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>
Angelus Silesius Angelus Silesius (9 July 1677), born Johann Scheffler and also known as Johann Angelus Silesius, was a German Catholic priest and physician, known as a mystic and religious poet. Born and raised a Lutheran, he adopted the name Angelus (Latin for "angel" or "heavenly messenger") and the epithet Silesius ("Silesian") on converting to Catholicism in 1653. While studying in the Netherlands, he began to read the works of medieval mystics and became acquainted with the works of the German mystic Jacob Böhme through Böhme's friend, Abraham von Franckenberg. Silesius's mystical beliefs caused tension between him and Lutheran authorities and led to his eventual conversion to Catholicism. He took holy orders under the Franciscans and was ordained a priest in 1661. Ten years later, in 1671, he retired to a Jesuit house where he remained for the rest of his life. An enthusiastic convert and priest, Silesius worked to convince German Protestants in Silesia to return to the Roman Catholic Church. He composed 55 tracts and pamphlets condemning Protestantism, several of which were published in two folio volumes entitled Ecclesiologia (i.e., Ecclesiology). He is now remembered chiefly for his religious poetry, and in particular for two poetical works both published in 1657: Heilige Seelenlust (literally, "The Soul's Holy Desires"), a collection of more than 200 religious hymn texts that have been used by Catholics and Protestants; and Cherubinischer Wandersmann ("The Cherubinic Pilgrim"), a collection of 1,676 short poems, mostly Alexandrine couplets. His poetry explores themes of mysticism, quietism, and pantheism within an orthodox Catholic context. Life Early life and education While his exact birthdate is unknown, it is believed that Silesius was born in December 1624 in Breslau, the capital of Silesia. The earliest mention of him is the registration of his baptism on Christmas Day, 25 December 1624. At the time, Silesia was a German-speaking province of the Habsburg Empire. Today, it is the southwestern region of Poland. Baptized Johann Scheffler, he was the first of three children. His parents, who married in February 1624, were Lutheran Protestants. His father, Stanislaus Scheffler (–1637), was of Polish ancestry and was a member of the lower nobility. Stanislaus dedicated his life to the military, was made Lord of Borowice (or Vorwicze) and received a knighthood from King Sigismund III. A few years before his son's birth, he had retired from military service in Kraków. In 1624, he was 62. The child's mother, Maria Hennemann (–1639), was a 24-year-old daughter of a local physician with ties to the Habsburg Imperial court. Scheffler obtained his early education at the Elisabethsgymnasium (Saint Elizabeth's Gymnasium, or high school) in Breslau. His earliest poems were written and published during these formative years. Scheffler was probably influenced by the recently published works of poet and scholar Martin Opitz and by one of his teachers, poet Christoph Köler. He subsequently studied medicine and science at the University of Strasbourg (or Strassburg) in Alsace for a year in 1643. It was a Lutheran university with a course of study that embraced Renaissance humanism. From 1644 to 1647, he attended Leiden University. At this time, he was introduced to the writings of Jacob Böhme (1575–1624) and became acquainted with one of Böhme's friends, Abraham von Franckenberg (1593–1652), who probably introduced him to ancient Kabbalist writings, alchemy, and hermeticism, and to mystic writers living in Amsterdam. Franckenberg had been compiling a complete edition of Böhme's work at the time Scheffler resided in the Netherlands. The Dutch Republic provided refuge to many religious sects, mystics, and scholars who were persecuted elsewhere in Europe. Scheffler then went to Italy and enrolled in

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.
