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>
also prevented the execution of a plan to demolish the Budapest Ghetto with around 60,000 people in it, as the Nazis had done in Warsaw. While Perlasca was posing as the Spanish consul-general, he learned of the intentions of the SS and Arrow Cross to destroy the ghetto. Shocked and incredulous, he asked for a direct hearing with the Hungarian interior minister, Gábor Vajna, and threatened him with legal and economic measures against the "3,000 Hungarian citizens" (in fact, a much smaller number) declared by Perlasca as residents of Spain, unless he withdrew the plan. Perlasca also offered to help Vajna and his family escape from Hungary before the advancing Soviet Army reached Budapest. The plan to raze the Budapest Ghetto was subsequently cancelled. After the war After the war, Perlasca returned to Italy. He did not talk about his actions in Hungary to anyone, including his family, and lived a quiet, humble life. In 1987, a group of Hungarian Jews whom he had saved finally found him after searching for him for 42 years in Spain. There was publicity at the time, and Perlasca became noted for his heroic deeds. Enrico Deaglio wrote an account of his remarkable heroism, Banality of Goodness, (2002), which became a bestseller. The book was adapted as a made-for-TV film, Perlasca – Un eroe Italiano (2005), by the RAI national television corporation. Giorgio Perlasca died of a heart attack in 1992. Decorations and honors In 1987 Perlasca was made an honorary citizen of Israel and was honored by the Yad Vashem Holocaust Memorial Museum with a stele and a 10,000 tree forest. Perlasca was designated by Israel as a Righteous Among the Nations in 1989 for his efforts Star of Merit, Hungary, 1989 Knesset Medal, Israel, 1989 Town Seal of Padova, Italy, 1989 Wallenberg Medal, United States, 1990 Medal of Remembrance of the United States Holocaust Memorial Council, USA, 1990 Invitation to lay the first stone of the Holocaust Museum in Washington, USA, 1990 Knight Grand Cross, Spain, 1991 1st Class, Knight Grand Cross (Italy), 1991 Gold Medal for Civil Bravery (Italy), 1992 A bust of Perlasca was created in Budapest. As part of its Righteous Among the Nations project, the Raanana Symphonette Orchestra commissioned an original orchestral piece, "His Finest Hour", from composer Moshe Zorman in tribute to Perlasca. The piece premiered December 10, 2014 in Raanana in the presence of Perlasca's son Franco and daughter-in-law Luciana Amadia.

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.
