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. It makes trees experience longer growing seasons.
B. It increases the death rates of trees through disturbances.
C. It creates a negative change in wood density.
D. It causes lumber from trees to be less durable.

B. It increases the death rates of trees through disturbances.
C. It creates a negative change in wood density.
D. It causes lumber from trees to be less durable.
Theo đoạn 3, biến đổi khí hậu ảnh hưởng đến cây như thế nào?
A. Nó làm cho cây trải qua mùa sinh trưởng dài hơn
B. Nó làm tăng tỷ lệ chết của cây thông qua các xáo trộn
C. Nó tạo ra một sự thay đổi tiêu cực của mật độ gỗ
D. Nó làm cho gỗ từ cây kém bền
Căn cứ vào thông đoạn ba:
"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." ("Biến đổi khí hậu đang giết chết cây do hạn hán gia tăng, thay đổi mô hình cháy rừng và gia tăng bọ cánh cứng phá hoại. Theo dõi cây trong ... vườn quốc gia đã góp phần vào cơ sở dữ liệu, cái mà tiết lộ sự thay đổi khí hậu đã làm tăng gấp đôi tỷ lệ tử vong của cây kể từ năm 1955 trên khắp miền tây Hoa Kỳ.")
