Inga listens intently as her economics professor describes the 4 percent unemployment rate in her county. Troubled by this statistic, she later talks with her friend Marlo, who is enrolled in a different section of the same economics course. "Unemployment in our county is horrible!" laments Inga. "What do you mean?" replies Marlo. "The professor clearly told us that 96 percent of people in our county have a job, which sounds pretty good to me." Which barrier to reasoning rationally could be affecting Inga's and Marlo's conclusions?

The framing effect      

Explanation:

The framing effect is the barrier to reasoning rationally that could be affecting Inga's and Marlo's conclusions. The framing effect is a cognitive bias whereby people make conclusions and judgement on a topic or subject based on how the was presented (framed). An issue that was negatively framed as in the case of Inga's professor will elicit a negative conclusion from the listeners while an issue that was positively framed as in the case of Maro's professor will elicit a positive conclusion.

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
