Explain what leads to ambiguity in the sentence He is a hard businessman.
【正确答案】：The word hard in this context can mean both “hardworking^ and "difficult” The context fails to narrow down the meaning so that it is difficult for the reader to decide what exactly the speaker means. When a word with multiple meanings is used in inadequate context, it creates ambiguity.
