Example Input: Paragraph- Sent 1: The National Security Act of 1947 created the position of Director of Central Intelligence (DCI).
Sent 2: Independent from the departments of Defense, State, Justice, and other policy departments, the DCI heads the U.S.intelligence community and provides intelligence to federal entities.
Sent 3: The sole element of the intelligence community independent from a cabinet agency is the CIA.
Sent 4: As an independent agency, it collects, analyzes, and disseminates intelligence from all sources.
Sent 5: The CIA's number one customer is the president of the United States, who also has the authority to direct it to conduct covert operations.

Sent 8: The director's power under federal law over the loose, confederated "intelligence community" is limited.
Sent 9: He or she states the community's priorities and coordinates development of intelligence agency budget requests for submission to Congress.

Sent 11: Neither is true.
Sent 12: In fact, the DCI's real authority has been directly proportional to his personal closeness to the president, which has waxed and waned over the years, and to others in government, especially the secretary of defense.
Sent 13: Intelligence agencies under the Department of Defense account for approximately 80 percent of all U.S. spending for intelligence, including some that supports a national customer base and some that supports specific Defense Department or military service needs.
Sent 14: As they are housed in the Defense Department, these agencies are keenly attentive to the military's strategic and tactical requirements.
