Final answer:
Prereading activities include concept mapping, discussion, and questioning, and therefore, the correct answer is 4) all of these.
Step-by-step explanation:
Prereading activities are designed to prepare students for a deeper engagement with the text they will be reading. These activities can include concept mapping, which allows students to visualize the relationships between different concepts in the text. Discussion is another critical prereading activity, as it enables students to share their ideas and predictions about the text, fostering a collaborative learning environment.
Additionally, questioning strategies are part of effective prereading activities because they help to stimulate students' curiosity and encourage them to think critically about what they are about to read. Therefore, the correct answer to the question is 4) all of these, as all these strategies - concept mapping, discussion, and questioning - are included in prereading activities.
