We can actually deduce here that the astronaut that raised his hand actually said that the colour of the feather placed on his helmet was blue and going further to give a logical explanation, he explained that this is because the sky of the planet where they are is blue.
<h3>What is logical explanation?</h3>
Logical explanation actually refers to the explanation that is given using logic and what everyone sees and knows. In logical reasoning, one speaks based on what he/she knows or acquires from reasoning or thinking through.
