It seems like you're providing a list of answers to a set of questions, but you haven't mentioned what those questions are. In order to be able to provide assistance, I need to know what the questions are.

However, I can guide you on how to find the answers to your questions on your own. If you have a list of questions and corresponding answer choices, you can use a variety of methods to find the correct answers:

1. Review study materials: If you have access to study materials, textbooks, or lecture notes related to the subject of the questions, you can review them to find information that aligns with the answer choices.

2. Conduct research: If you're struggling with a particular question, you can use internet search engines, online resources, or academic databases to look up information related to the question. Be sure to use reliable sources to ensure accuracy.

3. Consult with peers or instructors: If you're studying with others or have access to a teacher or professor, you can reach out to them for guidance or clarification on any confusing questions. They may be able to provide additional resources or insights.

Remember, it's important to understand the reasoning behind the correct answers rather than simply memorizing a list of solutions. This will help you gain a deeper understanding of the subject matter and apply your knowledge effectively in different scenarios.
