The correct answer is:
Each year, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled.
The correct answer is: Each year, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled.
To determine the answer, we need to understand what Al Gore, author of An Inconvenient Truth, demonstrates about the level of atmospheric carbon dioxide (CO2) levels. The most accurate way to find this information is by reading the book or watching the documentary.
However, if we don't have access to the specific source, we can make an educated guess by considering the consensus among scientists and experts about the trend of CO2 levels. They generally agree that human activities, such as burning fossil fuels, have led to an increase in atmospheric CO2 levels. This increase is a key driver of climate change.
Option A, "Each year, the CO2 level rises and then falls. Over the past 50 years, it has steadily increased," does not align with the consensus as it states the CO2 levels rise and then fall, whereas the overall trend is a consistent increase.
Option B, "Each year, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled," is the most plausible answer. It suggests that the rate of CO2 increase has been accelerating, leading to a nearly doubled concentration over the past 50 years.
Option C, "Each year, the CO2 level decreases. Over the past 50 years, it has steadily decreased," contradicts scientific consensus on rising CO2 levels and is thus not supported.
Given our knowledge of the topic, the most likely correct answer is Option B.
