Question

Match List-I with List-II:

List-I (Machine parts)	List-II (Purpose)
(A) Feed dog	(I) Holds the bobbin
(B) Thread take up lever	(II) Pushes the fabric ahead
(C) Presser foot	(III) Feeds the thread to the needle
(D) Oscillating hook	(IV) Keeps the fabric pressed

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

The "feed dog" is named because it "feeds" (advances) the fabric forward, and the "presser foot" keeps the fabric "pressed" down.
Matching these two allows you to solve the question easily.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
A sewing machine contains several precision mechanical components working together to form a lockstitch by feeding the fabric, managing the thread, and securing the loops.

Step 2: Detailed Explanation:
Let us match the sewing machine parts to their mechanical functions:
1. Feed dog (A): A set of metal teeth that rises through the needle plate to grip and advance (push) the fabric forward by one stitch length. Thus, (A) matches (II) Pushes the fabric ahead.
2. Thread take-up lever (B): A moving metal lever that pulls thread from the spool and feeds it down to the needle, then pulls up the slack to tighten each stitch. Thus, (B) matches (III) Feeds the thread to the needle.
3. Presser foot (C): A metal foot that clamps down to hold the fabric flat and firm against the needle plate and feed dog during sewing. Thus, (C) matches (IV) Keeps the fabric pressed.
4. Oscillating hook (D): A hook component in the lower assembly that catches the needle thread loop and passes it around the bobbin case containing the bobbin. Thus, (D) matches (I) Holds the bobbin.
This gives the combination: (A) - (II), (B) - (III), (C) - (IV), (D) - (I).

Step 3: Final Answer
The correct option is (B).
