(01.01 MC) Read the two questions.

Question 1: Is change in atmospheric CO2 levels likely to impact marine life?
Question 2: Should diesel and gasoline engines compliant with CO2 emission standards be banned?

Use complete sentences to explain whether both questions can be answered by science or not. Be sure to explain why for each question.

This is what i said - just want to know what others think - is it correct or incorrect ? What do i need to change in my answer ?

Is change in atmospheric CO2 levels likely to impact marine life? = If the answer to the question cannot be tested and observed, it is not considered science.
Should diesel and gasoline engines compliant with CO2 emission standards be banned? = If the question is asking about an opinion or a moral value, it's not something that can be measured using a scientific process. Therefore, it cannot be answered with science.
