Can someone please help answer these english 2 questions? i beg you!?

I cant help you with the first four because you didn't underline anything. 5:an expectant hush falls over the audience . 6:and the workers crowded into the long tunnel. 8:e-mail. 9:whom. 10: modifier. 12: appeared. 13:because. 14: Unless you have a better solution, use the standard procedure until you hear otherwise. All the other questions i didn't answer had nothing underlined, so I don't even know.
