Answer:
able to be observed
Explanation:
Thus question refers to excrept from Mark Twain's novel "Roughing It".
The word "perceptible" would most effectively be explained as "capable of being perceived" and it originates from Latin word "percipere" which means to understand, to know something with one's senses.
In the paragraph 1, this word is used in a sentence " The snow lay so deep on the ground that there was no sign of a road perceptible...".

This is one of things only you could answer, but it seems you just don´t understand the question so I will explain it.
Its saying if you could give away one part of your personality (for example, always happy, sad) and replace it with something else, which would you get rid of and replace it with? why?
For example let's say my traits were : Sad, depressed, anxious
I want to remove depressed and replace it with : Sad, happy, anxious
And for the ¨why¨, ¨I don't want to be just sad anymore so I would replace depressed with happy so at least I can be happy sometimes.¨
Hope this helps.
