1. Average molecular orientation can be measured by :
        a. X-ray diffraction                       b. Infrared spectra
        c. Scanning electron microscopy             d. Birefringence
2. During length measurement on Fibrograph,2.5% span length was found
 to be 25 mm. It means
        a. 2.5% of fibres clamped are 25 mm is length
        b. 2.5% of fibres clamped are longer than 25 mm
        c. 2.5% of fibres clamped are 25 mm or longer
        d. 2.5% of fibres clamped are less than 25 mm
3. The count of a yarn is 20 Tex. It is equivalent to a yarn of
        a. 29.5 Ne (English count)              b.180 Denier
        c. 50 Nm(Metric count)                  d. None of the above
4. The resultant count of a two folt cotton yarn is 16s Ne. If the doubling process
causes a contraction of 10% in the component yarns, the count of the component
single yarn will be
