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>
Asia 70,000, 30,000 interned non-Asian civilians; Timor 60,000; Thailand and Pacific Islands 60,000. Gruhl estimates POW deaths in Japanese captivity at 331,584. Detailed by country: China 270,000; Netherlands 8,500; Britain 12,433; Canada 273; Philippines 20,000; Australia 7,412; New Zealand 31; and the United States 12,935. Out of 60,000 Indian Army POWs taken at the Fall of Singapore, 11,000 died in captivity. There were 14,657 deaths among the total 130,895 western civilians interned by the Japanese due to famine and disease. Oppression in the Soviet Union The total war dead in the USSR includes about 1 million victims of Stalin's regime. The number of deaths in the Gulag labor camps increased as a result of wartime overcrowding and food shortages. The Stalin regime deported the entire populations of ethnic minorities considered to be potentially disloyal. Since 1990 Russian scholars have been given access to the Soviet-era archives and have published data on the numbers of people executed and those who died in Gulag labor camps and prisons. The Russian scholar Viktor Zemskov puts the death toll from 1941–1945 at about 1 million based on data from the Soviet archives. The Soviet-era archive figures on the Gulag labor camps has been the subject of a vigorous academic debate outside Russia since their publication in 1991. J. Arch Getty and Stephen G. Wheatcroft maintain that Soviet-era figures more accurately detail the victims of the Gulag labor camp system in the Stalin era. Robert Conquest and Steven Rosefielde have disputed the accuracy of the data from the Soviet archives, maintaining that the demographic data and testimonials by survivors of the Gulag labor camps indicate a higher death toll. Rosefielde posits that the release of the Soviet Archive figures is disinformation generated by the modern KGB. Rosefielde maintains that the data from the Soviet archives is incomplete; for example, he pointed out that the figures do not include the 22,000 victims of the Katyn massacre. Rosefielde's demographic analysis puts the number of excess deaths due to Soviet repression at 2,183,000 in 1939–40 and 5,458,000 from 1941–1945. Michael Haynes and Rumy Husun accept the figures from the Soviet archives as being an accurate tally of Stalin's victims, they maintain that the demographic data depicts an underdeveloped Soviet economy and the losses in World War Two rather than indicating a higher death toll in the Gulag labor camps. In August 2009 the Polish Institute of National Remembrance (IPN) researchers estimated 150,000 Polish citizens were killed due to Soviet repression. Since the collapse of the USSR, Polish scholars have been able to do research in the Soviet archives on Polish losses during the Soviet occupation. Andrzej Paczkowski puts the number of Polish deaths at 90,000–100,000 of the 1.0 million persons deported and 30,000 executed by the Soviets. In 2005 Tadeusz Piotrowski estimated the death toll in Soviet hands at 350,000. The Estonian State Commission for the Examination of Repressive Policies Carried out During the Occupations put civilian deaths due to the Soviet occupation in 1940–1941 at 33,900 including (7,800 deaths) of arrested people, (6,000) deportee deaths, (5,000) evacuee deaths, (1,100) people gone missing and (14,000) conscripted for forced labor. After the reoccupation by the U.S.S.R., 5,000 Estonians died in Soviet prisons during 1944–45. The following is a summary of the data from the Soviet archives: Reported deaths for the years 1939–1945 1,187,783, including: judicial executions 46,350; deaths in Gulag labor camps 718,804; deaths in labor colonies and prisons 422,629. Deported to special settlements: (figures are for deportations to Special Settlements only, not including those executed, sent to Gulag labor camps or conscripted into the Soviet Army. Nor do

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.
