Answer:
B: greenhouse
Explanation:
Water vapor traps heat in the Earth's atmosphere. This serves to maintain Earth's atmospheric temperature. Based on this function, water can be classified as a greenhouse gas.
Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.
Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.
The correct answer is: It can be proven using objective evidence.
To be<em> factual</em> is to use or consist of facts, meaning the information provided can be proven and its characteristics are not altered by external interpretations (opinions from others).

President Kennedy's phrase "the bonds of injustice" refers to the social and economic oppression of the slaves' heirs. (option C)
<h3>What are "the bonds of injustice"?</h3>
First, it is important to understand the context given by the passage. President Kennedy is talking about the slaves who were freed by President Lincoln, and then he moves on to their heirs, that is, to all African Americans.
When President Kennedy mentions that those heirs are not freed from "the bonds of injustice," he means that African Americans still face social and economic oppression, that they are still not treated equally.
With the information above in mind, we can select option C as the correct answer.
