Even though there is no options to choose, I have got that one which is the most suitable. The relevant detail to <span>Frederick Douglass's autobiography is :
</span>The mush was put into a large wooden tray, or trough, and set down upon the ground. I am pretty sure you had this option given with the task, because this one is universal and will help you in any case.
I think in this case the prepositional phrase would be early.
The subordinate clause is "unprotected animals got swept out" and the main clause is because "when waves rush in". hope u get it right ;)
After test would be your answer for sure :)
