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>
Itzik Manger Itzik Manger (30 May 1901, Czernowitz, then Austrian-Hungarian Empire – 21 February 1969, Gedera, Israel) () was a prominent Yiddish poet and playwright, a self-proclaimed folk bard, visionary, and 'master tailor' of the written word. A Jew from Bucovina, Manger lived in Romania, Poland, France, England and finally Israel. Early life Manger was born to a Jewish family in Czernowitz, Austria-Hungary (later Cernăuți, Romania and now Chernivtsi, Ukraine) in 1901. His father, Hillel Manger, was a skilled tailor in love with literature, which he referred to as 'literatoyreh' (a portmanteau of the Yiddish words literatura and Toyreh). As a teenager, Manger attended the Kaiserlich-Königliches III. Staatsgymnasium in Czernowitz, where he studied German literature until he was expelled for pranks and bad behaviour. He exchanged this traditional education for the backstage atmosphere of the Yiddish theatre. Young poet In 1921, Manger began publishing his early poems and ballads in several new literary journals founded in the aftermath of World War I. Soon afterwards, he settled in Bucharest and wrote for the local Yiddish newspapers while giving occasional lectures on Spanish, Romanian, and Gypsy folklore. In 1927, Manger came to Warsaw, the spiritual and intellectual center of Ashkenazi Jewry and "the most inspiring city in Poland." Manger lived in the capital of the Yiddish cultural world for the next decade, which became the most productive years of his entire career. In 1929, Manger published his first book of poetry, Shtern afn dakh (Stars on the Roof), in Warsaw to critical acclaim. By the following year, Manger was so well known that he was admitted to the select Yiddish P.E.N. club, along with Isaac Bashevis, Israel Rabon, and I. Papiernikov. Literary success Between 1929 and 1938, Manger took the Warsaw literary world by storm. He gave frequent readings of his own poetry at the Writers' Club, was interviewed by all the major Warsaw Yiddish papers, published articles in the prestigious journal Literarishe Bleter (Literary Pages), issued his own literary journal called Chosen Words filled with his poetry, fiction, and artistic manifestos. At the same time, Manger continued to publish his own works, including a series of modernist poems inspired by the Oral Torah (Itzik's Midrash, 1935), a dramatic rewriting of the Purim story (Songs of the Megillah, 1936), a loose adaptation of Abraham Goldfaden's The Witch of Botoşani (Hotzmakh's Shpiel, 1937), a series of fictional vignettes on the history of Yiddish literature (Familiar Portraits, 1938), and three more volumes of poetry (Lantern in the Wind, 1933; Velvl Zbarzher Writes Letters to Malkele the Beautiful, 1937; and Twilight in the Mirror, 1937). Working with Biblical themes Manger's Itzik's Midrash and Songs of the Megillah deserve special mention, as they represent his first attempts to re-write old, familiar material through a modernist lens. In Itzik's Midrash, Manger presents a modern commentary on the classic Bible stories by anachronistically placing his characters in contemporary Eastern Europe. Manger's playful attitude towards the original text is self-evident; in the introduction he writes, "As I wrote this book, the rogue's cap of the Yiddish Purim play hovered always before my eyes." Inspired by the Purimshpiel genre, which used a traditional story to mock the norms and expectations of Jewish religious life in previous centuries, Manger's Midrash radically revises traditional portrayals of Biblical characters by requiring them to justify their actions according to modern norms and values. Traditionally valued characters such as Abraham and Sarah are harshly critiqued, while under-represented characters like Hagar and Ishmael are given a voice. In Songs of the Megillah, Manger uses a similar technique to politicise and de-sacralize the Biblical text read aloud

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.
