Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.1. Light behaves as a wave when it exhibits properties like interference and diffraction, which are fundamental characteristics of waves.2. The particle nature of light is evident in the photoelectric effect, where light knocks electrons off a material, demonstrating its particle-like properties.3. The wave and particle aspects of the same phenomenon were announced by Niels Bohr in 1928.4. The wave-particle duality of light is a cornerstone of quantum mechanics, illustrating that light possesses both wave-like and particle-like properties.5. When light passes through a double-slit, it creates an interference pattern on a screen, a behavior typical of waves.

Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.1. The detection of gravitational waves opened a new window into understanding the universe, allowing astronomers to observe phenomena that were previously invisible.2. Despite its significance, this discovery also posed questions about the sustainability of space exploration and its environmental impact on Earth.3. This breakthrough led to a deeper understanding of black holes and neutron stars, shedding light on some of the most mysterious objects in the cosmos.4. One of the most remarkable achievements in recent years has been the direct observation of gravitational waves, confirming a major prediction of Einstein's theory of relativity.5. As a result, scientists were able to provide more evidence supporting the Big Bang theory, offering insights into the early moments of the universe.
