The correct answers are A. Challenging; C. Exhaustive note taking and D. Time-consuming lab work

Explanation:

The word "demand" refers to something or someone that is challenging or requires an intensive effort that is not normally required in a similar situation. This means if a teacher is classified as demanding is generally because this teacher asks students for more than other teachers do. In the excerpt presented, in which the Biology teacher called Professor Ramirez is described, the narrator emphasizes this teacher is "the most challenging course" which means this course and requires require more than the narrator expects. Also, the narrator describes the class sessions require "exhaustive not taking and time-consuming lab work" that also explain the way teacher Ramirez is demanding. Additionally, the narrator describes other positive features of the teacher such as "inspiring" or "students remain engaged" that do not relate to the demanding aspect. Thus, the words that support the idea that Professor Ramirez is a demanding teacher are "challenging" which is a synonym for demanding; "exhaustive note-taking" and "time-consuming lab word" which explain the ways in which this teacher demands more from students than others which refers to the concept of demanding.
