Answer:
<em>B </em><em>Terror and Fear</em>
<em />
as the paragraph mentions
*ahem*<em> "groan of mortal terror. It was not a groan of pain or of"</em>
and <em>"echo, the terrors that distracted me. I say I knew it" </em>
shall hint to the reader the <em>idea of this passage</em>
this will remove A <em>Upbeat ending </em>as a correct option
reading the full passage at the half/end, It doesn't seem as a life or death so we can also remove <em>D </em><em>life or death</em> as an option it may see, that way but it doesn't really give us a sight of death or live blossoming
and <em>C </em><em>a unsolved mystery</em>
doesn't appear to be one, it may give us that thought at the beginning
but it mentions <em> "I knew what the old man felt, and pitied him,"</em>
which should say we k<em>now it's no mstyery</em>
<em />
Helping verb because it is before the main verb and is HELPING the sentence make sense. Without 'has' the sentence will be My brother eaten all the chili in the pot. That doesn't make sense
Hope that helped!
