In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.

[Q]: Whole life insurance, or whole of life assurance (in the Commonwealth of Nations), sometimes called 'straight life' or 'ordinary life,' is a life insurance policy which is guaranteed to remain in force for the insured's entire lifetime, provided required premiums are paid, or to the maturity date. As a life insurance policy it represents a contract between the insured and insurer that as long as the contract terms are met, the insurer will pay the death benefit of the policy to the policy's beneficiaries when the insured dies. Because whole life policies are guaranteed to remain in force as long as the required premiums are paid, the premiums are typically much higher than those of term life insurance where the premium is fixed only for a limited term. Whole life premiums are fixed, based on the age of issue, and usually do not increase with age. The insured party normally pays premiums until death, except for limited pay policies which may be paid-up in 10 years, 20 years, or at age 65. Whole life insurance belongs to the cash value category of life insurance, which also includes universal life, variable life, and endowment policies.
[A]: how frequently does the premium for a whole life policy change during the insured's life

[Q]: The core is the only region in the Sun that produces an appreciable amount of thermal energy through fusion; 99% of the power is generated within 24% of the Sun's radius, and by 30% of the radius, fusion has stopped nearly entirely. The remainder of the Sun is heated by this energy as it is transferred outwards through many successive layers, finally to the solar photosphere where it escapes into space as sunlight or the kinetic energy of particles.
[A]: the long term source of energy that powers the sun is

[Q]: Ancient civilizations required fairly accurate computed values for for practical reasons, including the Egyptians and Babylonians. Around 250 BC the Greek mathematician Archimedes created an algorithm for calculating it. It was approximated to seven digits, using geometrical techniques, in Chinese mathematics, and to about five digits in Indian mathematics in the 5th century AD. The historically first exact formula for , based on infinite series, was not available until a millennium later, when in the 14th century the Madhava -- Leibniz series was discovered in Indian mathematics. In the 20th and 21st centuries, mathematicians and computer scientists discovered new approaches that, when combined with increasing computational power, extended the decimal representation of to many trillions of digits after the decimal point. Practically all scientific applications require no more than a few hundred digits of , and many substantially fewer, so the primary motivation for these computations is the quest to find more efficient algorithms for calculating lengthy numeric series, as well as the desire to break records. The extensive calculations involved have also been used to test supercomputers and high-precision multiplication algorithms.
