Problem: God:

The earliest written form of the Germanic word God (always, in this usage, capitalized) comes from the 6th-century Christian Codex Argenteus. The English word itself is derived from the Proto-Germanic * uan. The reconstructed Proto-Indo-European form * ghu-to-m was likely based on the root * ghau()-, which meant either "to call" or "to invoke". The Germanic words for God were originally neuterapplying to both gendersbut during the process of the Christianization of the Germanic peoples from their indigenous Germanic paganism, the words became a masculine syntactic form.

Problem: Railway electrification system:

In comparison to the principal alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions and lower operating costs. Electric locomotives are usually quieter, more powerful, and more responsive and reliable than diesels. They have no local emissions, an important advantage in tunnels and urban areas. Some electric traction systems provide regenerative braking that turns the train's kinetic energy back into electricity and returns it to the supply system to be used by other trains or the general utility grid. While diesel locomotives burn petroleum, electricity is generated from diverse sources including many that do not produce carbon dioxide such as nuclear power and renewable forms including hydroelectric, geothermal, wind and solar.

electricity is generated from non-renewable forms including?

A: unanswerable

Problem: Iran:

In 1941, Reza Shah was forced to abdicate in favor of his son, Mohammad Reza Pahlavi, and established the Persian Corridor, a massive supply route that would last until the end of the ongoing war. The presence of so many foreign troops in the nation also culminated in the Soviet-backed establishment of two puppet regimes in the nation; the Azerbaijan People's Government, and the Republic of Mahabad. As the Soviet Union refused to relinquish the occupied Iranian territory, the Iran crisis of 1946 was followed, which particularly resulted in the dissolution of both puppet states, and the withdrawal of the Soviets.

Mohammad Reza Pahlavi established what enormous supply route during World War 2?
---
A:
the Persian Corridor
