Final answer:
The best activity to help Nicki develop her observant function is option B, which is to focus on her current assignment and take notes. This method promotes active engagement and presence in the learning process, and is supported by educational strategies encouraging note-taking and attentive study habits.
Step-by-step explanation:
To develop her observant function by focusing on what's happening 'in the moment,' Nicki should engage in activities that require active and present-minded thinking. The best option for Nicki would be:
B. Focus on her current assignment and take notes.
Focusing on her current assignment and taking notes will require Nicki to concentrate on the material she is currently studying. This practice of observation is an excellent method to be present and fully engaged with the course content, thereby enhancing her ability to absorb information and notice fine details. Note-taking also aids in the analysis and understanding of the material, which is a vital component of learning effectively and is aligned with the advice of rereading textbooks and doing reflective tasks as suggested in the reference material.
Other options, such as taking the exam first (A), inviting friends over for a movie marathon (C), or looking ahead at future courses (D), might distract from the goal of being fully present and observant of the current academic task.
