Steppe (temperature continental) climate is characterized by dry summers and cold winters with moderate to low precipitation. It is usually found in regions located far from large bodies of water, such as oceans or large lakes. The temperature range is typically large, with hot summers and cold winters.

Among the given options, Pretoria, Saskatchewan, and Buenos Aires are all known to experience steppe (temperature continental) climate. These places are located in regions that are far from large bodies of water, and they exhibit the typical characteristics of this climate.

However, the correct answer is option 3: Perth. Perth is not known to experience steppe (temperature continental) climate. Instead, Perth has a Mediterranean climate, which is characterized by hot, dry summers and mild, wet winters. This climate is influenced by the nearby Indian Ocean, which moderates the temperature and provides higher precipitation compared to steppe climates.

Therefore, if the correct answer given is option 3 (Perth), it is indeed accurate. However, if the correct answer is stated as any other option, it should be regarded as an error.
