Meaning: 'After all' means 'considering everything' or 'in light of what has been said,' suggesting that the previous points support the conclusion being drawn.

Wrong options:

• For example: 'For example' introduces a specific instance or illustration, which does not align with the context of summarizing expectations.
• At the end: 'At the end' implies a conclusion or final point, but it does not fit the context of reinforcing the reasoning behind the expectation.
• In summary: 'In summary' suggests a recap of information, which is not the intended function here as it does not connect the previous ideas effectively.

Correct answer: according to

Explanation: The phrase 'according to' is used to attribute information to a source or perspective, making it grammatically and contextually appropriate as it indicates that the answer varies based on who is asked.

Meaning: 'According to' means 'as stated by' or 'in the opinion of,' indicating that the number of recognized countries can differ based on different viewpoints.

Wrong options:

• in terms of: 'In terms of' refers to specific aspects or criteria, which does not fit the context of varying opinions about the number of countries.
• regarding: 'Regarding' indicates a topic of discussion but lacks the nuance of attributing the variation to specific sources or opinions.
• as well as: 'As well as' is a conjunction that adds information but does not convey the idea of variation based on perspective.

Correct answer: arises

Explanation: The verb 'arises' indicates that a problem emerges or comes into being, fitting grammatically and contextually as it describes the nature of the problem related to the definition of 'country.'

Meaning: 'Arises' means 'comes up' or 'emerges,' suggesting that the problem is a result of the lack of a clear definition.

Wrong options:

• raises: 'Raises' implies bringing something up for discussion, which does not accurately describe the emergence of a problem in this context.
• comes: 'Comes' is too vague and does not convey the specific emergence of a problem as effectively as 'arises.'
• seems: 'Seems' suggests an appearance or perception, which does not accurately reflect the nature of the problem being discussed.

Correct answer: find

Explanation: The verb 'find' is used here to indicate that some countries discover it convenient to recognize or not recognize others, fitting grammatically and contextually as it describes a choice or realization.

Meaning: 'Find' means 'to discover' or 'to determine,' indicating that countries make a conscious decision regarding recognition.

Wrong options:

• state: 'State' implies declaring something, which does not fit the context of convenience in recognition.
• want: 'Want' suggests a desire but does not convey the active decision-making process involved in recognition.
• make: 'Make' is too general and does not specifically indicate the realization or decision process that 'find' conveys.
