It appears that the text provided is incomplete and contains typographical errors, making it difficult to understand the full context and requirements of the question. However, based on the guidelines provided, I will attempt to address the first three parts of the question if they were present.

Since the text is not clear, I will outline a general approach to answering a question with multiple parts:

1. Read the question carefully: Ensure you understand what is being asked. Look for keywords and context clues.
2. Apply relevant knowledge and principles: Use your understanding of the subject matter to address the question.
3. Display reasoning or derivation steps clearly: Show how you arrived at your answer, including any calculations or logical steps.

Given the incomplete and unclear nature of the text, I cannot provide specific answers. If you can provide a clearer or more complete version of the question, I would be happy to assist further.
