You are given a paragraph, a question and some answer options (associated with "A", "B", "C", "D", etc.) You need to list all the correct answer options with their associated letters (e.g. "A" can be a valid answer). Note that sometimes, more than one option can answer the question correctly and completely. In those cases, please generate all such options separated by a comma (e.g. "A, B" is a valid answer). Do not generate anything else apart from one or more of the following characters: 'A', 'B, 'C', 'D', etc.
One example: Paragraph- Sent 1: Obama was born on August 4, 1961, at Kapiʻolani Maternity & Gynecological Hospital in Honolulu, Hawaii.
Sent 2: He is the only President to have been born in Hawaii.
Sent 3: He was born to a white mother and a black father.
Sent 4: His mother, Ann Dunham (1942-1995), was born in Wichita, Kansas, of mostly English descent, with some German, Irish, Scottish, Swiss, and Welsh ancestry. Question: How old was Obama's mother when he was born? (A) teenager (B) in his 40s (C) mid 20s (D) almost twenty.
Solution is here: D.
Explanation: Obama was born in 1961. His mother was born in 1942 and 1961-1942=19. Therefore, "almost twenty" answers the question sufficiently.

Now, solve this: Paragraph- Sent 1: The Principals Committee had its first meeting on al Qaeda on September 4.
Sent 2: On the day of the meeting, Clarke sent Rice an impassioned personal note.
Sent 3: He criticized U.S. counterterrorism efforts past and present.
Sent 4: The "real question" before the principals, he wrote, was "are we serious about dealing with the al Qida threat?
Sent 5: Is al Qida a big deal?
Sent 6: Decision makers should imagine themselves on a future day when the CSG has not succeeded in stopping al Qida attacks and hundreds of Americans lay dead in several countries, including the US," Clarke wrote.
Sent 7: "What would those decision makers wish that they had done earlier?
Sent 8: That future day could happen at any time."Sent 9: Clarke then turned to the Cole."Sent 10: The fact that the USS Cole was attacked during the last Administration does not absolve us of responding for the attack," he wrote.
Sent 11: "Many in al Qida and the Taliban may have drawn the wrong lesson from the Cole: that they can kill Americans without there being a US response, without there being a price.". 
Question: On September 4, who criticized U.S. counterterrorism efforts? (A) Rice (B) President Clinton (C) President Bush (D) The Principals (E) Al Qaeda (F) Clarke (G) Cole.
Solution:
F.
