Final answer:
The professor used a written comprehension test which may have included multiple-choice or open-response questions to gauge the students' understanding of the reading material.
Step-by-step explanation:
Johanna's professor utilized a written comprehension test to assess the students' understanding of the material. This type of test often includes reading a passage and responding to questions based on the content, which can range from simple recall to more complex critical thinking questions. Assessments in written comprehension may feature multiple-choice questions, short-response items, or even open-response formats that require more in-depth analysis.
While multiple-choice questions at the end of a chapter are common and provide opportunities to apply knowledge, it is also important to recognize the value of questions that encourage deeper engagement with the text. Instructors might use a test bank with a range of question types to customize assessments in alignment with course objectives. The goal is to encourage flexibility in thinking and confirm core conceptual understanding, beyond just looking for a single correct answer.
