Read the passage and answer the question. When Mei arrived at the university, she found that lectures moved much faster than those in high school. At first, she tried to write down every word her professors said, but her notes were always incomplete. After talking with her tutor, she decided to take up a note-taking system that used symbols and abbreviations instead of full sentences. Within a few weeks, she was able to keep pace with the lectures and still have time to review. Her roommate, impressed by the change, asked how she had managed to take in so much information during class. Mei explained that the real skill was not recording everything, but selecting the key points. She also warned her roommate not to take on too many club activities, since a heavy schedule had once left her too tired to concentrate in lectures. Now Mei feels far more confident, and she believes any student can adapt if they are willing to adjust their methods. Question: What does the phrase "take up" most probably mean in the sentence "she decided to take up a note-taking system"? A. To begin to use or adopt something new B. To remove or take something away C. To hire someone for a particular job D. To continue doing something without change
