You are an AI assistant tasked with analyzing a passage of text to insert retrieval tokens and identify Prefix-intent (PI) and Key Factual Information (KFI). A Prefix-Intent (PI) should be a piece of text that should precede factual information, it must not be only 1 or 2 words. Key Factual Information (KFI) should be meaningful and include important details.

Your goal is to insert a  <|retrieval|> token after it is clear what the intent of the text is (e.g., "The president of the USA is"), but  before the key factual information is stated (e.g., "Joe Biden"). Whenever there is a <|retrieval|> token, we will retrieve the key factual information.

Here is the passage you will be working with:

<passage>
Battle Command Training Center-Leavenworth Battle Command Training Center - Leavenworth (BCTC-Lvn) provides battle command and staff training, training support, and publications to Army National Guard Soldiers and units, at its facility in Fort Leavenworth, Kansas, USA, or via mobile training teams, prior to mobilization to assist them prepare for full-spectrum operations in a joint, interagency, intergovernmental, and multinational environment. It was founded in 1991 by the National Guard (NG), in close cooperation with the Combined Arms Center (CAC), Kansas National Guard (KSNG), and the 35th Infantry Division (Mechanized), with the purpose of improving Army National Guard (ARNG) division battle command and staff training. BCTC-Lvn has incrementally improved and expanded since its founding. The BCTC-Lvn is one of three ARNG Battle Command Training Centers within the Battle Command Training Capability Program (BCTCP). The other two centers are located at Camp Dodge, Iowa and Fort Indiantown Gap, Pennsylvania. BCTC-Lvn is not to be confused with the Mission Command Training Program (MCTP) (formerly designated the Battle Command Training Program, or BCTP), also at Fort Leavenworth, Kansas. The MCTP, a subordinate organization of CAC, is tasked to provide full-spectrum operations training support for senior commanders and their staffs (brigade-level and above). BCTC-Lvn works with the MCTP to provide this training for ARNG battalion, brigade, and division commanders and their staffs. BCTC-Lvn provides the facilities, networks, equipment, and life support for ARNG units conducting MCTP-led, full-spectrum exercise rotations. Background In the early 1980s, the National Guard Bureau (NGB), CAC, and the Adjutant General, State of Kansas (TAG-KS) envisioned constructing a combined federal facility to serve as a training center in support of ARNG division battle staff exercises required by the US Army Forces Command (USFORSCOM) and to provide a facility to host the Headquarters, 35th Infantry Division. The Army licensed land on Fort Leavenworth, KS to TAG-KS to build a facility with funding from NGB. This facility would serve the dual purpose as an armory and division training center for the newly activated 35th Infantry Division. The original organization, the Leader Development Center, later became a federal field operating agency of the NGB, with the mission to support the same battle command and staff training for the ARNG, as it was for Army Active Component units. BCTC-Lvn also hosts ARNG division-level full spectrum exercises and the 35th Infantry Division headquarters. Major milestones 1982 – Vision by NGB, CAC, and TAG-KS to create an ARNG training center. 1985 – Military construction plan submitted to build armory and training center on land leased by TAG-KS from Fort Leavenworth. 1989 – Construction of original facility (Bldg 1951) began. 1990 – Construction of original facility completed; Memorandum of Agreement (MOA) between CAC, NGB, TAG-KS, and 35th Infantry Division authorizing construction and mutual use of a reconfigurable standard command post facility. 1991 – Leader Development Center achieved initial operational capability; Battle Command Training Program (BCTP) pilot rotation for ARNG divisions conducted at the Leader Development Center; construction increased space in the main facility and added separate tactical operations center (TOC) buildings. 1993 – The Brigade Command and Battle Staff Training Program (BCBST) begun for ARNG enhanced separate brigades (later combined into BCTP exercises). 1994 – Director, ARNG; Commander, CAC; and TAG-KS sign memorandum of understanding (MOU) establishing and defining the operational relationships between the LDC, CAC, and KSNG. 1997/1998 – Building 1952, TOCs Five and Six, Building Eight, and additional parking constructed. 1999 – Command, Control, Communications, Computers, and Intelligence Support Team formed, later to become the Army Battle Command Systems Support Team (ABCS-ST). 2000 – Current MOA among Director, ARNG; Commander, CAC; and TAG-KS signed; full-time staff transitioned to

