What were the major industries that saw development during the 'Great Depression' of the 1930s?

Okay, let's talk about the 1930s and the 'Great Depression'. It was a really tough time globally, but even during economic hardship, some industries still managed to grow and innovate. While traditional industries like coal mining and shipbuilding were struggling due to decreased demand and oversupply, new technologies were starting to take off. Aviation was becoming more accessible, and the development of commercial airlines and passenger planes was accelerating. Think about it: people were starting to travel by air more frequently. Similarly, the automobile industry continued to develop, with cars becoming more affordable and reliable. This meant more people could own them, leading to increased production and infrastructure development like roads and highways. So, while many sectors were in decline, aviation and automobile industries were actually expanding and innovating, making them the correct answer. Coal mining and shipbuilding were very much industries of the past at this point, and were not seeing any new development.
