If the original query is inferring knowledge about the current year, insert the current year into the refined prompt. Generally, if the original query is inferring knowledge about something that happened recently, insert the current month into the refined query. Avoid inserting a day, month, or year for queries that purely ask about facts and about things that don't have much time-relevance. The current date is {str(datetime.now().date())}. Do not insert the current date if not neccessary. Respond with only the refined query for the original query. Don’t use punctuation or quotation marks.\n\nExamples:\n---\nOriginal Query: ‘Who is Harald Baldr?’\nRefined Query: ‘Harald Baldr biography’\n---\nOriginal Query: ‘What happened today with the Ohio train derailment?’\nRefined Query: ‘Ohio train derailment details {str(datetime.now().date())}’\n---\nOriginal Query: ‘Is copper in drinking water bad for you?’\nRefined Query: ‘copper in drinking water adverse effects’\n---\nOriginal Query: What's the current time in Mississauga?\nRefined Query: current time Mississauga\nNow, refine the user input query.\nOriginal Query: {query}\nRefined Query:"

The scheme covers all crops for which past yield data is available, and risk coverage includes yield losses, prevented sowing, post-harvest losses, and localized calamities. It also offers coverage for personal assets of the farmer, such as dwellings and its contents, and other assets that help the farmer earn a livelihood, such as agricultural pump sets and tractors. The scheme includes seven sections, with crop insurance being mandatory, and the farmer's share of the premium ranges from to 5%. It also includes a Weather Based Crop Insurance Scheme, a Unified Package Insurance Scheme, and a centralized repository. In addition, it offers personal accident insurance, student safety insurance, and life insurance.")

The RWBCIS includes operational guidelines and administrative approval issued by the Department of Agriculture, Cooperation and Farmers Welfare (DAC & FW) and the State Government. The CPIS includes operational guidelines issued by the DAC & FW. The scheme covers food crops (cereals, millets, and pulses), oilseeds, and commercial/horticultural crops. The risk period for the scheme is from sowing period to maturity of the crop and is notified by the State Level Crop Cutting and Insurance Committee (SLCCCI). The scheme requires notification from the State/UT Government, which must include details of crops and reference unit areas, applicable sum insured, premium rates, and subsidy. Claims are assessed based on weather data recorded by the notified Reference Weather Stations (RWS) or Back-up Weather Stations (BWS). The scheme also includes a Term Sheet, which outlines the cover phases, strike and exit values, standard loss rates, and policy limits.")

Eligibility for the scheme includes savings bank account holders aged between 18 and 50 years, with an assurance of Rs. 2,00,000 on death of the insured member. The policy provides comprehensive cover for agriculture tractors of up to 10 years and 45 HP, and third party cover with no age limit. In the event of damage, farmers must intimate the insurance company within 48 hours and submit the claim form and other relevant documents within 15 days of the survey. The policy excludes any accidental loss or damage outside the geographical area, any claim arising out of any contractual liability, and any loss or damage caused by depreciation or wear and tear.")
