Meaning: 'Of becoming' refers to the process or state of transitioning into something else, in this case, languages transitioning into extinction.

Wrong options:

• have become: This option suggests a completed action, which does not fit the ongoing nature of languages currently in danger.
• to become: This option implies a future possibility rather than the current state of danger, making it less suitable here.
• became: This past tense option indicates a completed action, which does not align with the ongoing situation described.

Correct answer: prefer

Explanation: The verb 'prefer' is appropriate here as it indicates a choice or inclination towards using more widely spoken languages. It fits both grammatically and contextually, as businesses are actively choosing to use these languages.

Meaning: 'Prefer' means to like one thing more than another, indicating a choice in language usage by businesses.

Wrong options:

• fancy: This informal term does not convey the same level of decision-making as 'prefer' and is less suitable in a formal context.
• select: While 'select' could imply choice, it lacks the nuance of preference that 'prefer' conveys, making it less fitting here.
• must: This modal verb indicates necessity rather than choice, which does not align with the context of businesses choosing languages.

Correct answer: has had

Explanation: The phrase 'has had' is correct as it indicates a completed action relevant to the present, fitting the context of discussing opportunities that have already passed. It maintains subject-verb agreement with 'anyone' as a singular pronoun.

Meaning: 'Has had' refers to the experience of having an opportunity in the past that is relevant to the present situation.

Wrong options:

• have: This plural form does not agree with the singular subject 'anyone,' making it grammatically incorrect in this context.
• would have: This conditional phrase suggests a hypothetical situation rather than a completed action, which does not fit the context.
• having had: This gerund form is awkward in this context and does not convey the intended meaning of a completed action.

Correct answer: deal

Explanation: The word 'deal' fits well as it refers to a significant amount or quantity of information. It aligns with the context of discussing the value of information that could be revealed by these languages.

Meaning: 'Deal' in this context means a large amount or quantity, indicating the potential richness of information from local languages.

Wrong options:

• size: This term does not convey the same sense of quantity or significance as 'deal' and is less appropriate in this context.
• capacity: While it suggests potential, it does not imply the same quantity of information as 'deal,' making it less fitting here.
• load: This term implies a burden or weight, which does not align with the positive connotation of valuable information.

Correct answer: argue

Explanation: The verb 'argue' is suitable here as it indicates a position or assertion made by historians regarding the importance of language. It fits grammatically and contextually, as historians often present arguments based on evidence.

Meaning: 'Argue' means to present reasons for or against something, indicating that historians assert the importance of preserving language.

Wrong options:

• speak: This verb does not convey the same assertive meaning as 'argue' and is too vague in this context.
• tell: While it suggests communication, it lacks the argumentative nuance that 'argue' provides, making it less suitable.
• explore: This verb implies investigation rather than assertion, which does not fit the context of historians making a claim.
