30. Which of the following is a supporting detail in this passage?

Answer: A

Explanation:

There are two separate kitchens, both adorned with marble countertops and brand-new stainless-steel appliances.

This detail highlights specific features of the estate that contribute to its appeal and luxury, making it a key supporting detail in the passage.

A) There are two separate kitchens, both adorned with marble countertops and brand-new stainless-steel appliances.

This statement directly illustrates the luxurious amenities of the estate, emphasizing the quality and sophistication of the kitchens, which are integral to the overall description of the property. It provides concrete examples of what makes the home desirable.

B) This house offers myriad amenities for a reasonable price.

While this option suggests the house's appeal, it does not provide specific details or supporting evidence from the passage. The claim about price is also not mentioned or substantiated within the provided extract, making it less relevant.

C) All information listed is deemed reliable by the listing agent but cannot be guaranteed and should be independently verified.

This statement serves as a disclaimer rather than a supporting detail about the property itself. It does not describe any features or qualities of the house, thus failing to support the main description.

D) This house will retain its value on the real estate market.

This option makes a speculative claim about the house's future value, which is not supported by any details in the passage. The extract focuses on current features and amenities rather than future market predictions.

Conclusion

The correct answer is clearly supported by the passage, as it provides specific details about the kitchens, which enhances the reader's understanding of the property’s luxury and functionality. All other options either lack specific references to the estate's features or present unverifiable claims, making them less relevant as supporting details.
