Concept:
The indirect yarn count system is based on a "hank" (a standard length of yarn). The count is defined as the number of hanks required to weigh one pound. Each fiber type has its own standardized length for a single hank.
Step 1: Identifying standard lengths:
• Cotton (A): In the English cotton count system, the standard length for one hank is 840 yards (III).
• Linen (B): In the linen system, the "lea" or standard hank length is 300 yards (I).
• Jute (C): For jute and some heavy wools, a larger unit called a "spyndle" is often used, which measures 14400 yards (IV).
• Wool (D): While worsted wool uses 560 yards, the woolen run system corresponds to 256 yards (II) as identified in the provided list.
Step 2: Conclusion:
Matching the values results in the sequence A-III, B-I, C-IV, and D-II, identifying option (3) as correct.
