I would choose A. Samantha is testing the actual question "how many LIBRARY books are checked out by 7th graders at SAME time". She is still getting a result to the question, but an inaccurate reading as we do not know if ALL 7th graders are present in library and she is only doing a portion of 7th graders checking out books. However, Luis is going to cafe and some may never have gone to library or dislike reading tangible material. Basically both are bad surveyors, but Luis is definlately performing a more random approach.
Answer:
C. It supports the scientific explanation for global warming.
Explanation:
The listed pieces of empirical evidence support the scientific explanation for global warming. Global warming is the long-term heating of Earth's climate, and the increase in levels of carbon dioxide and methane is the reason why glacial ice in the Antarctic and Arctic sea is melting.
These pieces of evidence don't deal with the past of the future. They tell us what is going on right now. Based on them, we could make an assumption about what is going to happen in the future, but there are no predictions here.
Also, this data can be used for science journals and textbooks, but that purpose is not expressed here.
This leaves us with option C as the correct one.
