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.
We see here that logically thinking, the helmet placed on their heads actually denoted sky and the blue feather denotes the colour of the sky. Remember they were told not to look up. That means what we are looking for is up which is the sky.
Thus, we can say here that the colour of the feather placed on his helmet is blue and it actually talks about the colour of their planet.

The primary problem is the greenhouse effect. Greenhouse effect is when some gases (including CO2) absorbs some portion of sun's heat to make the atmosphere warm to support life. But when the amount of CO2 etc. increases in the atmosphere, it heats up more than it is required. So, by limiting CO2 emission, we can solve this problem.
<u>Two different small paragraphs with formal tone and informal tone:</u>
Formal writing style is the one which describes every sentence in a very proper way. It does not makes use of contractions such as ‘it’s’, rather use ‘It is.’ When we use formal tone, there’s no space for first or third person (I,we) Example of formal tone is:
‘Over the past few years, education systems have come up with many new changes. Today’s education is no longer restricted within books. Rather, there are a wide number of applications, tutorials, and videos available online to expand and widen the knowledge of a child.’
Informal writing style is very casual. It is very much similar to how we have a conversation with our friends on a regular basis. Example if informal tone is:
‘Today, if we look around, we’ll notice that every person is engaged in some or the other social networking sites. We no longer interact with our friends and relatives face to face like we used to earlier. It’s you and me who needs to bring changes to change the present state.’
