Task: Question Answering
Input (English): Passage: Next to sound shifts, there are ample examples of suffix differences. Often simple suffix shifts (like switching between -the, -ske, -ke, -je, ...), sometimes the suffixes even depend on quite specific grammar rules for a certain dialect. Again taking West Flemish as an example. In that language, the words "ja" (yes) and "nee" (no) are also conjugated to the (often implicit) subject of the sentence. These separate grammar rules are a lot more difficult to imitate correctly than simple sound shifts, making it easy to recognise people who didn't grow up in a certain region, even decades after they moved. Question: What piece of a sentence does West Flemish match the case of a "yes" or "no" to?
Output (English): subject
