Short Answer

Expert verified
C. No one seems certain why

Step by step solution

01

- Understand the Question

The question asks to find the best replacement for the phrase 'No one seems certain of why' without changing the meaning of the sentence.
02

- Analyze Provided Choices

Look at each option and see how it fits into the sentence: 'No one seems certain of why the government took so long to recognize the benefits of a managed, skills-based immigration policy.'
03

- Evaluate Each Option

Evaluate the grammatical correctness and meaning preservation for each option: A. 'No one seems certain of why' - This option is grammatically correct. B. 'No one seems certain about why' - This option also maintains grammatical correctness. C. 'No one seems certain why' - This removes the preposition 'of,' which might affect the flow but still maintains meaning. D. 'He became certain why' - This changes the subject and does not fit grammatically. E. 'It is easy to be certain why' - This completely changes the meaning of the original sentence.
04

- Select the Best Option

Compare options A, B, and C, as these are the only grammatically correct and meaning-preserving choices. Options B and C simplify the original phrasing slightly but sufficiently. Option C ('No one seems certain why') is the most natural and concise.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

grammar evaluation
Grammar evaluation is crucial in GMAT sentence correction questions. You need to identify errors related to sentence structure, verb agreement, and preposition usage. In the provided exercise, we began by evaluating the grammatical correctness of each answer choice:
  • Option A: 'No one seems certain of why' - This is grammatically correct, including the necessary preposition 'of.'
  • Option B: 'No one seems certain about why' - This also maintains grammatical accuracy with appropriate preposition use.
  • Option C: 'No one seems certain why' - Although it omits the preposition 'of,' it still remains grammatically sound and is often preferred in modern usage for its simplicity.
  • Option D: 'He became certain why' - This introduces a different subject 'He,' which completely changes the intended meaning and is grammatically incorrect given the context.
  • Option E: 'It is easy to be certain why' - This shifts both the subject and the sentence meaning, thus making it grammatically incorrect relative to the original sentence.
This evaluation shows that only Options A, B, and C remain viable for preserving the original grammatical structure.
answer choices analysis
Answer choices analysis involves examining each option to see if it logically fits within the sentence. Let's look at how each one performs within the context:
'No one seems certain of why the government took so long to recognize the benefits of a managed, skills-based immigration policy.'
We need to ensure that the replacement does not alter the original message. Here’s the analysis:
  • Option A fits well without causing any abrupt shifts in meaning.
  • Option B, while also grammatically correct, introduces 'about' which does not add to the clarity or meaning of the sentence. Instead, it makes it slightly less concise.
  • Option C is the simplest and most direct, maintaining both grammatical integrity and conciseness.
  • Option D changes the subject, creating a contextually incorrect sentence.
  • Option E not only shifts the subject but also entirely changes the focal point of the sentence.
The comparison shows that A and C are good options, but C is preferred for its simplicity and natural flow.
meaning preservation
Preserving the original meaning is critical in sentence correction questions. When evaluating changes, it's vital to ensure the core message remains unchanged. The original sentence is:
'No one seems certain of why the government took so long to recognize the benefits of a managed, skills-based immigration policy.'

Let's assess the options based on how well they preserve the meaning:
  • Option A ('No one seems certain of why') preserves the meaning perfectly, keeping the focus on the uncertainty about the government's delay.
  • Option B ('No one seems certain about why') maintains the meaning, although it adds an unnecessary word ('about') which does not change the context significantly but can be seen as a bit redundant.
  • Option C ('No one seems certain why') keeps the same meaning, and its concise nature may make it more impactful.
  • Option D ('He became certain why') shifts the focus to an individual's certainty, which is not what the original sentence conveys.
  • Option E ('It is easy to be certain why') alters the meaning entirely, suggesting certainty rather than questioning it.
Therefore, we see that while A and B are close, C preserves the original meaning most effectively while enhancing readability.
