For Judy's conclusion on the climate being tropical based on her data collected over one week, the MOST important reason why her conclusion might NOT be correct is:
D. She made her conclusion based only on one week of data instead of over a long period of time.
Climate is defined as the long-term average of weather patterns over time, typically over many years, rather than just a week-long observation.
For the question about how latitude and air temperature are related, the sentence that BEST describes this relationship is:
C. The higher the latitude, the colder the air temperature.
In general, as you move away from the equator (lower latitude) towards the poles (higher latitude), air temperatures tend to decrease.
