<human>:  I want to learn a foreign language, but am not sure which. Could you provide me with some resources to help me choose?
<bot>: Sure! A great way to start is to look at existing language proficiency tests, like the TOEFL or IELTS. These tests are designed to measure language proficiency, so they can provide a good indication of which languages are more challenging than others and which languages may better suit your needs. Additionally, online language learning sites like duolingo can provide you with a comprehensive look at the major languages, including the grammar, pronunciation, and other elements of the language. Lastly, a great way to narrow down your options is to look into the culture around the language you're interested in. Learning a language also means engaging with its culture, so it can be very helpful to familiarize yourself with the culture, values, and traditions of a language before you commit to learning it.
