Meaning: 'Would' is a modal verb used to express a conditional situation or a possibility, indicating that something might occur under specific circumstances.

Wrong options:

• would: Correct option, indicating a hypothetical situation.
• was: 'Was' is a past tense verb that does not fit the conditional context of the sentence, as it implies a completed action rather than a potential state.
• could: 'Could' suggests possibility but lacks the conditional nuance that 'would' provides in this context, making it less suitable here.
• can: 'Can' indicates ability or possibility in the present, which does not align with the hypothetical nature of the statement.

Correct answer: significance

Explanation: The term 'significance' fits contextually as it refers to the importance or meaning of the mountain, which is the focus of the sentence. It aligns with the historical context mentioned, indicating that the mountain's value was recognized in ancient times.

Meaning: 'Significance' means the quality of being worthy of attention or importance, highlighting the mountain's historical and cultural value.

Wrong options:

• treachery: This word refers to betrayal or deceit, which is unrelated to the context of the mountain's importance.
• difficulty: 'Difficulty' implies a challenge or obstacle, which does not relate to the recognition of the mountain's value.
• productivity: While 'productivity' relates to output or efficiency, it does not capture the essence of the mountain's historical importance.

Correct answer: economy

Explanation: The word 'economy' is appropriate here as it refers to the system of production and consumption in a region. The context indicates that the exploitation of the mountain's salt contributed to the financial growth of Cardona, making 'economy' the most fitting choice.

Meaning: 'Economy' refers to the wealth and resources of a region, particularly in terms of production and consumption, highlighting the financial aspect of the mountain's exploitation.

Wrong options:

• roller-coaster: This term refers to a type of amusement ride and does not relate to the economic context of the sentence.
• foolhardy: This word describes reckless behavior, which is not relevant to the economic implications of the mountain's salt production.
• income: While 'income' relates to earnings, it is too narrow in scope compared to 'economy,' which encompasses the broader financial system.

Correct answer: addition

Explanation: The word 'addition' fits well as it indicates something that is added to what already exists. In this context, it refers to the extra activity of making salt sculptures alongside the mineral export, making it a logical choice.

Meaning: 'Addition' means something that is added, highlighting the locals' new activities in conjunction with the existing mineral export.

Wrong options:

• excess: This term implies an overabundance, which does not fit the context of adding new activities.
• again: 'Again' suggests repetition, which is not relevant to the introduction of new practices by the locals.
• order: This word refers to arrangement or command, which does not align with the context of adding new activities related to salt.
