Step-by-step explanation
An ambiguous sentence is a series of words that can express two different ideas based on the context that is applied to it. According to the above, the sentence "I could not sleep because of the cricket" is an ambiguous sentence because it can have two interpretations depending on the context. One interpretation is that it refers to the fact the speaker could not sleep because of the sound of the animal "cricket" and another interpretation is that he could not sleep because he was watching a cricket game (sport).
