In the following question, out of the four alternatives, select the alternative which will improve the bracketed part of the sentence. In case no improvement is needed, select "no improvement". Sentence: "What seeds you (has sow) in the garden of your mind determine the quality of life you shall have."

Introduction / Context:
This sentence improvement question focuses on subject–verb agreement and correct verb forms in a somewhat poetic sentence. The sentence uses an extended metaphor comparing thoughts in the mind to seeds in a garden. To answer correctly, you must identify the appropriate verb form that fits both the grammatical structure and the intended meaning.

Given Data / Assumptions:

The full sentence is: "What seeds you (has sow) in the garden of your mind determine the quality of life you shall have."
The phrase "what seeds you ... in the garden of your mind" functions collectively as the subject of the sentence.
The main verb for this subject is "determine", which is correctly in the plural form, suggesting a plural or collective subject.

The bracketed part "has sow" is clearly grammatically incorrect and needs correction.

Concept / Approach:
We need a verb form that fits the pattern "What seeds you ____ in the garden of your mind" and works naturally with "determine the quality of life you shall have." Here, "you sow" is a simple present tense clause, expressing a timeless truth or general principle: the seeds you sow (your thoughts and actions) determine your future. The word has is unnecessary and the base form sow should be used directly after the subject you. Using a gerund or past form would break the intended general, habitual sense of the sentence.

Step-by-Step Solution:
Step 1: Identify the structure: "What seeds you ____ in the garden of your mind determine the quality of life you shall have." Step 2: Recognise that the clause "you sow in the garden of your mind" describes a general action, not a completed or ongoing specific time frame. Step 3: The correct simple present form for the subject you is sow. Step 4: Insert option B: "What seeds you sow in the garden of your mind determine the quality of life you shall have." This Now reads smoothly and expresses a general principle. Step 5: Option A sowing would give "What seeds you sowing in the garden..." which is ungrammatical. Step 6: Option C had sow is incorrect because had should be followed by the past participle sown, and even then "had sown" would shift the meaning to a completed action in the past rather than a general rule. Step 7: Option D no improvement is not possible because "has sow" is clearly wrong; the auxiliary has should be followed by the past participle "sown" and is not needed after you. Step 8: Option E have sown would create "What seeds you have sown in the garden..." which describes past actions and does not sit well with the proverb-like structure of the sentence.

Verification / Alternative check:
Think of similar proverb-style sentences: "What you sow, you reap" or "The habits you develop determine your future." These use simple present forms to state general truths. "What seeds you sow in the garden of your mind determine the quality of life you shall have" fits this pattern perfectly. Also, the plural verb determine agrees naturally with the implied plural subject "what seeds you sow". If we used "have sown", we would be focusing on past actions, which would not match the general, timeless tone of the sentence.

Why Other Options Are Wrong:
Option A sowing incorrectly mixes a gerund with a finite clause and does not fit after the subject you.
Option C had sow is doubly wrong: had should be followed by a past participle "sown", and the past perfect tense is not needed here.
Option D no improvement would retain "has sow", which is grammatically incorrect because has is not properly followed by a past participle, and the subject you does not agree with has in this structure.
Option E have sown shifts the sentence into present perfect, indicating completed past actions, which weakens the proverb-like, general truth meaning intended by the writer.

Common Pitfalls:
Learners sometimes overuse perfect tenses, especially have + past participle, in sentences that actually require the simple present to express general truths. A good rule is: when a sentence reads like a proverb or universal principle, and there is no reference to a specific time, the simple present tense is usually the safest and most correct choice. Checking the agreement between the subject and the main verb (determine) also helps confirm that "you sow" fits naturally in the structure.

Final Answer:
The bracketed part should be improved to "sow", giving: What seeds you sow in the garden of your mind determine the quality of life you shall have.
