Self-study
Geographer: Because tropical storms require heat and moisture, they form especially over ocean surfaces of at least 26 degrees Celsius (79 degrees Fahrenheit), ocean temperatures that global warming would encourage. ███ ████ ███████ ████ █████ ███████████ ██ ██████ ███████ █████████ ████ ██ █████ █████ ████ ████████ ███ ███████ ████████ ███████ ███ ██████ ████████ █████ ████ ████ ██████████ ██ ████████ ██ ██ █████ ████ █████ ████████ ████ ██ █████████████ ██ ████ █████ ███ ██████ ██ ██████████ ██████ █████████ ███████ ██ ████████ █████ ████████████
Summarize Argument: Phenomenon-Hypothesis
Global warming is unlikely to cause more frequent and intense tropical storms. Early predictions suggested that global warming would increase the frequency and intensity of tropical storms by raising ocean temperatures conducive to such storms. However, this is unlikely because global warming will have other effects, such as changes in wind flow, that will counteract its impact on tropical storm development.
Identify Conclusion
The conclusion is the geographer’s opinion that early predictions about global warming’s impact on tropical storm development were wrong. The geographer concludes that global warming will probably not cause more frequent and intense tropical storms.

Which one of the following ████ ██████████ █████████ ███ ██████████ █████ ██ ███ ████████████ █████████
a
Tropical storms are ██████████ ██████ ██ ████ ████ ████ █████ █████████
This answer is incorrect because it summarizes the context of the stimulus. It explains why some predicted that global warming would lead to more frequent and intense tropical storms: tropical storms are more likely to form over warm oceans.
b
Contrary to early ████████████ ██████ ███████ ██ ███ ███ ████ ██████ █████████ ███ █████████ ███ █████████ ██ ████████ ███████
This misstates the conclusion. The correct conclusion is that global warming will probably not result in more frequent and intense storms. However, this answer claims that the conclusion is about global warming not being the only factor affecting storm frequency and intensity.
c
If global warming ████ █████████ ████████ ██████ █████ ██ ████ ████████ ███ ████ ████████
This isn’t an argument made in the stimulus. The geographer doesn’t consider what would be required to reverse global warming; she only disputes one prediction about the effects global warming may have. Since this claim isn’t made in the stimulus, it can’t be the main conclusion.
d
Instabilities in wind ████ ████ ██████ ███ ██████ ██ ██████ ███████ ██ ███ █████████ ██ ████████ ███████
This addresses a premise, not the main conclusion. The geographer uses global warming's effect on wind flow to support her conclusion that global warming won't lead to more intense and frequent storms. Since this claim is supporting evidence, it can't be the main conclusion.
e
Global warming probably ████ ███ ███████ ████ ████████ ███ ███████ ████████ ███████
This accurately captures the main conclusion: the geographer believes that predictions about global warming’s effect on tropical storms were likely incorrect. The answer summarizes this by stating that global warming probably won't lead to more frequent and intense storms.
