Summarize Argument
Baumgartner’s comparison of environmental hazard is misleading. Why? Because he neglects elements essential to determining environmental impact.
Identify Conclusion
The conclusion is a critique of Baumgartner’s comparison: “Baumgartner’s comparison of the environmental hazards of gasoline-powered cars with those of electric cars is misleading.”
21.
Which one of the following ████ ██████████ █████████ ███ ██████████ ██ ███ █████████
a
Baumgartner makes a █████████ ██████████ ███████ ███ █████████████ ███████ ██ ████████████████ ███ ████████ █████
This is a good restatement of the conclusion. The rest of the argument supports this by showing that Baumgartner has neglected vital considerations.
b
The use of █ ███████ ████████████████ ███ ███████ ██ ████ ███████ ████████ █████████ ████ ████ ███ ███ ██ █ ███████ ████████ ████
This is premise. It provides support for the idea that including the use of different cars is necessary to accurately compare environmental impact.
c
Baumgartner uses inaccurate ████ ██ ███ ██████████ ██ ███ █████████████ ███████ ██ ████████████████ ███ ████████ █████
The author claims that Baumgartner is considering an incomplete set of information. That’s not the same as inaccurate data. Baumgartner’s production data may be 100% accurate, but the resulting comparison is still misleading.
d
The total life █████ ██ █ ███████ ██ ████ ███████ ██ █████████ ███ █████████████ ███████
This is a sub-conclusion. Because the total life cycle is what matters, Baumgartner is using incomplete information when he only considers production. (D) supports the conclusion that Baumgartner’s comparison is misleading.
e
The production of ████████████████ ████ ███████ ████ █████████████ ███████ ████ ████ ████ ██ ████████ █████
The author doesn’t address this. We know that the author believes that gas-powered cars use more resources, but we can’t assume that the author also believes they create more environmental hazard.
