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>
in the 55th minute, as Arsenal fell to a 5–1 defeat. January Arsenal started 2019 with a 4–1 victory against relegation contenders Fulham. Granit Xhaka, Alexandre Lacazette, Aaron Ramsey, and Pierre-Emerick Aubameyang scored for the Gunners; Aboubakar Kamara scored for the visitors. Arsenal kicked off their FA Cup campaign away to Blackpool. Joe Willock scored a brace and Alex Iwobi added another en route to a 3–0 victory. Arsenal lost again away in the league, Declan Rice's goal was enough for West Ham to snatch the 3 points at London Stadium. However, the Gunners responded in their next match, a 2–0 victory against rivals Chelsea at Emirates Stadium courtesy of Alexandre Lacazette and Laurent Koscielny goals took Arsenal within 3 points of the opponent. Despite the victory, the Gunners took a massive blow, as Hector Bellerín tore his anterior cruciate ligament, ruling him out for the rest of the season. Next up was an FA Cup match against in-form rivals Manchester United. Alexis Sánchez scored for United against his former side. It was quickly made 2–0 in favor of the away team through Jesse Lingard. Pierre-Emerick Aubameyang halved the deficit just before the break, however Anthony Martial wrapped up the victory for United as Gunners were eliminated, losing 3–1. Arsenal's final game in January came at home to Cardiff City, who were playing their first match since the death of Emiliano Sala. Aubameyang scored the first goal of the game, slotting his penalty home. Lacazette doubled the advantage after making a brilliant run into the box. Nathaniel Mendez-Laing scored a stoppage-time consolation for Cardiff. The victory sent Arsenal up to 4th place over Chelsea. February Arsenal's first match of February was a tough one, away to title contenders and defending champions Manchester City. Sergio Agüero scored for City in the 1st minute of the match. However, the Gunners responded, Laurent Koscielny nodded home from close range in the 10th minute. Agüero scored his second just before the break, and City extended their lead to 3–1 with a controversial goal from Agüero, thus sealing his hat trick. Arsenal faced relegation-threatened Huddersfield away from home. Alex Iwobi scored first, before Lacazette doubled the advantage. Huddersfield scored a last-minute consolation, Sead Kolašinac scoring an own goal. After more than two months away from Europe, the Gunners were back in Europa League action via a trip to Barysaw to face Belarusian minnows BATE Borisov. However, a lacklustre display ensued, and Stanislaw Drahuns header on the stroke of half time, coupled with Alexandre Lacazette's late red card, saw BATE record a famous 1–0 win and an advantage to take to North London. However, the second leg had a fairly varying script to the first game, with defensive errors from BATE ultimately gifting Arsenal a 3–0 win, after an early own goal from Zakhar Volkov, coupled with free headers from Shkodran Mustafi and Sokratis Papastathopolous-the Greeks first goal for the club- guided Arsenal into the last-16. The Gunners built on the victory with a routine 2–0 home win over Southampton, earned after early goals from Lacazette and Henrikh Mkhitaryan. The Arsenal faithful then witnessed yet another Emirates Stadium win, with midfield masterclasses from Mkhitaryan and returning Mesut Özil setting up a 5–1 dismantling of Bournemouth. Both Özil and Mkhitaryan scored, with the latter setting up goals from Laurent Koscielny and Pierre-Emerick Aubameyang, whilst Lacazette was on the scoresheet for the third successive league match, bending home a wonderful free-kick with 12 minutes to play. March A testing March fixture schedule opened with a daunting trip to top-four rivals Tottenham Hotspur. Delays in the construction of Spurs

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.
