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>
Wetter, Hesse Wetter (Hessen) is a small town in Hesse, Germany. The rather unusual designation Wetter (Hessen-Nassau) stems from a time when the town belonged to the Prussian province of the same name, and nowadays is only used by the railway – even today, the railway station in town bears this name. Geography Wetter lies in the Marburg-Biedenkopf district on the western edge of the Burgwald, a low range of hills, in the Wetschaft valley and neighbouring places about 14 km north of Marburg. Neighbouring communities To the north, Wetter borders on the town of Rosenthal in Waldeck-Frankenberg district, to the east on the town of Rauschenberg and the community of Cölbe, to the south on the community of Lahntal, to the southwest on the community of Dautphetal, and to the southwest on the town of Biedenkopf and the community of Münchhausen am Christenberg, all in the Marburg-Biedenkopf district. Transport North to south through the town's municipal area runs the Federal Highway (Bundesstraße) B 252 from eastern Westphalia by way of Korbach and Frankenberg and on to Göttingen (in the community of Lahntal). To divert heavy traffic away from places in the Wetschaft valley, a bypass road is planned. The Burgwaldbahn railway line connects the town with Marburg and Frankenberg. The Kurhessenbahn which runs the line means to reopen the extension between Frankenberg and Korbach. History Wetter was already being mentioned in documents in the 8th and 9th centuries; it was mentioned in one such document under the same name that it still has today in 1108, and the "Weistum of Wetter" was already displaying its town rights even as early as 1239. Politics Town council As of municipal elections held on 26 March 2006, the seats on Wetter Town Council are apportioned thus: Coat of arms Wetter's civic coat of arms might be described thus: In Or on a three-knolled hill vert a fleur-de-lis twig vert with three blossoms argent flanked by two inescutcheons, dexter in azure the Hessian Lion rampant gules and argent sinister; sinister in gules the wheel of Mainz argent. The two inescutcheons (smaller shields within the main one) hark back to the time when the Hessian Landgraves held sway (the Hessian Lion), and to the Archbishops of Mainz (the wheel of Mainz). Constituent communities Amönau Mellnau Niederwetter Oberndorf Oberrosphe Todenhausen Treisbach Unterrosphe Warzenbach Wetter Culture and sightseeing Buildings The Gothic monastery church (13th century). Town Hall – in the upper floors slated half-timbering with a spire skylight, built about 1680. The ground floor is massive. Recently expanded. Former synagogue – (once a storeroom, since renovated and turned into an event room). Two-floor square half-timbered building with polygonal ridge turret, late 19th century. Houses – The compact and picturesque townscape consists first and foremost of half-timbered houses with forward-facing gables, most of which have slate roofs or plasterwork. After several town fires, only a few buildings from before 1629 have still been preserved. Some houses exhibit Classicist doors. Remains of the mediaeval town wall with two towers. The houses at the following addresses are worth mentioning: Markt 7 – Three-floor house with forward-facing gable and a corner oriel window. On the stone ground floor a pretty Renaissance portal, marked 1570. Markt 8 – 17th century. Markt 9 – Three-floor house with forward-facing gable, presumably from the first third of the 16th century, second upper floor added about 1700. Markt 14 – Baroque half-timbered building with ornamental carvings, presumably from the late 17th century. Krämergasse 14 – House with side gables with carved infilling boards, dated 1671. Krämergasse 10 – Two-floor half-timbered building, possibly from first quarter

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.
