Câu hỏi: Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the questions.
National parks play a highly valuable role in documenting climate change. Researchers have utilized the vast tracts of pristine wilderness to collect data on species and habitats. At first, they collected observational data on foot; now, they use sophisticated methods such as aerial surveillance with drones like those used in Northrop Grumman's Wildlife Challenge to collect information on polar bears.
Observational longitudinal data collection shows the effects of climate change that impact vegetation and animal species. The pika is the perfect example of an animal who may need to be relocated from the parks due to climate change, as described in Smithsonian Magazine. The park service is taking this very seriously. "It is … openly discussing the possibility of "assisted migration": manually relocating some animals and plants if it turns out they can't survive within the park's changing landscapes."
National park research also documents glacier retreat, finding that some ice fields have lost as much as 85 percent in the last five decades, according to U.S. Geological Survey. Glacier Park might be recognizable only as a historical name by 2030, it projects. It's not just glaciers retreating. The Conversation notes that national park data shows that trees are also affected by climate change: "Climate change is killing trees due to increased drought, changes in wildfire patterns and increased bark beetle infestations. Tracking of trees in … national parks has contributed to a database that revealed how climate change has doubled tree mortality since 1955 across the western United States."
We should not forget that at its inception, the National Parks Service's long-term intention was to protect the parks and "leave them unimpaired for the enjoyment of future generations."
A. Aerial tracking through the use of drones.
B. Observation information gathered when walking.
C. Reports of jungles turning into residential areas.
D. Data on areas of unspoiled hinterland.

Theo đoạn 1, các nhà khoa học không tận dụng điều gì khi lưu giữ hồ sơ về sự thay đổi khí hậu?
A. Theo dõi trên không thông qua việc sử dụng máy bay không người lái
B. Thông tin quan sát được thu thập khi đi bộ
C. Báo cáo về rừng rậm biến thành khu dân cư
D. Dữ liệu về các khu vực nội địa hoang sơ
Căn cứ vào thông đoạn đầu:
Researchers have utilized the vast tracts of pristine wilderness to collect data on species and habitats. At first, they collected observational data on foot; now, they use sophisticated methods such as aerial surveillance with drones like those used in Northrop Grumman's Wildlife Challenge to collect information on polar bears.
(Các nhà nghiên cứu đã sử dụng các vùng đất rộng lớn hoang sơ để thu thập dữ liệu về các loài và môi trường sống. Lúc đầu, họ thu thập dữ liệu quan sát khi đi bộ; bây giờ, họ sử dụng các phương pháp tinh vi như giám sát trên không với máy bay không người lái giống như những loại được sử dụng trong thử thách động vật hoang dã Northrop Grumman để thu thập thông tin về gấu Bắc Cực.)
