Hacer una parrillada basically means to have a barbecue in Spanish. Although you didn't write any options here, I managed to find them elsewhere: la nube, el cielo, la cereza, and el fosforo.
La nube is a cloud, el cielo is the sky, la cereza is a cherry, and el fosforo is phosphorus, which is obviously necessary for having a barbecue. Thus the correct answer is el fosforo.
The phrases creating a tone of foreboding are:
- "strange blight;"
- "evil spell;"
- "mysterious maladies;"
- "shadow of death."
<em>Foreboding</em> means predicting or announcing that something bad is about to happen. Taking the answers one by one, you can see how they relate to the same ominous idea:
- a "strange blight" and "evil maladies" refer to a destructive condition which no-body can explain;
- an "evil spell" means that it is interpreted as a magical curse;
- the "shadow of death" is a metaphor meaning that death is coming to the crops or cattle (depending on the original text excerpt).
"there is a last sweet and kind,
was never face so pleased my mind
I did but see her passing by
and yet I love her till I die
