Text 1A4-II The pursuit of space exploration represents one of the most captivating undertakings of the human race, serving as a testament to our inherent drive to comprehend the cosmos and our position within it. As humanity expands its reach beyond the confines of Earth, the intricate and essential relationship between technology and law grows increasingly intricate and indispensable. The rapid progress of technology has ushered us into an era when endeavours in outer space, previously confined to the realm of science fiction, are now becoming tangible and feasible. The present circumstances require a comprehensive legal structure encompassing the existing range of space endeavours and the flexibility to accommodate dynamic technological advancements. The Outer Space Treaty of 1967 set the foundational legal principles governing space exploration activities. However, as humanity continues to explore space and private companies participate alongside sovereign nations, the intersection of technology and law serves as both a catalyst for progress and a cause of disagreement. Bansi Kaneria; Shivam Pandey. Interplay Between Technology and Law in Space Exploration. In : IOSR Journal of Environmental Science Toxicology and Food Technology , 2024, 18 (03): 31-46 (adapted).

The expression “a comprehensive legal structure” (second sentence of the second paragraph) could be correctly replaced, maintaining the original meaning of text 1A4-II, with

A an understandable system of laws.
B a compassionate system of legal principles.
C a compedium of laws.
D a thorough legal framework.
E a manageable legal structure.

C has a meaning similar to has guided .
D is written in the singular because of the word “technology”.

Text CB1A2 Spending time in space and having an unrivalled view of planet Earth is an experience many of us dream of, but the human body evolved to function in the gravity of Earth. So fully recovering from spending time in the weightlessness of space can take years. “It’s a fact that space is by far the most extreme environment that humans have ever encountered and we’ve just not evolved to handle the extreme conditions,” Professor Damian Bailey, who studies human physiology, says. To begin with, the heart and blood vessels have an easier time as they no longer have to pump blood against gravity — and they start to weaken. And the bones become weaker and more brittle. There should be a balance between the cells breaking down old bone and those making new, but that balance is disrupted without the feedback and resistance of working against gravity. “Every month, about 1% of bones and muscles are going to wither away — it’s accelerated ageing,” Professor Bailey says. Microgravity also distorts the vestibular system, which is how you balance and sense which way is up. In space, there is no up, down or sideways. It can be disorientating when you go up — and again when you return to Earth. James Gallagher. What nine months in space does to the human body. Internet: (adapted).

It can be inferred from text CB1A2 that

A the heart and blood vessels become more active because they have to work harder in space.
B people feel off balance when they travel to space because of its dimensions.
C the view of Earth from space is unlike any other thing a person may experience.
D space is more dangerous for humans than extremely cold places on Earth.
E there are no harmful physical effects for people who spend less than a month in space.

Considering the second paragraph of text CB1A2, choose the correct option.

A In the excerpt ‘it’s accelerated ageing’, the word ‘it’ is a singular pronoun replacing ‘1% of bones and muscles’.
B In the fragment ‘It’s a fact that space is by far the most extreme environment that humans have ever encountered’, ‘that’ is a pronoun replacing the word ‘It’.
C In “Professor Damian Bailey, who studies human physiology”, omitting the comma would not change the meaning of the fragment or harm its correctness.
D In the fragment “There should be a balance between the cells breaking down old bone and those making new”, the word “those” refers to the cells that make bones smaller.
E In the second sentence of the paragraph, both occurrences of the pronoun “they” refer to “the heart and blood vessels”.

A are used to describe physical conditions limited to people who travel into space.
B can be understood as expressions used to describe the ‘accelerated ageing’ mentioned by Professor Bailey.
C are verbs used to describe what happens to human muscles when in space.
D can be respectively and correctly replaced with flexible and wear out.
