Again, as a non-native English speaker, you realize that some verbs have a different meaning when you add a second word. For example, the verb take, take in vs take on, they have different meanings. I will put here some examples and I will try to explain them.
As a non-native English speaker, this is a very common question when to use these adverbs. We understand the meaning of them: to state a possibility. However, you may have read or listened to them in very different contexts.
When I was studying for my CELPIP exam I got material from them. Unfortunately, I can not put the PDF to the public because it has a watermark with my personal email. But I can put you here what it says.
CELPIP's thirtieth error as they state:
In the CELPIP Speaking Test, you will be asked to respond to a series of questions about many different things. Some questions are related to illustrations or conversations, while others ask about your preferences or opinions. It is important to answer each question in a clear and organized fashion. When test takers don't organize their ideas, they have difficulty developing the topic. The listener also has to work harder to identify and follow the ideas.
In an organized response, ideas flow together in a logical, sequential, or easy-to-understand manner, and the listener can easily understand your meaning. Before you start your response, you should use up to twenty seconds to organize what you want to say. Use the paper and pencil provided to note down key ideas and order them logically. The chart below provides some guidance on how to approach some, but not all, questions types on the CELPIP Speaking Test.
