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>
benefit pension, health insurance, professional development reimbursement, 5 paid days bereavement leave, 2 paid personal days, 10 paid sick days, life insurance and other benefits. East Pennsboro teachers' contribution to their health insurance is among the lowest in the midstate, with family plan deductions about $23 every two weeks, with no deductibles and a $20 office co-pay. According to Rep. Glen Grell, a trustee of the state teacher retirement fund, a 40-year educator can retire with a pension equal to 100 percent of their final salary. In 2007, East Pennsboro Area School District employed 206 teachers. The average teacher salary in the district was $48,857 for 181 days worked. The school day is 6.16 hours in length. As of 2007, Pennsylvania ranked in the top 10 states in average teacher salaries. When adjusted for cost of living Pennsylvania ranked fourth in the nation for teacher compensation. In 2010, the costs of the PSERS employee pensions payment was $942,331. This cost rose to $1,867,685 for 2012-13. The cost was $2,136,000 for 2013-14. In 2014, the payment will be $1,249,712 for PSERS and $539,375 to social security. The East Pennsboro Area School District administrative costs per pupil in 2008 were $665.67 per pupil. The lowest administrative cost per pupil in Pennsylvania was $398 per pupil. In 2011, the administration agreed to a one-year pay freeze. The Pennsylvania School Boards Association keeps statistics on salaries of public school district employees in Pennsylvania. According to the association's report, the average salary for a superintendent for the 2007-08 school year was $122,165. Superintendents and administrators receive a benefit package commensurate with that offered to the district's teachers' union. Reserves In 2008, East Pennsboro Area School District reported an unreserved designated fund balance of zero and an unreserved-undesignated fund balance of $1,026,680. In 2010, East Pennsboro Area Administration reported an increase to $4,739,716 in the unreserved-undesignated fund balance. Unreserved designated fund had $424,476. In 2012, the Administration reported that the District had $6,947,414 in total in reserves, with $2,717,826 held in an unreserved account. Pennsylvania school district reserve funds are divided into two categories – designated and undesignated. The undesignated funds are not committed to any planned project. Designated funds and any other funds, such as capital reserves, are allocated to specific projects. School districts are required by state law to keep 5 percent of their annual spending in the undesignated reserve funds to preserve bond ratings. By law the state limits the total unreserved-undesignated fund balance at 8% of the annual budget for school districts that have budgets over $19 million a year. According to the Pennsylvania Department of Education, from 2003 to 2010, as a whole, Pennsylvania school districts amassed nearly $3 billion in reserved funds.

Realignment of program In May 2011, the East Pennsboro Area School Board voted to eliminate several programs, including fourth grade band, middle school Spanish instruction and an elementary school computer program. The cuts eliminated four teacher positions. The cuts were necessitated by a $1.2 million budget deficit for 2011-12. The board

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.
