I find the possible answers not optimal for answering how varied ones languages are. Not only because of the mistakes in reading the question, that some people already mentioned, but also because the first answer is pretty wide:
"1) The same family with the same or different script, or another family with the same script."Basically no matter what language you learned - if it did not have another script than your native language - you will get this category.
But you will also fall into this category, if it's the same language family, but has a different script.
Because the Latin script is used for a huge varity of languages this category includes:
- A Spanish person learning Portuguese or Italian. (same family, same script)
- A Bulgarian learning Polish. (same family, different script)
- An Italian learning Dutch. (same script)
- A French learning Finnish or Hungarian (still same script, though quite different family)
- A Swede learning Vietnamese. (Because vietnamese is nowadays written with a script, that is based on Latin characters with diacritics for the tones)
There have been several languages that switched their writing to the Latin script in the past, and I assume, more will follow.
This map on wikipedia shows actually how widely spread the Latin script is, though it does not show smaller languages, so it definitely has its flaws.
Despite the first category being so wide more than 50% picked answer 2 and 3, which I find honestly quite surprising, considering that it was supposed to only include languages that are already intermediate or higher.
