The underlined words and phrases have strong negative connotations. How do they support the author's purpose?

They draw attention to the opinion that the United States

is not doing enough to help these children

They show that there is a desperate need for all

countries to be willing to help refugees

They show that the United States has participated in

international conventions on how to handle the refugee

crisis

They make it clear that the United States will lose the

respect of other nations if it does not help these children

This question is missing the excerpt. I've found it online. It is the following:

Read the excerpt from "Children of the Drug Wars."

By sending these children away, "you are handing them a death sentence," says José Arnulfo Ochoa Ochoa, an expert in Honduras with World Vision International, a Christian humanitarian aid group. This abrogates international conventions we have signed and undermines our credibility as a humane country. It would be a disgrace if this wealthy nation turned its back on the 52,000 children who have arrived since October, many of them legitimate refugees.

The underlined words and phrases have strong negative connotations. How do they support the author's purpose? [...]

They support the author's purpose because:

A. They draw attention to the opinion that the United States  is not doing enough to help these children.

Explanation:

Even though the excerpt is missing the underlined words and phrases, there is only one option that has any true connection with what is being said. The excerpt is about how the U.S. has been failing to help children who arrive in the country as refugees. Instead of welcoming them with care and safety, they are often sent away, back to their countries. It is clear that the U.S. is not doing enough for those children. Therefore, the correct option is letter A.

Options B through D can be easily eliminated. This excerpt does not concern other countries' roles in this crisis, international conventions, or the  way in which the U.S. will be regarded by other nations.
