Question 3

Daily high temperature in Chicago is 70% greater than its daily low temperature.

In Chicago, the daily high temperature exceeds the daily low temperature by 70%. This percentage reflects the significant variation in temperature that can occur within a single day in this city.

A) 14%

This option is incorrect as a 14% difference would suggest a much smaller variation between the daily high and low temperatures. Such a minor percentage would not adequately capture the typical temperature fluctuations observed in Chicago.

B) 41%

A 41% difference indicates a moderate variation between high and low temperatures, but it still underestimates the substantial temperature changes that can occur in Chicago, making it an inaccurate choice.

C) 56%

Although a 56% difference represents a considerable variation, it still falls short of the actual percentage increase observed in the daily high compared to the daily low temperature in Chicago, thus making it incorrect.

D) 70%

This option accurately reflects the significant increase of 70% in the daily high temperature compared to the daily low temperature in Chicago. This percentage effectively captures the typical variations experienced in the region.

E) 90%

While a 90% difference might indicate an extreme fluctuation, it exaggerates the actual temperature variation observed in Chicago. This makes it an incorrect representation of the typical daily temperature range.

Conclusion

The correct answer, 70%, clearly represents the expected increase in daily high temperatures compared to the lows in Chicago, highlighting the city's notable temperature variations. The other options fail to accurately depict this relationship, making them incorrect choices in this context.
