Analyzing Extension Education Aids

The question asks to identify the 2-D Aids used in extension education activities.

Let's analyze each option:

• Flash cards: These are flat cards displaying information visually. They are two-dimensional (2-D).
• Flip charts: These consist of large pages bound together, flipped over manually to present information sequentially. They are two-dimensional (2-D).
• Posters: These are large visual graphics printed on paper or similar material, designed to convey information quickly. They are two-dimensional (2-D).
• Campaigns: These are planned series of activities or events designed to achieve a specific outcome. While they use various aids, a campaign itself is a process, not a 2-D aid.
• Radio: This is an audio medium used for broadcasting information. It is a one-dimensional (audio) aid, not a 2-D visual aid.

Identifying Correct 2-D Aids

Based on the analysis, flash cards (a), flip charts (b), and posters (c) are distinct 2-D aids commonly employed in extension education.

Campaigns (d) are strategies, and radio (e) is an audio medium.

Therefore, the correct combination includes (a), (b), and (c).

This corresponds to Option 1.
