Đáp án B

Giải thích: 

Theo đoạn 3, công nghệ mới hiệu quả hơn máy bơm nhiệt thông thường vì ________.

A. nhiệt được đưa vào nhà trong mùa đông và thoát ra ngoài vào mùa hè 

B. nhiệt độ đất và nước ngầm dao động ít hơn nhiệt độ không khí 

C. nhiệt độ mặt đất gần với nhiệt độ nước ngầm quanh năm 

D. không khí lạnh hấp thụ nhiệt ít hơn không khí ấm

Thông tin: Geothermal systems are more effective than conventional heat pumps that use the outdoor air as their heat source (on cold days) or heat sink (on warm days) because geothermal systems draw heat from a source whose temperature is more constant than that of air. 

Tạm dịch: Hệ thống địa nhiệt hiệu quả hơn các máy bơm nhiệt thông thường cái mà sử dụng không khí ngoài trời làm nguồn nhiệt (vào những ngày lạnh) hoặc tản nhiệt (vào những ngày ấm áp), vì hệ thống địa nhiệt hút nhiệt từ nguồn có nhiệt độ ổn định hơn không khí. 

Chọn B.
