1. Question
Which of the following can be considered as the advantages of soil mulching?
1. It reduces soil salinity by reducing evaporation.
2. It modifies the microclimate of the soil and the air in which the plant grows.
3. It totally restricts reptile movement and rodent activities.
Select the correct answer using the code given below.CorrectAnswer: C
Reptile movement and rodent activities are experienced in some places as mulching
inadvertently facilitates an environment for increased activities of burrowing reptiles and
rodents. Hence statement 3 is not correct.IncorrectAnswer: C

4. Question
With reference to the characteristics of the ocean currents, consider the following statements:
1. The speed of the ocean currents decreases with depth.
2. The surface currents constitute the majority of all the water in the ocean.
Which of the statements given above is/are not correct?CorrectAnswer: B
Currents are referred to by their “drift”. Usually, the currents are strongest near the surface and
may attain speeds over five knots. At depths, currents are generally slow with speeds less than 0.5
knots. Hence statement 1 is correct.Deep water currents make up the other 90 per cent of the ocean water. These waters move around
the ocean basins due to variations in density and gravity. Deep waters sink into the deep ocean basins
at high latitudes, where the temperatures are cold enough to cause the density to increase. Hence
statement 2 is not correct.IncorrectAnswer: B
