Intensive agriculture is the most typical method of soil cultivation and the key source of food worldwide. It relies on reaping high yields with strong and often extreme land exploitation and often extreme inputs. The main benefits of intensive farming include sufficient food supplies at affordable prices.
Three major characteristics of intensive farming are as follows,
Low fallow ratio Labour and capital intensive Higher crop yields per unit land area. It is important to mention here that in areas of intensive subsistence agriculture, animal husbandary is a meager sideline of crop farming.
Throughout the region the farmers are handicapped in raising cattle due to a lack of scientific methods of breeding the animals although it is one of the reason of sidelining of livestock but the main reasons may be:- Less availability production or low quality fodder available to animals because of high pressure on farmer to produce staple foods of land area, tow pasture So we can say that both statements are correct but R is not the correct explanation of A.

Friedrich Ratzel who was a German geographer and ethnographer, originated the concept of Lebensraum, or "living space," which relates human groups to the spatial units where they develop.
Ratzel produced the foundations of human geography in his two-volume Anthropogeographie in 1882 and 1891 other books are " History mankind"
• Application geography to history.
• The geographic distribution to mankind
This work was misinterpreted by many of his students. creating a number of environmental determinists.

Osmosis is the process which is related to absorption of inorganic salts and water by plant roots. It is the movement of a solvent, such as water, through a semi-permeable membrane. It contributes to the movement of water through plants.

The government of India provides IT resources to its employees to enhance their efficiency and productivity. These resources include desktop devices, portable and mobile devices, networks including wireless networks, Internet connectivity, external storage devices and peripherals like printers and scanners, and the software associated therewith. These resources are meant as tools to access and process information related to their areas of work. So A is correct. MNC's means multinational companies of India have outperformed in the total revenue and even in I.T. export market share. Notably, exports dominate the Indian IT industry and constitute about 79% of the industry's total revenue. However, the domestic market is also significant, with robust revenue growth.
So R is also correct but not the correct explanation of A.

R. Johnson is not associated with political Geography. He is associated with the study of coastal morphology, urban social geographical and electoral geography. He recognizes the concept of shoreline zones.

Developments of India's international trade can be broadly divided into three different phases under;
Pre- Independence Phase (1500 BC - 1947)
Post - Independence Phase (1947 - 1990)
Post Trade -Liberalization Phase. (from 1991)
It is very important to understand that from 1947-1991, the Indian economy remained largely as a closed economy. High taxes were levied on import of items. Foreign investments like FDI were restricted and during 1970's & 1990's mobility of factors of production remained in focus.
However, after the liberalization of economy in 1991, foreign trade improved significantly. Now, India exports around eight thousand commodities to about 195countries, and imports around 6000 commodities from 140 countries.
Exports and Imports are not only restricted to commodities (merchandise). Service is also a major export/import item.

Given data
Temperature = 20°C
Saturation mixing ratio, Us = 20 grams
Mixing ration, U = 5 grams
Calculation
Relative Humidity = U/Us
RH (%) = (5/20)*100 = 100/4 = 25
Therefore, the correct Relative Humidity (%) is 25%.
Relative humidity (RH)
It is a measure of how much water vapor is in a waterair mixture compared to the maximum amount possible. RH is a ratio of the humidity ratio of a particular waterair mixture compared to the saturation humidity ratio at a given temperature (dry-bulb). It is important to note that the relevance of relative humidity to a particular application depends on knowing both the dry-bulb temperature as well as the RH.
