Improve the underlined part of the sentence by choosing the most appropriate option: “I left my job because I did not (agree to) the company appraisal policies.”

Introduction / Context:
This question focuses on correct preposition use with the verb “agree”. In English, “agree” combines with different prepositions depending on what follows, and examination questions often test these subtle differences. Here, the sentence is about a person not sharing the same opinion as the appraisal policies of a company. Choosing the correct preposition helps the sentence sound natural and grammatically accurate in formal communication such as reports, letters, and interviews.

Given Data / Assumptions:

• Original sentence: “I left my job because I did not agree to the company appraisal policies.”
• The underlined part is “agree to”.
• We have four options, including “No improvement”.
• The object after the verb is “the company appraisal policies”, that is, a set of rules or ideas.

Concept / Approach:
The verb “agree” can be used in several patterns. We generally use “agree with” to show that our opinions match those of a person, statement, idea, plan, or policy, for example, “I agree with you” or “I do not agree with this proposal”. We use “agree to” when we give formal consent to do something, such as “agree to the terms” or “agree to help”. We use “agree on” when people reach a common decision about a subject, as in “agree on a date”. Since the sentence talks about accepting or rejecting appraisal policies as ideas, “agree with the company appraisal policies” is the most accurate and idiomatic structure.

Step-by-Step Solution:

Verification / Alternative check:
We can compare a few correct sentences. For instance, “Employees agree with the new bonus scheme” and “Many citizens do not agree with the new tax policy” both show the pattern “agree with” followed by policies or rules. On the other hand, we use “agree to” when there is an implied act of consent, such as “She agreed to the surgery” or “He agreed to work overtime”. In the question, the speaker is expressing disagreement with the fairness or suitability of appraisal policies, not refusal to sign a specific contract document, so “agree with” is ideal. This cross check confirms our choice.

Why Other Options Are Wrong:

• Option A: “agree about” is used when people have the same opinion about a general topic, for example, “They agree about the need for reforms.” It is possible but less natural with a specific set of policies here, and exam usage prefers “agree with policies”.
• Option C: “agree on” is used when multiple people reach a joint decision on something, such as “agree on a date”. The sentence is not about a joint decision; it is about one person disagreeing with existing policies.
• Option D: “No improvement” retains “agree to the company appraisal policies”, which suggests formal consent to terms rather than general agreement. It is not the best choice for this context.

Common Pitfalls:
Learners often treat all prepositions after “agree” as interchangeable, which leads to awkward expressions. Another pitfall is thinking in terms of literal translation from other languages, where one preposition covers many English uses. In examinations, it is important to remember common collocation patterns: “agree with a person or idea”, “agree to a proposal or plan as consent”, and “agree on a matter when two sides reach the same decision”. Associating each pattern with clear example sentences helps fix them in memory and improves accuracy in questions of this type.

Final Answer:
The correct improvement is “agree with”, so the sentence should read: “I left my job because I did not agree with the company appraisal policies.”
