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>
Théodore Chassériau Théodore Chassériau (September 20, 1819 – October 8, 1856) was a Dominican-born French Romantic painter noted for his portraits, historical and religious paintings, allegorical murals, and Orientalist images inspired by his travels to Algeria. Early in his career he painted in a Neoclassical style close to that of his teacher Jean-Auguste-Dominique Ingres, but in his later works he was strongly influenced by the Romantic style of Eugène Delacroix. He was a prolific draftsman, and made a suite of prints to illustrate Shakespeare's Othello. Life and work Chassériau was born in El Limón, Samaná, in the Spanish colony of Santo Domingo (now the Dominican Republic). His father Benoît Chassériau was a French adventurer who had arrived in Santo Domingo in 1802 to take an administrative position in what was until 1808 a French colony. Theodore's mother, Maria Magdalena Couret de la Blagniére, was the daughter of a mulatto landowner born in Saint-Domingue (now Haiti). In December 1820 the family left Santo Domingo for Paris, where the young Chassériau soon showed precocious drawing skill. He was accepted into the studio of Jean-Auguste-Dominique Ingres in 1830, at the age of eleven, and became the favorite pupil of the great classicist, who regarded him as his truest disciple. (An account that may be apocryphal has Ingres declaring "Come, gentlemen, come see, this child will be the Napoleon of painting.") After Ingres left Paris in 1834 to become director of the French Academy in Rome, Chassériau fell under the influence of Eugène Delacroix, whose brand of painterly colorism was anathema to Ingres. Chassériau's art has often been characterized as an attempt to reconcile the classicism of Ingres with the romanticism of Delacroix. He first exhibited at the Paris Salon in 1836, and was awarded a third-place medal in the category of history painting. In 1840 Chassériau travelled to Rome and met with Ingres, whose bitterness at the direction his student's work was taking led to a decisive break. While in Italy, Chassériau made landscape sketches and studied Renaissance frescoes. Among the chief works of his early maturity are Susanna and the Elders and Venus Anadyomene (both 1839), Diana Surprised by Actaeon (1840), Andromeda Chained to the Rock by the Nereids (1840), and The Toilette of Esther (1841), all of which reveal a very personal ideal in depicting the female nude. Chassériau's major religious paintings from these years, Christ on the Mount of Olives (a subject he treated in 1840 and again in 1844) and The Descent from the Cross (1842), received mixed reviews from the critics; among the artist's champions was Théophile Gautier. In 1843, Chassériau painted murals depicting the life of Saint Mary of Egypt in the Church of Saint-Merri in Paris, the first of several commissions he received to decorate public buildings in Paris. Portraits from this period include the Portrait of the Reverend Father Dominique Lacordaire, of the Order of the Predicant Friars (1840), and The Two Sisters (1843), which depicts Chassériau's sisters Adèle and Aline. Throughout his life he was a prolific draftsman; his many portrait drawings executed with a finely pointed graphite pencil are close in style to those of Ingres. He also created a body of 29 prints, including a group of eighteen etchings of subjects from Shakespeare's Othello in 1844. He exhibited the colossal portrait Ali-Ben-Hamet, Caliph of Constantine and Chief of the Haractas, Followed by his Escort in the Salon of 1845, where it received equivocal reviews. In 1846, Chassériau made his first trip to Algeria. From sketches made on this and subsequent trips he painted such subjects as Arab Chiefs Visiting Their Vassals and

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.
