Question

This kind of paper as soft and light as silk but ___ expensi

Answer 1

1.less expensive 表示更便宜,所以b little没有更得意思.little的比较及是less;c 纸是不可数名词,用much修饰,不能用many；d,more expensive than sth,而不是more than expensive

2.a和c意思相左.

prevent sb from doing sth阻止某人做某事

prevent sth to do sth.阻止某事,以做某事/达某目的.

这2个是习惯搭配.b 和d 语法不对.
