The Frauenkirche in Dresden, a historic church destroyed by bombing in World War II, has been reconstructed to serve as a place for church services and cultural events. The foundation doing the reconstruction took extraordinary care to return the church to its original form. It is a puzzle, then, why the foundation chose not to rebuild the eighteenth-century baroque organ originally designed for the church and instead built a modern organ, even though a donor had offered to pay the full cost of rebuilding the original. Which one of the following, if true, would most help to resolve the puzzle described above? ['An eighteenth-century baroque organ cannot adequately produce much of the organ music now played in church services and concerts.', 'By the time the church was destroyed in World War II, the eighteenth-century baroque organ had been modified several times.', 'The organ originally designed for the church had some features that modern organs lack.', 'The donation for rebuilding the original eighteenth-century baroque organ was designated for that purpose alone.']
