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>
the scientific idea he pursues. He does not hear the cries of the animals, he does not see their flowing blood, he sees nothing but his idea ..." Walter Gratzer, professor emeritus of biochemistry at King's College London, writes that significant opposition to vivisection emerged in Victorian England, in part in revulsion at the research being conducted in France. Bernard and other well-known physiologists, such as Charles Richet in France and Michael Foster in England, were strongly criticized for their work. British anti-vivisectionists infiltrated the lectures in Paris of François Magendie, Bernard's teacher, who dissected dogs without anaesthesia, allegedly shouting at them — "Tais-toi, pauvre bête!" (Shut up, you poor beast!) — while he worked. Bernard's wife, Marie-Francoise Bernard, was violently opposed to his research, though she was financing it through her dowry. In the end, she divorced him and set up an anti-vivisection society. This was the atmosphere in the faculty of medicine and the teaching hospitals in Paris when Kingsford arrived, shouldering the additional burden of being a woman. Although women were allowed to study medicine in France, Rudacille writes that they were not welcomed. Kingsford wrote to her husband in 1874: Kingsford was distraught over the sights and sounds of the animal experiments she saw. She wrote on 20 August 1879: Death Alan Pert, one of her biographers, wrote that Kingsford was caught in torrential rain in Paris in November 1886 on her way to the laboratory of Louis Pasteur, one of the most prominent vivisectionists of the period. She reportedly spent hours in wet clothing and developed pneumonia, then pulmonary tuberculosis.<ref name=PertLastYears>Pert, Alan.

In July 1887, she settled in London in a house she and her husband rented at 15 Wynnstay Gardens, Kensington, and waited to die, although she remained mentally active. She died on 22 February 1888, aged 41, and was buried in the churchyard of Saint Eata's, an 11th-century church in Atcham by the River Severn, her husband's church.

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.
