OG240关于形容词的用法

240. What brought the automobile company back from the verge of bankruptcy shortly after the Second World War was a special, governmentally sanctioned price increase allowed during a period of wage and price controls.

红线部分sanctionaed和allowed是同义词,为什么会用在一个句子里修饰同一个词??

没有NN进来回答啊?顶一下.

governmentally sanctioned price increase  +

the price increase was allowed during a period of wage and price controls

政府管制下的调升价格，但是这次价格上涨是仅在特殊时期允许的。
