Answer the following:

a) Advantages of PowerPoint + inserting video: Advantages: visual training (depot safety with photos), chart-based monthly review, public awareness, reusable handouts/PDF, remote sharing. Steps to insert video: select slide → Insert → Media → Video → This Device/Stock/Online → pick MP4 → set Playback (on click/automatically, trim, volume) → Compress Media if file heavy → F5 to test audibility from back row.

b) Tags and attributes in HTML: Tag = markup command in <> defining structure: <p>, <table>, <a>, <img>. Most pair (<h1>...</h1>); some empty (<br>, <img>). Attribute = extra info inside tag: href, src, width, bgcolor. Example: <a href="https://noc.org.np">NOC site</a> — a is tag, href is attribute giving destination. <img src="depot.jpg" width="300"> shows image 300px wide.
