Multiple choice

Directions: In the following question, four statements are provided between an opening statement 1 and a closing statement 6. The statements are jumbled up and form a coherent paragraph when properly arranged. Select the alternative representing the proper and logical sequencing of these six taken together.

  1. Machines can be divided into four groups: mechanical, electrical, fluid power, and prime movers.

A. Common examples of prime movers include waterwheels, windmills and nuclear energy plants.

B. They also convert energy in moving fluids to mechanical energy, as fluid motors, hydraulic cylinders, and turbines.

C. Prime movers convert natural forms of energy, such as those found in streams and winds, into mechanical energy.

D. Fluid-power machines convert mechanical energy to energy in moving fluids, as in compressors and hydraulic pumps.

  1. Similarly, electric machines convert mechanical to electrical energy as in generators and alternators and convert electrical to mechanical energy in electrical motors and loudspeakers.

  1. BDAC

  2. CADB

  3. BACD

  4. CBDA

B Correct answer
Explanation

As one can easily infer that sentence C describes the conversion of various forms of energy by prime movers, therefore, as in sentence A, example of prime movers has been given, it follows sentence C. In sentence 6, an analogy of electric machines converting two different forms of energy have been given. This therefore, needs some example preceding it. Therefore, DB should precede sentence 6. This sequence is presented in option (2), hence the answer.
