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>
by 1840. Tomago House retains the core of a once larger rural estate, with its sweeping entrance carriage drives off Tomago Road approaching the house from the north-west, and another drive towards the chapel to the west. The drive is lined with jacarandas (Jacaranda mimosifolia), an evergreen magnolia / bull bay (M.grandiflora) and lemon-scented gums (Corymbia citriodora). The grounds are fairly thickly planted with mature coniferous trees reflecting the fashion for pineta or conifer collections in the 19th century – these comprise predominantly exotic pine species including Mediterranean stone pine (Pinus pinea), Monterey pine (California: Pinus radiata), Bunya pine (Queensland: Araucaria bidwillii), Norfolk Island pine (Araucaria heterophylla) and hoop pine trees (Northern NSW/ Queensland: Araucaria cunninghamii). Other major trees include a number of large old Moreton Bay figs (Ficus macrophylla), locally-native turpentines (Syncarpia glomulifera), 20th-century plantings of jacarandas (Jacaranda mimosifolia), Qld. lemon-scented gums (Corymbia citriodora) on both carriage loops and a large 19th-century mature bull bay / evergreen or Southern magnolia (M.grandiflora) south of the house towards the river terrace. Another unusual tree here is the South African Cape chestnut (Cupania capensis), north of the house. Large clumps of Mauritius hemp (Furcraea selloa) remain underneath the trees north of the house. Two large clumps of giant bamboo (Bambusa balcooa) are on the terrace south of the house and in the ephemeral lagoon area to the south, in the vicinity of the (lost) pleasure garden there. A solitary date palm (Phoenix dactylifera) is north-west of the house on the grass terrace and several tall old specimens of locally-native cabbage palms (Livistona australis) remain in the lagoon area south of the house, probably predating it. A number of Qld. silky oaks (Grevillea robusta), Northern-NSW/Qld. brush box (Lophostemon confertus), locally-native red ash (Alphitonia excelsa), American sweet gum (Liquidambar styraciflua) trees are also in the grounds. Near the front door of the house on the northern side a large orchid tree (Bauhinia variegata cv.) is covered with staghorn ferns. Other native species include smooth-barked apple/Sydney red gum (Angophora costata), native peach (Breynia oblongifolia), Qld. lacebark (Brachychiton discolor), Qld. black bean/native chestnut (Castanospermum australe); tuckeroo (Cupaniopsis anacardioides); corkwood (Endiandra sieberi); bangalay (Eucalyptus botryoides); W.A. yellow bloodwood (Corymbia eximia); flooded gum (E.grandis); tallowood (E.microcorys); blackbutt (E.pilularis); white mahogany (E. spp. (?E.acmenioides)); cheese tree (Glochidion ferdinandi); broad-leaved paperbark (Melaleuca quinquenervia); white cedar (Melia azedarach); tree broom/heath (Monotoca elliptica); Qld./N.NSW firewheel tree (Stenocarpus sinuatus); magenta lily pilly (Syzygium paniculatum); red cedar (Toona ciliata) and woody pear (Xylomelum pyriforme); Darling or river lily (Crinum sp.); she oak (Casuarina sp.). Other exotic species include Cape chestnut (Calodendrum capense); Atlas cedar (Cedrus atlantica); camphor laurel (Cinnamomum camphora); Monterey cypress (Hesperocyparis macrocarpa); cockspur coral tree (Erythrina crista-galli); crepe myrtle (Lagerstroemia indica cv.); Hupeh crab apple (Malus hupehensis); oleander (Nerium oleander cv.); avocado (Persea americana cv.); Mexican weeping pine (Pinus patula); Eastern cottonwood (Populus deltoides), Lombardy poplar (P.nigra 'Italica'); plum (Prunus domestica cv.); peach (P.persica cv.); pear (Pyrus communis cv.); cherry guava (Psidium cattleyanum); tree gardenia (Rothmannia globosa); pepper tree (Schinus molle); Camellia japonica cv. shrubs; autumn camellias (Camellia sasanqua cv.s); oranges (Citrus sinensis cv.); Hibiscus spp.; French lavender (Lavandula dentata); Cocos Island palm (Syagrus romanzoffiana); star jasmine (Trachelospermum jasminoides); laurustinus (Viburnum tinus); London or hybrid plane (Platanus x acerifolia); and Chinese wisteria (Wisteria sinensis). Other structures The estate included a range of outbuildings comprising a gatehouse, stables and dairy. A Chapel was added in 1860-1861 west of the house in paddock surroundings. A caretaker's cottage was added between 1850s-1880s - originally two storeys, in brick. This was reduced to a single storey cottage in the 1950s. House Built by barrister Richard Windeyer,

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.
