According to An Inconvenient Truth, what is the role of infrared radiation in global warming?
(1 point)
Responses
All of the sun’s energy is converted to infrared radiation and then remains in the atmosphere. This warms the atmosphere.
Over time, infrared radiation makes the atmosphere thinner. This warms the atmosphere.
Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
According to An Inconvenient Truth, the role of infrared radiation in global warming is that greenhouse gases trap some infrared radiation in the atmosphere, which warms the atmosphere.
In which sentence below is the underlined word an indirect object?
(1 point)
Responses
Gore published An Inconvenient Truth a few years after he ran for president
My sister gave me a signed copy of the book.
She said she preferred the documentary film.
The sentence in which the underlined word is an indirect object is "My sister gave me a signed copy of the book." In this sentence, "me" is the indirect object as it receives the action of the verb "gave" and indicates to whom the signed copy of the book was given.
