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>
composed of a single graphic element (such as shān 山 "mountain"), and the latter being those containing more than one such element (such as hǎo 好 "good" with 女 "woman" and 子 "child") which can be deconstructed into and analyzed in terms of their component elements. Note that the character 文 itself exemplifies the category wén 文, while 字 (which is composed of 宀 and 子) exemplifies zì 字. Thus, Shuōwén Jiězì means "commenting on" (shuō "speak; talk; comment; explain") the wén, which cannot be deconstructed, and "analyzing" (jiě "untie; separate; divide; analyze; explain; deconstruct") the zì. Although the "six principles" of Chinese character classification (liùshū 六書 "six graphs") had been mentioned by earlier authors, Xu Shen's postface was the first work to provide definitions and examples. He uses the first two terms, simple indicatives (zhǐshì 指事) and pictograms (xiàngxíng 象形) to explicitly label character entries in the dictionary, e.g., in the typical pattern of "(character) (definition) ...simple indicative" (A B 也...指事 (也)). Logographs belonging to the third principle, phono-semantic compound characters (xíngshēng 形聲), are implicitly identified through the entry pattern A… from B, phonetically resembles C (A...從 B, C 聲), meaning that element B plays a semantic role in A, while C gives the sound. The fourth type, compound indicatives (huìyì 會意), are sometimes identified by the pattern A...from X from Y (A...從 X 從 Y), meaning that the compound A is given meaning through the graphic combination and interaction of both constituent elements. The last two of the six principles, borrowed characters (aka phonetic loan, jiǎjiè 假借) and derived characters (zhuǎnzhù 轉注), are not identifiable in the character definitions. According to Imre Galambos, the function of the Shuowen was educational. Since Han studies of writing are attested to have begun by pupils of 8 years old, Xu Shen's categorization of characters was proposed to be understood as a mnemonic methodology for juvenile students. Textual history and scholarship Although the original Han dynasty Shuōwén Jiězì text has been lost, it was transmitted through handwritten copies for centuries. The oldest extant trace of it is a six-page manuscript fragment from the Tang dynasty, amounting to about 2% of the entire text. The fragment, now in Japan, concerns the mù (木) section header. The earliest post-Han scholar known to have researched and emended this dictionary, albeit badly, was Lǐ Yángbīng (李陽冰, fl. 765–780), who "is usually regarded as something of a bête noire of [Shuowen] studies," writes Boltz, "owing to his idiosyncratic and somewhat capricious editing of the text." Shuowen scholarship improved greatly during the Southern Tang-Song dynasties and later during the Qing dynasty. The most important Northern Song scholars were the Xú brothers, Xú Xuàn (徐鉉, 916–991) and Xú Kǎi (徐鍇, 920–974). In 986, Emperor Taizong of Song ordered Xú Xuàn and other editors to publish an authoritative edition of the dictionary. This was published as the 説文解字繫傳 Shuowen Jiezi xichuan. Xu Xuan's textual criticism has been especially vital for all subsequent scholarship, since his restoration of the damage done by Lǐ Yángbīng resulted in the closest version we have to the original, and the basis for all later editions. Xu Kai, in turn, focused on exegetical study, analyzing the meaning of Xu Shen's text, appending supplemental characters, and adding fǎnqiè pronunciation glosses for each entry. Among Qing Shuowen scholars, some like Zhū Jùnshēng (朱駿聲, 1788–1858), followed the textual criticism model of Xu Xuan, while others like Guì Fù (桂馥, 1736–1805) and Wáng Yún (王筠, 1784–1834) followed the analytical exegesis model of Xu Kai. One Qing scholar, Duan Yucai, stands above all the others due to the quality of his

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.
