Meaning: 'Prevailed' means to be victorious or to succeed, especially after a struggle, indicating that good sense has finally won out.

Wrong options:

• precluded: 'Precluded' means to prevent something from happening, which contradicts the positive sentiment of the sentence.
• prevented: 'Prevented' also implies stopping something from occurring, which does not fit the context of good sense succeeding.
• presented: 'Presented' refers to showing or offering something, which does not convey the idea of triumph or success.

Correct answer: has

Explanation: The word 'has' is the correct form of the verb to agree with the singular subject 'the centre.' It indicates that the centre has been actively seeking to withdraw the ban, fitting the present perfect tense used in the sentence.

Meaning: 'Has' is a form of the verb 'to have,' used here to indicate possession or action in the present perfect tense, showing that the action is relevant to the present.

Wrong options:

• have: 'Have' is used with plural subjects, which does not agree with the singular subject 'the centre.'
• been: 'Been' is the past participle of 'be' and cannot stand alone without an auxiliary verb, making it grammatically incorrect here.
• has been: 'Has been' suggests a continuous action, but the context requires a simple present form to indicate the current action.

Correct answer: concern

Explanation: The word 'concern' fits well as it indicates a feeling of worry or anxiety about the implications of the rules. It aligns with the context of the sentence, which discusses apprehensions regarding government actions.

Meaning: 'Concern' refers to a feeling of worry or interest about something, in this case, the potential negative impact of the rules on cattle trade.

Wrong options:

• dispute: 'Dispute' implies a disagreement or argument, which does not capture the emotional aspect of worry expressed in the sentence.
• belief: 'Belief' refers to an acceptance that something is true, which does not convey the same sense of worry or apprehension as 'concern.'
• recognition: 'Recognition' means acknowledging something, which does not fit the context of expressing worry about the government's actions.

Correct answer: dietary

Explanation: The word 'dietary' is appropriate as it relates to the diet or food habits of individuals, fitting the context of the sentence discussing animal trade and its implications on consumption.

Meaning: 'Dietary' pertains to the kinds of food that a person habitually eats, indicating how the rules may affect people's eating habits.

Wrong options:

• daily: 'Daily' refers to something occurring every day, which does not specifically relate to food habits as 'dietary' does.
• nutritional: 'Nutritional' pertains to the nutrients in food, but it does not directly address the habits of eating as 'dietary' does.
• intake: 'Intake' refers to the amount of food consumed, which is not as precise in describing the habits as 'dietary' is.
