<h3>What is global warming?</h3>
This exercise is about global warming, which is the warming of the planet's overall temperature.
I was able to find the complete instructions for the exercise online:

Option D is the only one that can give you background information because the other options give you specific information about some of the topics that are related to global warming, but not background and
general information.
