请专业人士来判断一下,此英文句子是复合句还是简单句
Having endured a miserably negative campaign,the world’s most powerful country now has a much more difficult decision to make than it faced four years ago.
"it faced"有主语和谓语,算不算一个independent clause?
答
Having endured a miserably negative campaign(状语）, the world’s most powerful country （主语）now has a much more difficult decision to make than（which 定语从句一引导词which省略） it faced four years ago.所以是复合句.
