In this sentence improvement item, decide whether the bracketed verb phrase "(has become)" in the sentence about feminist criticism turning into a political discourse needs any change.

Introduction / Context:
This question tests the correct use of present perfect tense to describe a development that has taken place over time. The sentence states that feminist criticism has transformed into a political discourse and a critical theoretical practice. The bracketed phrase "has become" must be evaluated to see whether it correctly expresses this change that has relevance in the present.

Given Data / Assumptions:

• Subject: "The feminist criticism", treated as a singular abstract concept.
• Bracketed verb phrase: "has become".
• The sentence talks about a transformation that has occurred and still matters.
• Options: "have becoming", "has became", "became", and "No improvement".

Concept / Approach:
Present perfect tense for a singular subject uses "has" plus the past participle. The past participle of "become" is "become" itself, not "became". Therefore "has become" is grammatically correct. It also suits the meaning, because the development of feminist criticism into a political discourse began in the past and continues to define its role now. The alternative "became" is simple past and would remove the sense of ongoing relevance, while "has became" is simply incorrect in form.

Step-by-Step Solution:
Step 1: Identify the subject "The feminist criticism" as singular. Step 2: Recall the rule: singular subject plus present perfect uses "has" and a past participle. Step 3: Note that "become" has the same form for base, past participle, and sometimes past, but the simple past in this verb family is normally "became". Step 4: Confirm that "has become" is the correct present perfect form. Step 5: Conclude that no change is needed and select "No improvement".

Verification / Alternative check:
Read the sentence with the given verb phrase: "The feminist criticism has become a political discourse; a critical and theoretical practice committed to the struggle against patriarchy and sexism." This is exactly how academic writing describes intellectual movements that have evolved over time. Using "became" would imply a completed event in the past without highlighting current continuity. "Has became" is ungrammatical, and "have becoming" does not follow any standard pattern. Thus, the original phrase is both grammatically and stylistically appropriate.

Why Other Options Are Wrong:
"Have becoming" is incorrect because "have" should be followed by a past participle, not a present participle.

"Has became" mixes a correct auxiliary with the wrong verb form; "became" is not a past participle.

"Became" alone is simple past and loses the sense of a development that still matters in the present.

Common Pitfalls:
Students sometimes become confused by irregular verbs whose past participle is not clearly different from the simple past. A good habit is to memorise verbs like "come", "become", and "run" along with their correct perfect forms: "has come", "has become", "has run". Checking a reliable list of irregular verbs will help confirm these patterns. In exam settings, combinations like "has became" should always alert you as incorrect.

Final Answer:
The phrase "has become" is already correct, so the best choice is "No improvement".
