What is a common challenge in the key word transformation task?

The key word transformation task primarily focuses on maintaining the original meaning of a sentence while changing its wording based on a given key word. This involves rephrasing the sentence effectively without altering its essential message, which is a significant challenge. The skill required here includes a deep understanding of synonyms, sentence structure, and nuances in meaning, as even subtle changes can lead to a loss of the original intent.

Successfully navigating this task relies on a student's ability to manipulate language creatively while adhering closely to the original context. For example, transforming "She is too tired to go out" into "She is not energetic enough to go out" demonstrates this skill well. The original meaning of being too fatigued to participate in an activity remains intact, showcasing a successful transformation.

In contrast, the other options either introduce unrelated aspects or challenges. Creating an entirely new idea diverges from the principle of transformation, as it moves away from the original context. Translating from one language to another does not apply because the task is inherently about re-wording within the same language. Finally, using complex vocabulary may enhance expression but is not a requirement of the key word transformation task and does not guarantee the retention of the original meaning.
