Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?
Examine the following statements about span of control and identify the ones which are true?
1. More task complexity requires narrower span of control.
2. Routine tasks can have greater span of control than exceptional tasks.
3. When tasks are dissimilar, then span of control can be larger.
4. Spans of control are generally narrower at the top and broader at the bottom of the hierarchy.
is no need of revision of control limits once calculated by the equations of control limits.

In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: Delhi Metro commuters may face tough time as Metro's 9,000-strong workforce of non-executive employees have threatened to go on a strike from June 30. The non-executive workforce including train operators, station controllers, technicians, operations staff, maintenance staff, have been protesting since June 19 at various depots and control rooms of the Delhi Metro for revision of salaries and right to form Union. Last year too, Metro services had come to the brink of a shutdown when the non-executive staff had threatened to go on strike on similar demands. Assumptions: I. The employees demand pay hike, payment of arrears, right to form a union and fixed guidelines for sacking an employee only in extreme conditions.  II. There is no consistency maintained during upgradation of scales and employees are stuck in one grade since a long period. III. There would be no maintenance of trains and trains will not be rolled out of train depots. Station controllers would ensure that entry to metro stations is also closed for public.