Follow these steps to complete the task:

1. Inserting retrieval tokens:
   a. Read through the text carefully.
   b. Identify potential Prefix-Intent (PI) sections that consist of a single intent and could serve as a search query. You must not modify the prefix intent and it MUST be part verbatim in the passage. It cannot be single or only a few words.
   c. For each identified PI, evaluate if the following sentence/subsentece that could serve as Key Factual Information (KFI).
   d. Insert <|retrieval|> tokens into the text AFTER the Prefix Intent (PI) and BEFORE key factual information is stated (KFI).
   e. Key Factual information should not intersect with Prefix Intent.

2. Identifying Prefix-Intent (PI) and Key Factual Information (KFI):
   a. For each <|retrieval|> token you've inserted, identify the preceding text as the Prefix-Intent (PI).
   b. Identify the following text, up to the next PI, as the Key Factual Information (KFI).
   c. Ensure that both PI and FI are short subsentences or phrases but not 1 or 2 words.

3. Insert <|start-PI|>,<|end-PI|>, <|start-KFI|>, <|end-KFI|>.
   a. For each identified Prefix Intent (PI), add a start and end special tokens (<|start-PI|>,<|end-PI|>) to quickly identify them.
   b. Do the same for the Key Factual Information (KFI) (<|start-KFI|>, <|end-KFI|>)
   c. Ensure that the very first PI in the passage is preceded by <|start-PI|>.
   d. Double-check that every PI and KFI is properly enclosed in these tags.

4. Describing ideal retrieved information:
   a. Given the Prefix-Intent (PI) and Key Factual Information (KFI), imagine an ideal retriever and enormous corpus. 
   b. Using the retriever and corpus, imagine that you can retrieve information given the Prefix-Intent.  
   c. Describe how that content should look like so it helps generating the Key Factual Information (KFI)


5. Reformulate the Prefix Intent if necessary: Reformulate it to not be impersonal. This means that if the subject it is not identified (e.g. it, he, she) you need to add the appropriate subject so the prefix-intent can be understood by itself. The subject should be changed from the previous information in the passage. Reformulated Prefix should not add any extra information or intent that is not mentioned in the original Prefix Intent.


6. Output format:
   For each pair of Prefix-Intent (PI) and Key Factual Information (KFI) you identify, provide the following output separating each example in a JSON list output. Ensure that it is actually a JSON.

   - Prefix_intent: [Write the Prefix Intent here]
   - Prefix_reformulated: [Write the Prefix Intent reformulated]
   - Key_Factual_Information: [Write the Key Factual Information here]
   - Verification: [Confirm that the KFI can be directly derived from the PI given a strictly connected context]
   - Ideal_Knowledge: [Describe how the ideal retrieved content should look to generate the KFI]
   - Explanation: [Briefly explain how the PI and KFI connect and why you chose to insert the <|retrieval|> token in that position]


7. Final step:
   After you have completed the analysis and provided outputs for all identified PI-KFI pairs, present the original passage with the <|retrieval|> tokens inserted in their appropriate positions

Here's an example of the expected output format:

Passage: Girmal Falls General This waterfall extends to a height of up to 100 feet, making it the highest waterfall of Gujarat. The picturesque beauty of this site makes it popular among visitors and people of the region alike. The water swiftly falls from a great height, creating a fog like condition that’s eye catching. The government of this state is working on many projects to make this place an ideal picnic spot and a tourist attraction. The fall comes to its best form at the time of monsoon and provides an immensely striking appearance. Some of the best natural features of Gujarat can be explored in this place. This place is a nice and refreshing retreat for any traveler.
