I need you to help me write a handbook about "Requirements and Iterative Development ". Now I give you a memory (a brief summary) of 400 words, you should use it to store the key content of what has been written so that you can keep track of very long context. For each time, I will give you your current memory (a brief summary of previous stories. You should use it to store the key content of what has been written so that you can keep track of very long context), the previously written paragraph, and instructions on what to write in the next paragraph. I need you to write: 

1. Output Paragraph: the next paragraph of the novel. The output paragraph should contain around 20 sentences and should follow the input instructions. 

2. Output Memory: The updated memory. You should first explain which sentences in the input memory are no longer necessary and why, and then explain what needs to be added into the memory and why. After that you should write the updated memory. The updated memory should be similar to the input memory except the parts you previously thought that should be deleted or added. The updated memory should only store key information. The updated memory should never exceed 20 sentences! 

3. Output Instruction: instructions of what to write next (after what you have written). You should output 3 different instructions, each is a possible interesting continuation of the story. Each output instruction should contain around 5 sentences Here are the inputs:

Input Memory: (short memory) 
Input Paragraph: {input_paragraph} 
Input Instruction: {input instruction) 
Input Related Paragraphs: {input long-term memory} 

Now start writing, organize your output by strictly following the output format as below: 
Output Chapter: <string of output Chapter>
Output Section: <string of output Section>
Output Subsection: <string of output Subsection>
Output Paragraph: <string of output paragraph>, around 20 sentences. 

Output Memory: 
Rational: <string that explain how to update the memory>; 
Updated Memory: <string of updated memory>, around 10 to 20 sentences 

Output Instruction: 
Instruction 1: <content for instruction 1>, around 5 sentences 
Instruction 2: <content for instruction 2>, around 5 sentences 
Instruction 3: <content for instruction 3>, around 5 sentences 

Very important: The updated memory should only store key information. The updated memory should never contain over 500 words! Finally, remember that you are writing a handbook . Write like a specialist and do not move too fast when writing the output i Please reply with exactly 5 paragraphs and separate each paragraph with two new lines. The very first paragraph must start with the word "several".
