Current maps showing the North American regions where different types of garden plants will flourish are based on weather data gathered 60 years ago from a few hundred primitive weather stations. New maps are now being compiled using computerized data from several thousand modern weather stations and input from home gardeners across North America. These maps will be far more useful.

Summarize Argument
The author concludes that the new maps will be far more useful. No evidence is provided for her claim.

Notable Assumptions
The author assumes that maps compiled using computerized weather data are more useful than maps based on primitive weather data gathered 60 years ago. In truth, this isn’t much of an assumption.

A
Home gardeners can provide information on plant flourishing not available from weather stations.
Home gardeners fill in the picture in the computer-assisted maps. The other maps don’t feature any home gardener input.
B
Some of the weather stations currently in use are more than 60 years old.
We have no idea if these weather stations are used in the new maps. Nor do we have any idea how the age of a weather station affects its ability to provide useful data.
C
Weather patterns can be described more accurately when more information is available.
The newer maps have more data than the old maps. Thus, they can more accurately describe weather patterns.
D
Weather conditions are the most important factor in determining where plants will grow.
These maps are designed to show where plants will grow. Since the new ones have better weather data, they’ll be more helpful.
E
Weather patterns have changed in the past 60 years.
Weather data from 60 years ago, which is what the old maps have, isn’t very helpful.
