The terms 'Event Horizon', 'Singularity', 'String Theory' and 'Standard Model' are sometimes seen in the news in the context of
A
Observation and understanding of the Universe
Correct Answer
B
Study of the solar and the lunar eclipses
C
Placing satellites in the orbit of the Earth
D
Origin and evolution of living organisms on the Earth
Explanation
These terms represent fundamental concepts in astrophysics and particle physics—specifically black holes (Event Horizon, Singularity) and the nature of matter and forces (String Theory, Standard Model)—which are essential for observing and understanding the Universe. Option (c) is incorrect because these terms describe theoretical frameworks and cosmic phenomena rather than the practical engineering and mechanics involved in satellite deployment. The core concept being tested is the candidate's familiarity with contemporary scientific terminology related to cosmology and fundamental physics.
