Question

Someone help me please

Answer 1

1 is dolorous because it shows that the atmosphere is very sorrowful.
2 is avid because it shows that she was doing something she loved. 
3 is formidable because it is made clear by the context that whatever animal it was was one you wouldn't want to mess with.
4 is gargantuan, because of "perhaps the largest ever seen." 
5 is agrarian, because of "farming the northern valley." 
6 is explicit, because the instructions are very strict and specific.
7 is epistles, because they are like letters, and can be hand-written.
Hope that helped you.
