A sounds like the most likely answer, since it shows that she cares for him and wants to do something special for him.
The correct answer is A. It starts with very specific details, devoid of any emotional interfering on the narrator's part. The only subjective detail in this line is the estimation "very strange". Still, it doesn't disturb the factuality of the context, which is firmly rooted in precise time and place references.
D is the answer because the verb is dripping due to fact that that's the action and the mood is indicative because indicative means revealing and it reveals that the dripping paintbrush will get paint on you if you're not careful.
<span>Thoreau appeared to both a pacifist and a rebel in this passage. He says in paragraph 7 to go at one's pace and to not answer the call of society just because one feels obligated. He is saying that we should not fret over something just because it is present and others fret over it. He sets this up in paragraph 6 by saying if man would just stop for a second and consider what is permanent and not fleeting (the temporary pain, problem), then he would find all that is important are things of great important and permanence. So he says to the whistle that it can just continue to, well, whistle. He realizes the great truth that he cannot control what others do, or what things cry for attention, but he can certainly control whether or not let reacts to it.</span>
