Correct answer: specific

Explanation: The word 'specific' is appropriate as it describes the particular industries, regions, and occupations affected by structural unemployment. It fits grammatically as an adjective modifying the noun 'industries.'

• structural: 'Structural' is already used to describe the type of unemployment and does not fit as a descriptor for industries.
• traditional: 'Traditional' refers to established practices and does not specify the industries affected by unemployment.

Correct answer: traditional

Explanation: The term 'traditional' fits well as it describes the heavy industries that have historically been part of the economy in certain regions. It is grammatically correct as it modifies 'industries.'

Meaning: 'Traditional' refers to industries that have been established for a long time and are now in decline.

Wrong options:

• controversial: 'Controversial' does not apply as it does not describe the nature of the industries.
• social: 'Social' is unrelated to the economic context of industries.
• structural: 'Structural' is already used to describe a type of unemployment and does not fit as a descriptor for industries.
• specific: 'Specific' does not convey the historical context needed to describe the industries in question.

• controversial: 'Controversial' does not fit as it does not relate to the positioning of industries.
• settled: 'Settled' implies a state of being established but does not accurately describe the geographical aspect of industries.
• replaced: 'Replaced' is a verb that indicates substitution, which does not fit in this context as it does not describe location.

Correct answer: replaced

Explanation: 'Replaced' is the correct answer as it indicates that traditional industries have been substituted by cheaper imports. It fits grammatically as the past participle in the passive construction.

Meaning: 'Replaced' means to be substituted with something else.

Wrong options:

• controversial: 'Controversial' does not fit as it does not relate to the action of substitution.
• settled: 'Settled' implies a state of being established but does not convey the action of being replaced.
