1Which tool is most suitable for measuring the circumference of a client's waist?
A.Flexible tailor's tape
B.Rigid L-square
C.French curve
D.Seam gauge with a short rigid rule
Explanation: A flexible tape follows the body's contours without requiring a flat surface. Hold it level and comfortably against the body without stretching it or compressing the measurement.
2Which lockstitch-machine part supplies slack needle thread during stitch formation and then rises to tighten the stitch?
A.Feed dog
B.Presser foot
C.Thread take-up lever
D.Bobbin winder
Explanation: The take-up lever moves in time with the stitch-forming mechanism. Its downward movement supplies thread, and its upward movement draws up the thread to tighten the formed stitch.
3A machine skips stitches on an elastic knit after sewing a stable woven successfully. Which initial action is most appropriate?
A.Increase the thread tension to its maximum
B.Pull the knit harder behind the foot
C.Use the same needle until it breaks
D.Check that a fresh needle of the machine-compatible type and size is suitable for the knit, then test on a scrap
Explanation: Needle selection and condition can affect loop formation and skipped stitches on knits. A suitable stretch or ballpoint needle may help, but threading, fabric control, and machine condition must also be checked if the fault persists.
4What is the purpose of a correctly fitted needle finger guard on a power sewing machine?
A.To control bobbin tension
B.To set the stitch length
C.To wind the bobbin while sewing
D.To reduce the risk of fingers entering the moving needle's path
Explanation: The guard helps keep fingers clear of the needle area during sewing. It complements safe handling and isolation before adjustments; it does not make it safe to reach into moving parts.
5Which fiber is obtained from the seed hairs of the cotton plant?
A.Wool
B.Silk
C.Cotton
D.Nylon
Explanation: Cotton is a natural cellulosic seed fiber. Its pressing and laundering treatment should still account for the garment's finishes, dyes, blends, and care instructions.
6In a supervised fiber-identification exercise using a tiny sample and appropriate fire and ventilation precautions, which observation most strongly suggests wool rather than cotton?
A.A paper-like burning odor with light ash
B.A hair-like burning odor and a dark, crushable residue
C.A smooth hard bead characteristic of a melting thermoplastic
D.A printed care label without any fiber information
Explanation: Wool's protein composition produces a characteristic hair-like odor and brittle dark residue when burned. Such observations are only preliminary evidence, especially for blended or finished fabrics; formal identification may need other methods.
7In a conventional woven fabric, where does the true bias run?
A.At 45° to the warp and weft
B.Along the selvage
C.At 90° to the selvage along the weft
D.Only along a finished hem
Explanation: True bias runs diagonally at 45° to the two perpendicular yarn directions. This orientation allows the yarn grid to deform more readily, giving bias strips useful flexibility around curves.
8Which weave is identified by diagonal surface lines, as commonly seen in denim?
A.Plain weave
B.Twill weave
C.Satin weave
D.Basket weave
Explanation: Twill interlacings progress across successive yarns to produce diagonal lines. The direction and prominence of those lines depend on the particular twill construction.
9For a fitted garment made from a stable woven fabric, what distinguishes wearing ease from design ease?
A.Wearing ease allows movement; design ease adds fullness for the intended style
B.Wearing ease is the seam allowance; design ease is the hem allowance
C.Wearing ease is added only at the hem; design ease only at the neckline
D.They both mean shrinking the pattern below body size
Explanation: Wearing ease provides room needed for movement and comfort. Design ease adds the volume needed for the chosen silhouette; neither has one universal allowance for every body, fabric, or garment.
10What is the main purpose of a basic block or sloper in pattern drafting?
A.To record only the cutting instructions for one decorative style
B.To provide a fitted foundation from which style patterns can be developed
C.To replace the need for body measurements
D.To grade fabric by fiber quality
Explanation: A basic block provides a foundation representing a defined size or figure with the intended basic fit. Style lines and other design features can then be developed from it, using the drafting system's allowance conventions.
