Final answer:
The median high temperature on a block in Austin with 35% tree cover might be slightly cooler due to the shade and transpiration provided by trees. Options a) 75°F or b) 80°F seem plausible, while c) 85°F and d) 90°F would be less likely considering the moderate tree cover.
Step-by-step explanation:
The question is asking to estimate the median high temperature on a block in Austin with 35% tree cover. Tree cover can influence local temperatures by providing shade and releasing moisture into the air through a process called transpiration, which can lead to local cooling. Considering that 35% is a moderate amount of tree cover, which can have a mild cooling effect compared to areas with little to no tree cover, the median high temperature might be on the lower end of the options provided.
Without specific temperature data for Austin or a specified time of year, we cannot definitively determine the exact median high temperature for Amal's block. However, taking a reasonable guess based on the aforementioned cooling effect of tree cover, option a) 75°F or b) 80°F could be plausible estimates for an area with moderate tree cover, as tree shade and transpiration would likely provide some cooling relief from the harsher temperatures that areas without tree cover might experience. Options c) 85°F and d) 90°F seem less likely if the tree cover is indeed providing a cooling effect, although, without more information on climate patterns in Austin, this is an educated guess rather than a certain fact.
