Q:

Statement I :

By far the most common topographic form in a Karst terrain is the sinkhole.

Statement II :

Topographically, a sinkhole is a depression that varies in depth from less than a meter to few hundred meters.

A) Both the statements are individually true and Statement II is the correct explanation of Statement I B) Both the statements are individually true but Statement II is not the correct explanation of Statement I
C) Statement I is true but Statement II is false D) Statement I is false but Statement II is true
 
Answer & Explanation Answer: B) Both the statements are individually true but Statement II is not the correct explanation of Statement I

Explanation:

A sinkhole (in Karst topography) is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water.

Formation of a Sinkhole: In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone. These cracks are called joints. Slowly, as the limestone dissolves and is carried away, the joints widen until the ground above them becomes unstable and collapses. The collapse often happens very suddenly and without very much warning. Water collects in these collapsed sections, forming sinkholes.

Sinkholes also form when the roofs of caves collapse. Sinkholes are often funnel-shaped, with the wide end open at the surface and the narrow end at the bottom of the pool.Sinkholes vary from shallow holes about 1 meter (3 feet) deep, to pits more than 50 meters (165 feet) deep.

1.Alluvial soils are rich in nitrogen content.

2.Black soils are rich in iron and lime but deficient in nitrogen.

3.Laterite soils are rich in iron and aluminium but deficient in nitrogen and potassium.

 

Select the correct answer using the code given below.

A) 1 and 2 only B) 3 only
C) 2 and 3 only D) 1, 2 and 3
 
Answer & Explanation Answer: C) 2 and 3 only

Explanation:

Alluvial Soils

The proportion of nitrogen is generally low, but potash, phosphoric acid and alkalis are adequate, while iron oxide and lime vary within a wide range.

Black Soils

Chemically, the black soils are rich in lime, iron, magnesia and alumina. They also contain potash. But they lack in phosphorus, nitrogen and organic matter.

Laterite Soils

With rain, lime and silica are leached away, and soils rich in iron oxide and aluminium compound are left behind.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

 


Doing an internship at the University of Lille in France, I almost always found myself stuck whenever I had to speak to non-Indians about India or on anything 'Indian'. This was more because of the subtle differences in the way the French understood India in comparison to what I thought was 'Indian'. For instance, when I, or any Indian for that matter, say 'Hindi' is an Indian language, what it means is that it is one of the languages widely spoken in India. This need not be similar to the understanding that the French would have when they hear of 'Hindi' as an Indian language. Because for them Hindi then becomes the only language spoken in India. This is a natural inference that the French, Germans, Italians and many other European nationals would tend to make, because that is generally how it is in their own respective countries. The risk of such inappropriate generalisations made about 'Indian' is not restricted to language alone but also for India's landscape, cuisine, movies, music, climate, economic development and even political ideologies. The magnitude of diversity of one European country can be easily compared to that of one of the Indian State, isn't it? Can they imagine that India is one country whose diversity can be equated to that of the entire European continent? The onus is upon us to go ahead and clarify the nuances in 'Indianness' while we converse. But why should one do so? How does it even matter to clarify?

 

Why do some French people think that Hindi is the only Indian language?

 

A) Because that is the way in most European countries B) That is what is being taught to them
C) They know India is also called as Hindustan so people there must speak only Hindi D) As most Indians they meet speak Hindi
 
Answer & Explanation Answer: A) Because that is the way in most European countries
