Final answer:
Option C, 'The dietitian has got to improve the food service in the cafeteria,' contains the word choice error due to informality of 'has got to.' A better word choice would be 'The dietitian needs to improve.'
Step-by-step explanation:
The question concerns identifying a sentence with a word choice error. To address it accurately, we should carefully analyze each sentence and determine if they include any inappropriate or incorrect words for the context.
Let's examine the options:
- Option 1: "The sprinter ran as fast as he could." - This sentence is clear and contains no word choice errors.
- Option 2: "The man must deliver the materials to the center by four o'clock." - This is a directive sentence with correct word usage.
- Option 3: "The dietitian has got to improve the food service in the cafeteria." - The word "got" is often considered informal and might be viewed as unnecessary or less professional in this context. A more formal alternative would be, "The dietitian needs to improve the food service in the cafeteria."
- Option 4: "The chemist is trying to develop a new fertilizer." - This sentence is professionally worded and appropriate for the context.
Among these options, option C is the most likely to be flagged for a word choice error due to the informal nature of the phrase "has got to." It is important to consider the register and formality of language when discerning word choice appropriateness.
