How to lay out the answer. Follow the frame, then write it in your own words.
1 · Open in two lines. Ring and rotor spinning are the two main conventional methods that turn fibre strands into yarn. Ring uses roving and a traveller; rotor uses sliver and a rotor.
2 · Draw the ring frame. [Sketch: roving bobbin → drafting rollers → guide → traveller on ring → bobbin on spindle]
3 · Ring spinning.
Roving drafted by three pairs of rollers.
Traveller on ring and spindle insert twist.
Ring rail builds the bobbin; yarn rewound into cones.
4 · Draw the rotor unit. [Sketch: sliver → opening roller → air duct → rotor groove → yarn drawn out through the centre → package]
5 · Rotor spinning.
Sliver opened into single fibres.
Air carries fibres into the rotor.
Yarn end twists fibres in and is wound on a large package.
6 · Compare.
Feed: roving vs sliver.
Speed: slower vs several times faster.
Yarn: stronger, finer, smoother vs weaker, coarser, bulkier.
Uses: shirting, thread vs denim, towels.
7 · Daily-life link. Ring or compact yarn for soft babywear and hospital gowns; rotor yarn for absorbent, low-cost towels.
8 · Close in one line. Ring spinning gives quality and range; rotor spinning gives speed and low cost.
Scoring tip: A side-by-side table of at least six points is the core of this answer; the two sketches add easy marks.
