the question concerns exactly this part of the speech:

i am not now thinking of the loss of property involved, immense and serious as that is, but only of the wanton and wholesale destruction of the lives of non-combatants, men, women, and children, engaged in pursuits which have always, even in the darkest periods of modern history, been deemed innocent and legitimate. property can be paid for; the lives of the peaceful and innocent people cannot be.

president wilson talks about the lives of people destroyed by german army. but these people are not americans, they are the local people living in europe. the president mentions the barbarity of germans, considering that he is not targeting the nation, instead it is said about german army. the correct answer is the last one.

this question is not school related. refrain from asking non school or academic related questions in the future.

" animal is healthy and eternally gratefully that you provided him with a warm home." and "the health and well-being of our animal friends is what is at stake here."

synonim for get by is to survive, therefore, the answer is survive.
