A.I. Explanation:

Correct answer: cases

Explanation: The word 'cases' fits grammatically as it refers to specific instances of corruption, aligning with the plural context of 'one of the country's biggest corruption cases.' It is also contextually appropriate as it indicates distinct occurrences of corruption, which is the focus of the sentence.

Meaning: 'Cases' refers to specific instances or examples of something, in this context, it means particular instances of corruption.

Wrong options:

• scenarios: 'Scenarios' implies hypothetical situations or sequences of events, which does not fit the factual context of corruption instances.
• matters: 'Matters' is too vague and does not specifically denote instances of corruption, making it less precise in this context.
• phenomena: 'Phenomena' refers to observable events or occurrences, typically used in scientific contexts, and does not accurately describe corruption instances.

Correct answer: branch

Explanation: The term 'branch' is the correct choice as it refers to a local office of a bank, which fits the context of the sentence describing Xu Guojun's position. It is grammatically correct as it aligns with the structure of the sentence and contextually appropriate as it specifies the type of bank location.

Meaning: 'Branch' refers to a local office or division of a larger organization, in this case, a bank.

Wrong options:

• joint: 'Joint' typically refers to something shared or combined, which does not apply to a bank's location.
• store: 'Store' is more commonly associated with retail and does not accurately describe a banking institution.
• station: 'Station' is generally used for transport hubs and does not fit the context of a banking office.

Correct answer: embezzling

Explanation: The word 'embezzling' is the correct answer as it specifically refers to the act of wrongfully taking or misappropriating funds entrusted to one's care, which is the crime Xu Guojun was convicted of. It fits grammatically and contextually within the sentence.

Meaning: 'Embezzling' means to illegally take money that one has been entrusted to manage, typically in a professional setting.

Wrong options:

• sinking: 'Sinking' does not relate to financial crimes and is more commonly associated with physical objects or ships, making it irrelevant here.
• pocketing: 'Pocketing' implies taking money for oneself but is less formal and specific than 'embezzling,' which is the legal term for the crime.
• shipwrecking: 'Shipwrecking' refers to the destruction of a ship and is completely unrelated to financial misconduct.

Correct answer: programme

Explanation: The word 'programme' is appropriate as it refers to a planned series of activities or initiatives aimed at addressing corruption, fitting well within the context of President Xi Jinping's efforts. It is grammatically correct and contextually relevant as it describes a systematic approach to tackling corruption.

Meaning: 'Programme' refers to a planned series of actions or initiatives designed to achieve a specific goal, in this case, combating corruption.

Wrong options:

• system: 'System' implies a set of connected things or parts, which is too broad and does not convey the specific initiative context as effectively as 'programme.'
• lineup: 'Lineup' typically refers to a group of people or things arranged in a line, which does not apply to the context of anti-corruption efforts.
• specimen: 'Specimen' refers to an example or sample of something, which does not fit the context of a structured initiative.

Correct answer: crackdown

Explanation: The term 'crackdown' is the correct choice as it refers to a severe or strict enforcement action against wrongdoing, which aligns with the context of addressing corruption in the banking sector. It fits grammatically and contextually within the sentence.

Meaning: 'Crackdown' means a strong or severe action taken to stop or control something, particularly illegal activities.

Wrong options:

• seizure: 'Seizure' refers to taking possession of something, usually by legal authority, and does not convey the proactive enforcement aspect of combating corruption.
• oppression: 'Oppression' implies prolonged cruel or unjust treatment, which does not specifically relate to the enforcement actions against corruption.
• intervention: 'Intervention' suggests involvement to alter a situation but lacks the connotation of strict enforcement that 'crackdown' provides.
