New Question
To ensure the accuracy of the statistical model, the engineers double-checked the data pre-processing steps before training the model. The training data had already been cleaned ___ the consulting team's specifications.
A. of B. by C. with D. to
Explanation: "by" indicates the agent (who/what did the action) in a passive sentence.
of: The complexity of the algorithm is high.
by: The code was debugged by the lead engineer.
with: We simulated the data with a new method.
to: The model's output must conform to the parameters.
Answer: B
Analysis of the Request and Template Compliance
The user wants a TOEIC-style multiple-choice question following a strict, compressed template. The question must focus on a clear grammar point and all example sentences must be minimal (max 10 words) and relate to specific technical fields: machine learning, consulting, applied math, statistics, or engineering.
The user provided an example and then asked to "recreate this prompt" using "terms from applied mathematics, statistical mathematics, and machine learning mathematics" in the examples. This means the output should be a new question set that adheres to all the original rules and the enhanced thematic constraint for the examples.
Grammar Point Selection
I will choose a preposition question, as it's common in TOEIC, and the template forces a very specific context.
Template Compliance Check
- [Question sentence with blank]: The training data had already been cleaned ___ the consulting team's specifications. (Grammar point: Preposition after a passive structure, specifically "cleaned by X" or "cleaned to X" or "cleaned according to X." I will use an option that is contextually correct but not the only one, forcing a choice.)
- A. choice1 B. choice2 C. choice3 D. choice4: A. of B. by C. with D. to
- Explanation: “by” indicates the agent (who/what did the action) in a passive sentence. (Short and clear.)
- choiceX: [example sentence]:
- Must be max 10 words. (Will ensure compliance.)
- Must relate to the specified fields. (Will use terms like algorithm, debugged, simulated, method, output, parameters.)
- Must show the function of the preposition. (Will ensure compliance.)
- Answer: [correct choice]: B
Self-Correction on the Question Sentence: While "cleaned to specifications" is grammatically and contextually sound, the most common structure to test the agent in a passive structure is by. I'll change the context slightly to make "by" the clearer correct answer for the specific grammar point of an agent in a passive voice.
Revised Question and Explanation: I will stick to the original plan of preposition, as it is well-suited for a quick-fire TOEIC question. I will change the sentence structure to better facilitate "by" as the agent.
Wait, the original sentence: The training data had already been cleaned ___ the consulting team's specifications. - cleaned to specifications \rightarrow common, means in accordance with.
- cleaned by the consulting team \rightarrow common, means done by the agent.
Since the question asks the data was cleaned ___ the consulting team's specifications, "to" is very strong (cleaned to a standard). However, "by" is the choice I made to represent the agent's action. I will slightly reword the question to make "by" the clear answer for the passive agent grammar point, as that is a very common TOEIC test point.
New Question Attempt focusing on Agent:
The statistical model was implemented ___ the lead engineer.
A. of B. by C. with D. to
Explanation: "by" indicates the agent (who/what did the action) in a passive sentence.
This works perfectly for the grammar point. I will now create the full set.The statistical model was implemented ___ the lead engineer on the project.
A. of B. by C. with D. to
Explanation: "by" indicates the agent (who/what did the action) in a passive sentence.
of: The complexity of the algorithm is high.
by: The system was debugged by the lead engineer.
with: We simulated the data with a new regression method.
to: The model's output must conform to the parameters.
Answer: B
