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>
House (season 1) The first season of House premiered November 16, 2004, and ended May 24, 2005. The season followed Dr. House and his team as they solve a medical case each episode. The season's sub-plot revolved around billionaire Edward Vogler making a $100 million donation to the hospital. Through this donation, Vogler became the new chairman of the board of the hospital. Since the beginning, he starts seeing House and his team as a waste of time and resources. Vogler also resents the fact that House seems not to be answering to anyone, so he keeps putting increasing pressure on House to fire one of his team members. Vogler does this to show House he can control him: "I need to know that whatever I ask you to do, however distasteful you find it, you'll do it". Chi McBride joined the cast as Vogler in five episodes of the season. His character was brought in after Universal Studios president Jeff Zucker threatened that the season would be cut short by six episodes if a "boss" character wasn't added. While there were possibilities of the character returning, he was generally disliked by viewers and critics and therefore not brought back into the show. Sela Ward, who would return as the main recurring character of season two, appeared in the final two episodes as Stacy Warner, House's former girlfriend. Cast and characters Main cast Hugh Laurie as Dr. Gregory House Lisa Edelstein as Dr. Lisa Cuddy Omar Epps as Dr. Eric Foreman Robert Sean Leonard as Dr. James Wilson Jennifer Morrison as Dr. Allison Cameron Jesse Spencer as Dr. Robert Chase Recurring cast Chi McBride as Edward Vogler Sela Ward as Stacy Warner Stephanie Venditto as Nurse Brenda Previn Kenneth Choi as Dr. Lim Ron Perkins as Dr. Ron Simpson Currie Graham as Mark Warner Maurice Godin as Dr. Lawrence Hourani Guest cast Andrew Airlie, John Patrick Amedori, Skye McCole Bartusiak, Patrick Bauchau, Nicole Bilderback, Brandy, Hedy Burress, Nestor Carbonell, Ever Carradine, John Cho, Sarah Clarke, David Conrad, Christina Cox, Missy Crider, Myndy Crist, Nicholas D'Agosto, Ann Dowd, Stacy Edwards, Carmen Electra, Cynthia Ettinger, Scott Foley, Erin Foster, Kurt Fuller, Wendy Gazalle, Michael A.

Reception Season one gained high Nielsen ratings, averaging 13.3 million viewers an episode. It was 24th most-watched television show of the 2004–2005 television season. Hugh Laurie submitted the episode "Detox" for consideration of his work for the 57th Primetime Emmy Awards in 2005. This resulted in his first Emmy Award nomination for Outstanding Lead Actor in a Drama Series for his role as Dr. Gregory House. Episodes Home media The Region 1 DVD set of Season 1 was issued in non-anamorphic widescreen (meaning those with widescreen TVs would have to use the Zoom button for the show to fit their screen properly, causing the picture to be blurry) on 3 double-sided discs. However, Universal reissued the Season 1 set on February 10, 2009 in the correct anamorphic widescreen aspect ratio, which is now on 6 single-sided discs instead of the 3 double-sided ones.

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.

8. Final check:
  a. Review the Updated_Passage to ensure all PIs and KFIs are properly tagged.
  b. Verify that the first PI in the passage starts with <|start-PI|>.
  c. Make sure there are no missing or misplaced tags.
 
Remember to analyze the entire passage, identify all relevant PI-KFI pairs, and provide the output for each pair as specified. After completing the analysis, present the original passage with the <|retrieval|> tokens inserted in their appropriate positions as part of a new key in the JSON file. Only Ouput the JSON File.
