Answer 3

I can chat with you in English, but I cannot understand your first sentence. It looks like you are using a different language. Maybe you can try to translate it using [Bing Translator](https://www.w3schools.com/python/python_user_input.asp).

Your second sentence is a question about modal verbs in English. Modal verbs are words that express possibility, necessity, obligation, permission, or ability. They are used with a main verb to form a sentence. For example, "She can sing very well" means that she has the ability to sing very well.

The correct answer to your question is A) Could. Could is a modal verb that can be used to make polite requests or ask for permission. For example, "Could you speak louder, please?" means that you are asking someone to speak louder in a polite way. Other modal verbs that can be used for polite requests are can, may, and would.
