The correct answer is A. How long does it take a paper bag to break down?
Explanation:
The scientific process or method refers to an organized set of steps or procedures used to study natural phenomena. This means the scientific method can be used to study events that can be observed and tested and do not depend on subjective perspectives.
According to this, the question that can be answered using this process is "How long does it take a paper bag to break down?" because this phenomenon can be observed and tested; for example you can test if the time is different for a paper bag to break down depending on the soil or place where it is. Additionally, other options such as "should people feel bad for using paper bags?" or " is it right for a grocery store to use plastic bags'" are subjective and therefore cannot be answered using this method.
