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>
Alexander Murison A. F. Murison, MA, LLD, KC. (3 March 1847 – 8 June 1934) was an eminent Professor of Roman Law and Jurisprudence at University College, London and at Oxford University. He was a prolific writer for newspapers and journals in a wide variety of subjects with comparatively few publications in his specialism of Roman Law. He collated the text of Theophilus' Greek of Justinian's Institutes but failed to finish his extensive work in this field. However, his translation of Theophilus was published in 2010 as the parallel English text accompanying the Greek in the new edition. He also wrote two biographical works in Scottish history: Sir William Wallace (1898) and King Robert the Bruce (1899) in the Famous Scots Series published by Oliphant, Anderson and Ferrier. Lack of money took him into journalism and he was editor of the Educational Times (now the Times Educational Supplement) from 1902 to 1912 and on the staff of the Daily Chronicle. He even had time to enter politics and he stood as a Liberal Party candidate in at least three General Elections: for the Glasgow and Aberdeen Universities constituency in 1906 and for the Glasgow Central constituency in December 1910 and January 1910 and lost on all three occasions to a Conservative candidate. He died on 8 June 1934 at his home in Clapham Common, London. Origins in Scotland Murison was born at New Deer, Aberdeenshire, Scotland on 3 March 1847. He was born to a crofting family and looked after cattle as a boy. He won a bursary to Aberdeen Grammar School where he excelled and won a scholarship to Aberdeen University. After achieving a first class honours M.A. degree in classics, he returned to his old school and was an English Master there from 1869 to 1876. He married Elizabeth Logan in 1870 and they had two children, Alexander Logan (1871) and James William (1872). William (as he preferred to be called) became Chief Justice of the Straits Settlements. Academic career in London and Oxford 1876–81: Moved to London in 1876 and enrolled as trainee barrister in the Middle Temple and was called to the bar in 1881. 1881–83: Earned his living as a teacher, journalist, and legal practice before the Privy Council and the Chancery Division. 1883–1925: Professor of Roman Law and later of Jurisprudence at University College, London. 1912–24: Dean of the Faculty of Laws and member of the senate of the University of London. Also, in 1915, he became deputy reader in Roman Law at Oxford and then deputy professor of civil law in 1916. 1925–34: Years of retirement and journalism.

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.
