* Sentence length varies greatly. A sentence could be as short as "Go!" or as long as a paragraph.
* Punctuation determines sentences. A period, question mark, or exclamation point signals the end of a sentence. Without knowing the punctuation, we can't count sentences.
For example:
* Scenario 1: 50 words could be one very long sentence.
* Scenario 2: 50 words could be 10 short sentences.
* Scenario 3: 50 words could be a mix of long and short sentences.
To determine the number of sentences, you need the actual text!
