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>
as circulating autoantibodies (i.e. antibodies directed against patients' own antigens), autoimmune hemolytic anemia, immune thrombocytopenic purpura, cold agglutinin disease, circulating anticoagulant antibodies, acquired von Willebrand disease, and angeoedema due to C1-esterase inhibitor deficiency. It is thought that the B-cell receptor binding of unidentified antigens including those involved in the cited autoimmune abnormalities stimulate the B-cells' proliferation, long-term survival, and thereby the step-wise acquisition of genomic abnormalities which ultimately cause the antigen-experienced B-cells to become malignant. The genomic abnormalities thought to contribute to this malignant transformation include: Chromosome abnormalities such as: 1) deletions in the long (i.e. "q") arm of chromosome 7 (annotated as del7q) in 30-40% of cases (this deletion is rare in other lymphomas and therefore used as a marker for SMZL); 2) deletion of a region on the short (i.e. "p") arm of chromosome 17 in 3-17% of cases to result in a loose of one of the two p53 genes that encode a tumor suppressor that acts to regulate cellular survival; and 3) gains in the q arm of chromosome 3 in 10-20% of cases. Mutations in genes such as: 1 KLF2 (21% of cases), a transcription factor that indirectly regulates the NF-κB signaling pathway of cellular survival, proliferation, and the production of cell-stimulating cytokines; 2) NOTCH2 (20% of cases), a membrane protein that regulates the development of marginal zone B-cells from their precursor cells and has tumor suppressor activity to thereby promote cellular survival; 3) TP53 (14% of cases), a transcription factor that indirectly regulates cell proliferation and programmed cell death to thereby promote cellular survival; 4) IGLL5 (14% of cases) with unclear functions; 5) TNFAIP3 (13% of cases), which acts indirectly to inhibit NF-κB activation and programmed cell death; and 6) in <10% of cases at least 16 other genes. Overall, mutations in the NOTCH, NF-κB, and KLF2 signaling pathways appear particularly important in the pathogenesis of SMZL. Diagnosis The clearest evidence for the diagnosis of SMZL is obtained by examination of patients' spleens obtained by splenectomy. These spleens characteristically show lymphoid infiltrates in the white pulp and, to a lesser and more variable extent, the red pulp. These infiltrates consist of small lymphocytes, marginal zone B-cells, centroblast-like B-cells, monocyte-like B-cells, and plasma cells. Epithelioid-like histiocytes may be found in the red pulp. Splenic hilar lymph nodes may show nodular infiltrates of small lymphocytes. Careful and thorough examination of patients' bone marrow commonly shows aggregates of lymphoid cells between the organs trabeculae and within its sinuses. Neoplastic B-cells may also circulate in patient's blood. The neoplastic cells in all of these tissues, similar the neoplastic cells in extranodal and nodal MZL, express CD20, CD27, and BCL2 but not CD10, CD23, CD5, CD43, CD38, BCL6, cyclin D1, or annexin A1 marker proteins. These cells may also express the del7q deletion (i.e. deletions in the q arm of chromosome 7) in 30-40% of cases and in lower percentages of cases the mutated genes listed in the Pathophysiology section. While the diagnosis of SMZL was initially based on the examination of splenic tissue, currently the diagnosis is made in most cases on clinical findings plus examinations of patients' bone marrow and/or blood that detect neoplastic B-cells that express some of the proteins and/or genomic abnormalities cited above; however, cases difficult to diagnose based on bone marrow and blood findings require examination of the spleen to obtain a definitive diagnosis of SMZL. Treatment Given its rarity, there have been no systematic and controlled studies on the treatment of SMZL. Current recommendations for this include the following. Watchful waiting, which is the withholding of specific treatments while performing follow-up examinations

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.
