Assertion (A): Relative stability of the system reduces due to the presence of transportation lag. Reason (R): Transportation lag can be conveniently handled by Bode plot.
In the following question, one statement is given, followed by two conclusions I and II. You have to consider the statements to be true, even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any follow from the given statement. Statement: People generally prefer driving their own vehicles over public transportation to go for work which leads to increase in pollution. People should use public transportation or atleast use carpooling if they care to bring down pollution levels.  Conclusion I: Using Public transportation or carpooling will bring down the rising pollution levels.  Conclusion II: People who use personal vehicles instead of public transportation are rich. 
The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: The government is working on a plan to set up a waterway freight corridor to connect the mainland with the northeastern states via Bangladesh at a cost of Rs 5,000 crore. The move would substantially reduce the time taken to transport goods to the eight northeastern states and costs.  Which of the following support the idea that the time of transportation will be reduced between the eight northeastern states? Arguments: I.The proposed 900-km waterway would be used to transport freight from the northern and eastern states to the northeast and would start near Haldia in West Bengal, go to the Sundarbans, merge into the Padma river in Bangladesh and then join up with the Brahmaputra in Assam.  II. Currently, highway connectivity to the northeastern states is patchy and transportation of goods by road entails a high cost and takes time. According to the ministry’s estimate, the waterway could help reduce the cost of transportation by about 70%.  III. The government is already developing a waterway along the Ganga river between Haldia and Allahabad (1,620 km) at a cost of Rs 4,500 crore. This link will also be utilised for trade between India and Bangladesh.
Negative exponential term in the equation of the transfer function causes the transportation lag.
In the question below is given a statement followed by two courses of action numbered I and II. You have to assume everything in the statement to be true and on the basis of the information given in the statement, decide which of the suggested course of action logically follow(s) for pursuing. Statement: The excessive utilization of fossil fuels for energy and transportation causes serious environmental problems. Courses of Action: I: People should increase the consumption of petrol and diesel. II: People should start using alternative sources of energy and transportation.
The network formed by resistors and capacitors for modifying the rate of change of gain and the phase shift is called a compensating network. Which of the following statements are not correct ? (A) The main purpose of a compensating network is to modify the performance of op-amp ciruit over the desired frequency range (B) There are two types of op-amps : internally compensated and externally compensated (C) 741 C is an externally compensated op-amp while 709 C is internally compensated op-amp (D) The phase lag and phase lead are most commonly used compensating networks in op-amps (E) Phase lag contributes a positive phase angle and phase lead a negative phase angle Choose the most appropriate answer from the options given below :
