"Today nobody brought his or her instrument" is correct. It is common for people to use "their" in a sentence like this, but "his or her" is the more proper term.
It is Subjunctive. Conditionals use "If"
I believe it is number 5. at the end of the conclusion. Hope this helped!
Thanks!

Referring to the notion of equality in the midst of a wartime social revolution, as African Americans walked off southern plantations and into the northern army, Lincoln seemed to be pushing the country forward. The president called on Americans to dedicate themselves to “the unfinished work” of those who had fought at Gettysburg, thus joining America’s founding ideal of equality with African Americans’ aspirations for liberty.
The correct answer is:
