I think it would be number 4
The correct answer to this open question is the following.
I am going to explore the environmental issues/attitudes that I see in the media, taking the case of the film "An Inconvenient Truth," produced by former Democratic candidate to the presidency of the United States, Al Gore.
The film, released in 2006, tries to create conscience about the difficult topic of the damage that humans are inflicting on the environment and how mother Earth tends to react when so much noise, air, and water pollution abounds on the planet. The central topic is global warming, and the film presents testimonials and statistics about the increasing pollution levels in most parts of the earth and the damage industries and means of transportation causes the planet due to carbon dioxide.
Other pieces of literature support these concerns, meanwhile, the Bible warned of the kind of destruction that was created in the past if we sin and do not respect nature as a creation of God.
The right answer for the question that is being asked and shown above is that: "adverbial clause." The underlined part of sentence 1 is an adverbial clause<span>(1) that creatures living in the deep sea are in danger of starving to death</span>
