Projection technology can support classroom communication when it makes relevant material visible and easier to discuss.
Assertion: Using a projector may help a teacher communicate diagrams, images, or examples to a large class.
Reason: It can cover extensive content, but covering more material does not automatically make communication effective.
Question-quality note: The marked A treats the reason as the correct explanation. Visibility, clarity, interaction, and students’ understanding would provide a stronger explanation than the quantity of content covered. This assertion–reason item should be reviewed before its key is treated as certain.
