• D. All

Answer 1

Answer:

B. i, ii

• (i) There are two kinds of shift system: This is correct. Typewriters typically use either a Single Shift (common in older/standard machines) or a Double Shift (seen in some portables or specialized machines). In a single shift system, the machine has one set of shift keys to access capital letters; in a double shift, the segment or platen can move to two different positions to access three different characters on a single type bar.

• (ii) Touch method is the scientific method: This is correct. The "Touch Method" involves typing without looking at the keys, using all eight fingers and the thumb on the "home row." It is considered scientific because it maximizes speed and accuracy while minimizing fatigue and mental strain.

• (iii) Carriage rack travels on escapement: This is incorrect. The Carriage Rack travels on the Pinion Wheel. While the Pinion Wheel is connected to the Escapement Wheel, the rack itself rests and moves across the pinion, not directly on the escapement mechanism.
