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>
Skarżysko-Kamienna Skarżysko-Kamienna is a town in northern Świętokrzyskie Voivodeship in Poland by Kamienna river, to the north of Świętokrzyskie Mountains; one of the voivodship's major towns. Prior to 1928, it bore the name of Kamienna; in less formal contexts usually only the first part of the name (Skarżysko) is used. It belongs to historic Polish province of Lesser Poland. Skarżysko-Kamienna is an important railroad junction, with two main lines (Kraków - Warsaw and Sandomierz - Koluszki) crossing there. History In 1173, the knights' congress gathered in Milica village (now the town's district) led by Casimir II The Just. Around 1885 Kamienna became an important rail junction on the newly built Ivangorod-Dąbrowa Railway. The main line of the railway connecting Ivangorod (Dęblin) and Dąbrowa Górnicza ran through the town from north to south, and two branch lines to Ostrowiec Świętokrzyski and Koluszki radiated from the town east and west, respectively. This spurred the growth of Kamienna from a village into a sizeable town by 1920, when it had about 20 enterprises employing 1000 workers, as well as railway workshops employing an additional 1000 workers. Second Polish Republic In 1923, the commune of Kamienna was granted the status of a town. In 1922 the government of Poland decided to build an ammunition factory in Kamienna, to be called Państwowa Wytwornia Uzbrojenia Fabryka Amunicji (P.W.U. Fabryka Amunicji, "National Armament Factory - Ammunition Plant") It began production in 1924 supplying munitions to the Polish Army. It employed 2760 workers in 1932, over 3000 in 1936, and over 4500 in 1939, becoming the principal employer in the town and driving its growth. The company still functions today under the name Zakłady Metalowe MESKO S.A.). In 1928, town's name was changed to Skarżysko-Kamienna. In 1937 the town had 19,700 inhabitants, among them 2,800 Jews (about 14% of the total). German occupation of Skarżysko-Kamienna (1939-1945) Following the September 1939 invasion of Poland by Germany, Skarżysko-Kamienna was under German occupation until liberated by the Soviet army in January 1945. The Germans controlled the ammunition factory to support their own war effort, and from 1940 it was controlled by the company Hugo Schneider Aktiengesellschaft (HASAG), which ran it as a subcontractor for the Wehrmacht. In 1940, the Germans carried out mass executions of Poles (360 people executed in February and 760 in June). The ghetto for the town's Jewish population was established by the Germans in April or May 1941. Between August 1942 and summer of 1943 Jews from the Radom district were brought to three camps near the munitions factory to work the factory. According to German records, of the total 17,210 brought in with 58 transports, 6,408 managed to survive long enough to be evacuated to other camps when the Germans closed the factory in 1944. The ghetto was liquidated in October 1942, with some inhabitants judged fit for work moved to the factory labour camps (about 500 out of 3000), and the rest were transported to Treblinka. In the major monograph on the subject estimated that despite the incompleteness of German records which likely underestimate the number of inmates, about 25,000 Jewish inmates were brought to the camp and 7,000 were evacuated from it; about 18,000 died there. From 1945 to present On January 18, 1945 the town was liberated. About a dozen Jewish survivors returned to Skarżysko-Kamienna in the winter of 1945-1946 to retrieve Jewish property. Soon afterwards, in February 1946, five of them were murdered for profit by a small group of local criminals. The murderers, among them the head of the Soviet-installed town police and another communist policeman, were put to trial in

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.
