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>
of the noble family von Heußlein, built by Johann Dientzenhofer in 1706. The medieval chapel Marienkapelle was renewed and enlarged by Balthasar Neumann. The catholic parish church Herz-Jesu-Kirche (Church of the Sacred Heart of Jesus) was built in neo-gothic style in 1882 by Andreas Lohrey. The tower is 67 meters high. The Jakobuskirche (Church of St. James) was the old catholic parish church of Bad Kissingen. The tower dates back to the 14th century, the church - replacing a medieval predecessor - was built from 1772 to 1775 by Johann Philipp Geigel in classicist style. The Lutheran church Erlöserkirche (Church of the Savior) was erected in 1847 according to the plans of the architect Friedrich von Gärtner, and expanded in 1891 according to the plans of August Thiersch. The Russian Orthodox Church of Saint Sergius of Radonesh, consecrated in 1901, was designed by the tsar's architect Viktor Schröter (St. Petersburg) in a neo-byzanthine style and erected by the architect Carl Krampf (Kissingen) for the then very numerous Russian spa guests. The Anglican Church of 1862 for the British spa guests was sold to the Lutheran community in 1953. The dilapidated building was replaced by the Lutheran community center in 1968. Between 1838 and 1913, the arcade (Arkadenbau) was built around the spa garden by Friedrich von Gärtner, as well as the halls for the use of the mineral water ("Brunnenhalle") and for promenades ("Wandelhalle"), following a design by Max Littmann. Littmann also designed the Kurtheater (spa theatre), completed in 1905, and the concert hall Regentenbau, inauguratet in 1913. The train station building, with its Renaissance revival façade, was built in 1874 under the supervision of Friedrich Bürklein. The KissSalis Therme was opened in 2004. It is one of the largest wellness baths in Europe, and the largest building project in the town since World War II. Another point of interest is the casino in the spa park.

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.
