Question 1: What is the impact of thread type on stitch strength in sewing machine operation, especially in high-stress areas?

Which action should you take?

Choose only one option

Different thread types (e.g., polyester, cotton) offer varying strength and flexibility, affecting durability

Thread type does not affect stitch strength, only appearance

Polyester thread is weaker and should only be used for decorative stitches

Cotton thread is weaker and should only be used for decorative stitching

Question 2: How does "thread tension" affect the quality and appearance of a stitch?

Which action should you take?

It guarantees faster stitching regardless of fabric type

A skilled operator can maintain high production speed while ensuring consistent quality

It ensures that all garments will fit perfectly

It reduces the need for machine adjustments

Question 6: What is the purpose of adjusting the presser foot pressure on a sewing machine?

Which action should you take?
