Rewrite the sentence below, correcting the problem of incorrect omission. astronomers on the whole understand the solar system better than chemists. i'm not sure what i need to add or omit. would it be or could it " astronomers as a whole understand the solar system better than chemists.?

Incorrect: Astronomers on the whole understand the solar system better than chemists.

Correct: Astronomers on the whole understand the solar system better than chemists understand it.

Explanation:

A problem of incorrect omission happens when we omit necessary words in a sentence and therefore, we change the meaning of the sentence. The sentence provided has this problem because it is lacking a few words that are necessary. Without the words "understand it," the sentence conveys that Astronomers understand the solar system better than they understand chemists. However, in reality, the sentence wants to communicate that Astronomers, on the whole, understand the solar system better than chemists understand it (the solar system).

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.
