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>
use the ancient exonym "Vlach". However, both groups use the endonym "Romanians", calling their language "Romanian" (română or rumână). In some notes of the government of Serbia, officials recognise that "certainly members of this population have similar characteristics with Romanians, and the language and folklore ride to their Romanian origin". The representatives of the Vlach minority sustain their Romanian origin. Legal status The ethnonym is Rumâni and the community Rumâni din Sârbie, translated into English as "Romanians from Serbia". They are also known in Romanian as Valahii din Serbia or Românii din Timoc. Although ethnographically and linguistically related to the Romanians, within the Vlach community there are divergences on whether or not they belong to the Romanian nation and whether or not their minority should be amalgamated with the Romanian minority in Vojvodina. In a Romanian-Yugoslav agreement of November 4, 2002, the Yugoslav authorities agreed to recognize the Romanian identity of the Vlach population in Central Serbia, but the agreement was not implemented. In April 2005, 23 deputies from the Council of Europe, representatives from Hungary, Georgia, Lithuania, Romania, Moldova, Estonia, Armenia, Azerbaïdjan, Denmark and Bulgaria protested against Serbia's treatment of this population. The Senate of Romania postponed the ratification of Serbia`s candidature for membership in the European Union until the legal status and minority right of the Romanian (Vlach) population in Serbia is clarified. Predrag Balašević, president of the Vlach party of Serbia, accused the government of assimilation by using the national Vlach organization against the interests of this minority in Serbia. Since 2010, the Vlach National Council of Serbia has been led by members of leading Serbian parties (Democrat Party and Socialist Party), most of whom are ethnic Serbs having no relation to the Vlach/Romanian minority. Radiša Dragojević, the current president of Vlach National Council of Serbia, who is not a Vlach, but an ethnic Serb, stated that no one has the right to ask the Vlach minority in Serbia to identify themselves as Romanian or veto anything. As a response to mister Dragojević`s statement, the cultural organizations Ariadnae Filum, Društvo za kulturu Vlaha - Rumuna Srbije, Društvo Rumuna - Vlaha „Trajan“, Društvo za kulturu, jezik i religiju Vlaha - Rumuna Pomoravlja, Udruženje za tradiciju i kulturu Vlaha „Dunav“, Centar za ruralni razvoj - Vlaška kulturna inicijativa Srbija and the Vlach Party of Serbia protested and stated that it was false. According to a 2012 agreement between Romania and Serbia, members of the Vlach community that choose to declare as Romanians will have access to education, media and religion in the Romanian language. Notable people Bojan Aleksandrović, (), priest, pastor of the Romanian Orthodox community in Malajnica and Remesiana, Serbia, and protopresbyter of Dacia Ripensis. Branko Olar, one of the best known singers of Romanian folklore from Eastern Serbia, originating from the village of Slatina near Bor Staniša Paunović, a well-known Romanian folklore singer, originating from Negotin, from Eastern Serbia See also Romanians of Serbia Vlachs in medieval Serbia Aromanians Vlachs of Croatia Romanians in Bulgaria References Sources Further reading Sorescu-Marinković, Annemarie.

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.
