In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: An induction motor can, therefore, be made without electrical connections to the rotor. B: Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. C: An induction motor's rotor can be either wound type or squirrel-cage type. D: An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

P, Q, R, Sand T are five crops that Babu grows. T is fast growing and more water demanding than R which gives more yield than T. P gives more yield than R and grows faster than Q. Q is more water demanding than T but is second lowest yielder, S is the slowest growing and least water demanding of all crops but gives highest yield. R is more water demanding and grows faster than P. Select the crop or crops that has/ have as many as crops that are more water demanding and as many as crops that give less yield than it.

Examine the following statements relating to induction and identify those which are either true or false.
1. Induction today is renamed as empolyee orientation programme.
2. It is also known by the term 'on boarding'.
3. It is for the purpose of socialising the new employees.
4. Informal induction is better than formal induction.
Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
With reference to the properties of magnetism, consider the following statements: 1. A natural magnet is an oxide of iron. 2.

Similar poles repel each other and dissimilar poles attract each other. Which of the statements given above is/are correct?
