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>
an EMZL. Another key factor in the initiation of many EMZL cases is chronic inflammation caused by a chronic infection or autoimmune reaction. The chronic inflammation stimulates B-cells to rearrange their immunoglobulin heavy chain locus so that they encode B-cell receptors that recognize unnatural antigens presented by the injured issues and/or infectious agents that underlie the inflammation. This rearrangement results in the B-cells responding to the ab\normal antigens by taking on features of marginal B-cells and proliferating excessively. In consequence, these B cells progressively acquire in a step-wise fashion chromosome abnormalities, gene mutations, and/or dis-regulated genes that contribute to their becoming malignant. The acquired genomic abnormalities found in EMZL along with the frequency of occurrence in specific EMZL subtypes include the following. Chromosome translocations: 1) A translocation of the long (or "q") arm of chromosome 11 at position 21 with the q arm of chromosome 16 at position 21 (notated as a t(11;18)(q21;q21) translocation) occurs in 24% of gastric, 38% of lung, and rarely other EMZL subtypes. This translocation places a part of the API2 gene with a part of the MALT1 gene to create a fusion gene that encodes an Api2-Malt1 fusion protein. This chimeric protein promotes the continuous activation of a transcription factor, NF-κB. NF-κB controls the expression of various genes which increase the survival, cytokine production, and other potentially malignant behaviors of cells. 2) A t(14;18)(q32;q21) translocation occurs in 7% of ocular adnexa, 6% of lung, and rarely if at all in other cases of EMZL. It causes the overexpression of Malt1. This protein indirectly inhibits programmed cell death to prolong cell survival and also promotes activation of NF-κB. 3) A t(1;14)(p22;q32) ("p" stands for a chromosome's short arm) translocation occurs in ∼9% of lung, ∼4% of stomach, and rarely if at all in other cases of EMZL. This translocation causes the overexpression of the BCL10 gene. Bcl10 protein contributes to the activation of NF-κB. 4) A t(3;14)(p13;q32) translocation occurs in rare cases of EMZL and is thought to cause overexpression of the FOXP1 gene. FoxP1 protein stimulates production of transcription factors such as PRDM1, IRF4, and XBP1 which promote the maturation of B-cells to plasma cells. 5) Three translocations, t(1;14)(p21;q32), t(5;14)(q34;q32), t(9;14)(p24;q32), and t(X;14)(p11.4;q32), occur in rare cases of EMZL but their effects on promoting malignancy are unknown. Gene inactivations and mutations: 1) Inactivation or the TNFAIP3 gene due to its deletion on chromosome 6 about position 23 (i.e. a 6q23 deletion) or its mutation occur mainly in ocular adnexa, salivary gland, and thyroid gland EMZL. TNFAIP3 inactivation generally takes place in cases which do not have any of the above chromosome translocations. This gene's product, tumor necrosis factor, alpha-induced protein 3, functions to impair the activation of NF-κB. 2) Gain-of-function mutations in the MYD88 gene occur in ~5% of ocular adnexa EMZL cases. The product of this gene, myeloid differentiation primary response 88, continuously activates NF-κB as well as the STAT3 and AP1 transcription factors. 3) Inactivating mutations in the NOTCH1 (8% of all cases) and NOTCH2 (8% of all cases) genes occur in EMZL. The products of these genes are cell surface receptor proteins which when bound to their activating ligands move to the cell nucleus and contribute to the activation of genes that control the development, proliferation, survival, and migration of B cells. Many EMZL subtypes are associated with infectious agents or autoimmune diseases that may contribute to their malignant development. The following Table reports on these EMZL subtypes; the tissues they involve; the infectious agents/autoimmune diseases that may underlie the development of the EMZL subtypes; the strength of evidence linking these infectious

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.
