Task: Question Generation
Input (English): Passage: A new offer had arrived for Pei from the Chinese government in 1982. With an eye toward the transfer of sovereignty of Hong Kong from the British in 1997, authorities in China sought Pei's aid on a new tower for the local branch of the Bank of China. The Chinese government was preparing for a new wave of engagement with the outside world and sought a tower to represent modernity and economic strength. Given the elder Pei's history with the bank before the Communist takeover, government officials visited the 89-year-old man in New York to gain approval for his son's involvement. Pei then spoke with his father at length about the proposal. Although the architect remained pained by his experience with Fragrant Hill, he agreed to accept the commission.The proposed site in Hong Kong's Central District was less than ideal; a tangle of highways lined it on three sides. The area had also been home to a headquarters for Japanese military police during World War II, and was notorious for prisoner torture. The small parcel of land made a tall tower necessary, and Pei had usually shied away from such projects; in Hong Kong especially, the skyscrapers lacked any real architectural character. Lacking inspiration and unsure of how to approach the building, Pei took a weekend vacation to the family home in Katonah, New York. There he found himself experimenting with a bundle of sticks until he happened upon a cascading sequence.Pei felt that his design for the Bank of China Tower needed to reflect "the aspirations of the Chinese people".  The design that he developed for the skyscraper was not only unique in appearance, but also sound enough to pass the city's rigorous standards for wind-resistance.   The tower was planned around a visible truss structure, which distributed stress to the four corners of the base. Using the reflective glass that had become something of a trademark for him, Pei organized the facade around a series of boxed X shapes. At the top, he designed the roofs at sloping angles to match the rising aesthetic of the building. Some influential advocates of feng shui in Hong Kong and China criticized the design, and Pei and government officials responded with token adjustments.As the tower neared completion, Pei was shocked to witness the government's massacre of unarmed civilians at the Tiananmen Square protests of 1989. He wrote an opinion piece for The New York Times titled "China Won't Ever Be the Same", in which he said that the killings "tore the heart out of a generation that carries the hope for the future of the country". The massacre deeply disturbed his entire family, and he wrote that "China is besmirched.".
Output (English): What paper did the architect submit his opinion on the major event that occurred in Tiananmen Square?
