<span>The correct answer for the question that is being presented above is this one: "c. a logical and intelligent person who is impressed by Sherlock Holmes's powers of deduction." In "The Adventure of the Blue Carbuncle," Dr. Watson is describes as a logical and intelligent person who is impressed by Sherlock Holmes's powers of deduction</span>
I dont think this might be correct but I think the answer is the 3rd one.
"Grass" is actually a poem that was written by Carl Sandburg. This is a poem in which he has published right after the World War I which is in the year 1918. Based on this poem, you can sense an unforgiving tone in it. Therefore, I can say that the attitude that the author expresses is "anger". Hope this answer helps.
