| Blocks of "high-rise" flats have been
built in large numbers in London and in many other big cities. Just after the
Second World War these big, twenty-to-thirty storey buildings, hundreds of feet
in height, were thought to be the ideal solution to the housing problem. For on
the one hand, there was severe housing shortage, but on the other hand, there
was lack of space to build houses in urban areas. Blocks of "high-rise" flats
seemed at first to be able to solve the problem, since they can offer more
families to live in on less land. The beautiful, modem apartments in the
high-rises were much sought after by people who lived downtown. Hundreds of the vast blocks had been built before anyone began to doubt about whether they were good solutions or not. Are they suitable places for people, children especially, to live in A we A. there was severe house shortage in big cities B. there was less and less land to build houses in big cities C. they were modern and beautiful and much sought after by city people D. they were built on less land and were able to house a lot more people [单选题]氨基酸与糖加热发生美拉德反应，是各种肉类香气的来源。除了烧烤和油炸，红烧大概是最能让美拉德反应发生的“低温烹饪”了。之所以红烧里脊不正宗、一定要红烧肥肉或者五花肉，是因为脂肪在美拉德反应中并非只是打酱油，而是重要参与者。分子美食学创始人蒂斯经过探讨，发现主要是脂肪中的磷脂容易发生氧化，而其产物在纷繁复杂的美拉德反应产物中占据了重要的一席之地。于是，在完全不懂化学、生物的时代，老祖宗们琢磨出的红烧肥肉又一次被后世的科学证实了其合理性。
对以上这段文字理解正确的一项是：
