1. When we burn fossil fuels, we produce carbon dioxide. (D)

Burning fossil fuels releases carbon dioxide into the atmosphere, contributing to climate change and global warming. This is a well-known fact in the field of environmental science and has been extensively researched and proven.

2. Warm temperatures in the Arctic are causing the ice to melt. (B)

Rising global temperatures are causing the Arctic ice to melt at an alarming rate. This phenomenon is widely studied and documented by scientists and is a direct result of climate change. The melting ice is leading to rising sea levels worldwide, which has serious consequences for both human and animal populations.

3. He works at a research station in Antarctica. (A)

Antarctica is a place of interest for many researchers and scientists who conduct various studies related to climate change, environmental science, and other fields. The phrase "research station" clearly suggests that the person mentioned is involved in scientific research activities in Antarctica.

4. Sea levels are rising due to global warming. (C)

Rising global temperatures lead to the melting of ice caps and glaciers, which in turn causes the sea levels to rise. This is a direct consequence of global warming, caused primarily by human activities such as burning fossil fuels, deforestation, and industrial processes.

5. Paul took a course to learn how to live in the mountains. (A)

The word "survival" best fits the context here. Taking a course in survival skills would provide Paul with essential knowledge and techniques to safely navigate and live in the mountains. It would cover topics such as finding shelter, starting a fire, navigating, and finding food and water in a challenging mountain environment.

6. The hotel has a special offer on room rates for the long weekend. (B)

The word "special" indicates that the hotel has a discounted or attractive offer for customers. This is a common marketing strategy employed by businesses to attract more customers during specific periods such as long weekends or holidays.

7. He followed the footpath through the forest. (B)

A footpath is a narrow trail or path designed for walking. It is commonly found in natural areas such as forests and parks. By mentioning "footpath" in the context of a forest, it implies that the person followed a designated trail or path while navigating through the forest.

8. There are a lot of blizzards in Antarctica because of the cold temperatures. (D)

Antarctica is known for its extremely cold temperatures and harsh weather conditions. Blizzards, which are severe snowstorms characterized by strong winds and reduced visibility, are common occurrences in this region. The extreme cold and vast amount of ice and snow provide the conditions necessary for blizzards to form.

9. Dinosaurs became extinct millions of years ago. (C)

The word "extinct" means that a species no longer exists. Dinosaurs lived on Earth millions of years ago and became extinct due to various factors, including a large asteroid impact, climate change, and natural selection. The extinction of dinosaurs is a well-established scientific theory supported by extensive fossil evidence and research.

10. The weather is becoming unpredictable; changing from day to day. (B)

When the weather is unpredictable, it means that it is changing in an erratic or inconsistent manner. This could involve sudden shifts in temperature, unexpected rain or snowfall, or rapid changes in atmospheric conditions. Unpredictable weather patterns are often associated with climate change, which is causing shifts in traditional weather patterns around the world.
