the requisite military training.

Input: Consider Input: Paragraph- Sent 1: But I think it is certain that most of the early Christians understood these words of our Lord's ascension and coming again in glory.
Sent 2: They believed that He was coming again in a very little while during their own life-time, in a few months or years, to make an end of the world and to judge the quick and the dead.

Sent 6: Hundreds of years passed, and yet Christ did not come in glory.
Sent 7: And, as I said, a sadness fell on all the Church.
Sent 8: Surely, they said, this is the time of which Christ said we were to weep and lament till we saw Him again--this is the time of which He said that the bridegroom should be taken from us, and we should fast in those days.
Sent 9: And they did fast, and weep, and lament; and their religion became a very sad and melancholy one--most sad in those who were most holy, and loved their Lord best, and longed most for His coming in glory.
Question: At what time should Christians fast?.
Output: The time when the bridegroom was taken away.
