Hi!
Since snails go really slowly, and it says "SLOWING my thoughts...", we can interpret that he/she isn't thinking of things very fast. Our brains can think things so fast, normally we don't even have to think about it. (Wow, how many times can I say 'think' in one sentence?) But he/she is having that process slowed, probably because he/she can only focus on how cold he/she is.
Hope this helps!

The answer is A. True. Exposition is being used in order to show the connection between the present topic to some background information in order to create a more vivid or clear description about the topic. Exposition is like using flashback with the use of information. Whereas, description is the use of words in order to add more picture to the essay or speech. Both can be combined with writing essays and speeches.
