Adobe is an ideal material for building in desert environments.
Evidence
[Adobe] conducts heat very slowly.
As a result, a house built of adobe retains the warmth of the desert sun during the cool evenings and then remains cool during the heat of the day, thereby helping to maintain a pleasant temperature.
In contrast, houses built of other commonly used building materials, which conduct heat more rapidly, grow hot during the day and cold at night.
Conclusion
Adobe is an ideal material for building in desert environments.
Evaluate
The argument compares adobe with other building materials with regard to their ability to conduct heat and argues that adobe is an ideal material for building in the desert.
