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>
Thelma Hill Thelma Hill (born Thelma Floy Hillerman; December 12, 1906 – May 11, 1938) was an American silent screen comedian and one of the Sennett Bathing Beauties. Early life and career Born Thelma Floy Hillerman in Emporia, Kansas, she was one of the few Sennett Bathing Beauties to make it into featured roles. Hill was widely known as the "mah jongg bathing girl" because of the mah jongg bathing suit she was photographed in. When she was a child her parents divorced and her father died. Thelma and her mother moved to California where they opened a cafe down the road from the Sennett studios. She was discovered by Roscoe Fatty Arbuckle when she was serving him and dropped soup in his lap. Arbuckle introduced her to Mack Sennett who made her one of his bathing beauties. In a 1924 article Sennett declared she was the "ideal bathing beauty of her time".. The petite actress was just five feet tall and weighed only 100 pounds. She started working as an extra at the Sennett studios in 1919 and appeared in dozens of comedy shorts including Picking Peaches (1924) and The Hollywood Kid (1925). She was a talented comedienne and quickly moved on to featured roles. Hill starred opposite Ben Turpin in A Prodigal Bridegroom (1926) and with Billy Bevan in Hoboken From Hollywood. Mack Sennett saw her potential signed to her a long term long contract. As she became older, Hill began to double for Mabel Normand. From 1927 to 1929, she co-starred with Bud Duncan in Larry Darmour's series of silent Toots and Casper comedy shorts and was Laurel and Hardy's leading lady in Two Tars (1928). She was under contract at FBO in 1927 and was signed by MGM for a role in The Fair Co-Ed (1927). She appeared in a handful of talkies including The Old Barn (1929) and The Naughty Flirt (1931) with Alice White. Her final role was in the Hal Roach comedy Mixed Nuts (1934). Personal life Thelma's parents were married in Salt Lake City, Utah in 1899. They relocated to Emporia, Kansas before Thelma was born and divorced when she was a baby. Her mother Augusta "Gussie" Hillerman was given full custody after alleging her father, railroad worker Clifford Hillerman, had abandoned them for another woman. Clifford Hillerman died in 1914 after suffering an accident at work. Thelma was engaged to director St. Elmo Boyce until he committed suicide in 1930. In 1934 she married John West Sinclair, a stunt man and gag writer for W.C. Fields. By this time Thelma was suffering from alcoholism. Death By 1935 she had retired from movies and was living with her husband at 8229 Blackburn Avenue in Hollywood. Unfortunately she was suffering from depression and alcohol abuse. After having a nervous breakdown she entered Edward Merrill Sanitarium in Culver City, California in early 1938. Her diagnosis was alcoholism, a vitamin deficiency, and malnutrition. She died on May 11, 1938 at the age of 31 from a cerebral hemorrhage. She was buried in Forest Lawn Memorial Park. Although newspapers reported she had a funeral her ashes remain in a storage closet at Forest Lawn's Great Mausoluem. Her widower John West Sinclair would also succumb to alcoholism a few years later.

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.
