Question: Which was completed first, Manhattan Life Insurance Building or the Singer Building?

<P0-S0> The Supreme Life Building is a historic insurance building located at 3501 S. Dr. Martin Luther King Drive in the Douglas community area of Chicago, Illinois. <P0-S1>  Built in 1921, the building served as the headquarters of the Supreme Life Insurance Company, which was founded two years earlier. <P0-S2>  The company, originally known as the Liberty Life Insurance Company, was the first African-American owned insurance company in the northern United States. <P0-S3>  Since white-owned insurance firms regularly denied black customers life insurance when the firm was founded, the firm played an important role in providing life insurance to Chicago's African-American community. <P0-S4>  The company ultimately became the largest African-American owned business in the northern states and became a symbol of the predominantly black Bronzeville neighborhood's economic success from the 1920s to the 1950s. <SEP> <P1-S0> The Singer Building or Singer Tower, at Liberty Street and Broadway in Lower Manhattan's Financial District, in the U.S. state of New York, was a 47-story office building completed in 1908 as the headquarters of the Singer Manufacturing Company. <P1-S1>  It was the tallest building in the world from 1908 to 1909. <P1-S2>  It was torn down in 1968, together with the adjacent City Investing Building, and is now the site of One Liberty Plaza. <P1-S3>  When it was razed, it became the tallest building ever to be demolished, and is still the third-tallest building ever to be destroyed (after the World Trade Center towers) and the tallest to be purposely demolished by its owner. <SEP> <P2-S0>  It was the first skyscraper to pass 100 m in Manhattan. <P2-S1> The Manhattan Life Insurance Building was a 348 ft tower at 64-66 Broadway in New York City completed in 1894 to the designs of the architects of Kimball & Thompson and slightly extended north in 1904 making its new address 64-70 Broadway. <SEP> <P3-S0> 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. <P3-S1>  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. <P3-S2>  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. <P3-S3>  Whole life premiums are fixed, based on the age of issue, and usually do not increase with age. <P3-S4>  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. <P3-S5>  Whole life insurance belongs to the cash value category of life insurance, which also includes universal life, variable life, and endowment policies.
