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 correct answer to this multiple-choice question, we can use the information provided in the question stem, which states that Al Gore, the author of "An Inconvenient Truth," demonstrates something about the level of atmospheric carbon dioxide (CO2) levels.
We need to carefully read each response option and compare it to the information given.
Response 1 states that each year, the CO2 level rises and then falls, while over the past 50 years, it has steadily increased. This contradicts the information given in the question stem, which implies that there is a consistent trend over the past 50 years.
Response 2 states the same information as response 1, only with a minor formatting difference. Again, it contradicts the information given in the question stem about a consistent trend over the past 50 years.
Response 3 states that each year, the CO2 level increases at a faster rate, and over the past 50 years, it has nearly doubled. This seems to align with the information provided in the question stem - a consistent increase over the past 50 years.
Response 4 claims that each year, the CO2 level decreases, and over the past 50 years, it has steadily decreased. This directly contradicts the information given in the question stem, which implies an increase, not a decrease.
Based on our analysis, we can conclude that the correct answer is Response 3: Each year, the CO2 level increases at a faster rate. Over the past 50 years, it has nearly doubled.
