Title ĐỀ SỐ 38 - HS.docx ✅

Mã đề 101 Page 2/6 One of the primary obstacles is Mars's thin atmosphere, which is composed mostly of carbon dioxide. This means that the air on Mars is unbreathable for humans, and the lack of a magnetic field exposes the planet to harmful solar radiation. Scientists are exploring the possibility of creating habitats with controlled environments to protect humans from these harsh conditions. Terraforming Mars’s environment to make it more Earth-like has also been suggested but remains in the realm of theoretical science due to its enormous technical and resource demands. Another challenge is the limited availability of water. Although evidence of frozen water and underground ice has been found, extracting and purifying it for human use requires advanced technology. Furthermore, the extreme temperatures on Mars, which can drop below -60 degrees Celsius, pose additional difficulties for survival and infrastructure. Additionally, dust storms on Mars can last for months and cover the entire planet, severely impacting visibility, solar power, and human activity. Despite these challenges, space agencies like NASA and private companies such as SpaceX are actively working towards sending humans to Mars. Proposals include sending robotic missions to build habitats in advance and developing technologies for sustainable life-support systems. Engineers are also experimenting with 3D-printed materials to construct structures using Martian soil. If successful, humans may one day establish a permanent presence on Mars, paving the way for interplanetary colonization. While the journey to Mars is fraught with difficulties, the potential to expand human civilization beyond Earth remains an exciting prospect for the future. Question 23. Which of the following is NOT mentioned as a challenge of living on Mars? A. Difficulties in providing access to breathable air for humans. B. The need to protect habitats from long-lasting dust storms. C. The inability to generate sufficient solar energy during storms. D. Harmful radiation due to the absence of a magnetic field.

C. purification processes used to create safe drinking water. D. water that must be processed for human survival. Question 26. The word terraforming in paragraph 2 could best be replaced by _______. A. conducting experiments on an uninhabited planet. B. transforming planetary conditions to resemble Earth. C. altering a natural environment to make it habitable.
