Answer: I don't understand your question, but it appear to be related to punctuation. Periods are used at the end of sentences to signal when the sentence is over and where you should pause. Commas are used to separate clasues and make sentences more coherent. Fragment sentence are imcomplete sentence. For example "Cat sat." Run on sentences are sentences that run on and are not puctuated correctly. For example, "The cat ate a rat and then he sat on a mat and then he slept in a groove on his bed before using the litter box and then he received a belly rub and found a piece of moldy pie with dried up cranberries on top which he threw in the trash because he is a very smart cat." As you can see, grammar is very important.
