What is the transformation for "The exam was difficult." using "difficulty"?

The correct response uses "difficulty" to convey the essence of the original statement in a natural and coherent manner. In "There was difficulty with the exam," the transformation effectively captures the challenging nature of the exam while maintaining grammatical correctness and clarity. It implies that the exam posed challenges, aligning with the idea that "The exam was difficult."

The other options, while attempting to utilize "difficulty," do not express the sentiment of the original sentence accurately. For example, stating "The exam has much difficulty" can sound awkward and does not convey the idea that the exam itself was challenging. Similarly, "The difficulty was in the exam" shifts the focus and does not maintain the original statement's intent. Lastly, "There was an exam of difficulty" also sounds unnatural and can be misleading since it introduces a vague construct that doesn't directly relate the exam's difficulty to the experience of the students.
