Well, you can eliminate "a terrible storm" and "a national emergency" because they make no sense whatsoever. Catastrophic means terrible, horrible, etc.
The answer for this question would be "C. Brutus is highly respected, and Cassius knows that joining with Brutus will give the conspirators credibility."
I hope this helps!!
If you circle the globe, you are going to find yourself back where you started.
While walking the shore
At dusk one day
I saw a mist
of silver spray
Two creatures glided
through churning foam
to splash and play
before the gloam
As silent as death
mysterious as night
slipping through
the fading light
I watched them as
they passed from sight
a host of dolphins
in the pale moonlight
