ead and choose the option with the best explanation of why it is important to learn Spanish as a banker. To write expense reports. To manage properties. To help foreign clients. To read safety report

I would say to help foreign clients.

Explanation:

Because I'd say helping foreign clients is sort of the "all of the above."  1. If someone were to not speak English you got their back. And 2. you could write expense reports and read safety reports and everything all in Spanish, thus, helping foreign clients.

Hope this helps :)
