Soil is one of the most important natural resources as mankind is dependent on soil for food. The soils of Rajasthan have developed under the arid and humid climate over the bedrocks of complex nature predominately through the process of Lateralization.

Classification: The old system of classification was developed by scientists (Thorpe & Smith) of the U.S Department of Agriculture in 1949. The classification is based upon differences in climate and mineralogy. As per this system, soils of Rajasthan can be classified into 8 types:

1. Desert Soils
2. Dunes and Associated Soils
3. Brown Soils
4. Sierozems
5. Red Loams
6. Hill Soils (Lithosols)
7. Saline Sodic Soils (Solonchaks)
8. Alluvial Soils/and Black Soils

Brown soil:

• Brown Soils Major area of these soils is in the catchment area of Banas River.
• Districts – Tonk, Bundi, Sawai Madhopur, Bhilwara, Udaipur, and Chittorgarh
• Annual Rainfall – 50 cm to 75 cm is sufficient for Kharif crops.
• Texture – Sandy loam to clay loam.
• Colour – Ranges from greyish brown to yellow-brown.
• They are rich in calcium salts but have poor organic matter
• The use of fertilizers becomes essential to get a good harvest
• As the groundwaters are saline, soils irrigate with these waters have accumulated salts
• Tank irrigated soils have also developed a problem of the high water table.
• Rabi crops are grown under irrigation.

Hence, option 1 is the correct answer.

The correct answer is the 15th Bengal Native Infantry.

• The battalion that rebelled at Nasirabad in 1857 was the 15th Bengal Native Infantry.
  • The first rebellion in Rajasthan took place on 28 May 1857 at Naseerabad
  • News of Meerut Rebellion AGG (Agent to Governor-General) George Patrick Lawrence and he sent the 15th Bengal Native Infantry based at Ajmer to Nasirabad, causing discontent among the soldiers.
  • Soon the news of the revolt of the soldiers reached the soldiers in Nasirabad as well and on 28 May 1857, the soldiers of the Native Infantry revolted in Nasirabad.
  • The soldiers of the 30th Native Infantry also joined in and after burning and capturing the soldiers of the cantonment left for Delhi.

LAN :

• LAN stands for Local Area Network.
• It's a group of computers which belong to the same organisation, and are linked within a small geographic area using a network using the same technology (Ethernet).
• E.g. Wi-Fi

MAN :

• MANs (Metropolitan Area Networks) connect multiple geographically nearby LANs to one another at high speeds.
• A MAN lets two remote nodes communicate as if they were part of the same local area network.
• E.g. microwave antenna on a TV news van, extended high in the air, beaming video and sound back to the main TV studio.

WAN:

• A WAN (Wide Area Network or extended network) connects multiple LANs to one another over great geographic distances.
• WANs operate using routers, which can "choose" the most appropriate path for data to take to reach a network node.
• E.g.: Internet

PAN:

• A personal area network (PAN) is a network used for data transmission amongst devices such as computers, telephones, tablets, personal digital assistants, fax machines and printers, that are located close to a single user

E.g. Bluetooth

The correct answer is Liver.

Key Points

• Excessive consumption of alcoholic drinks causes damage to the Liver.
  • Alcohol is readily absorbed from the digestive tract, and up to 98% is metabolised in the liver.
  • Each liver cell contains three pathways for alcohol metabolism.
  • All of these result in the production of a highly toxic metabolite which can contribute to liver cell damage.
  • With regular alcohol use, the regenerative ability of liver cells may be inhibited and lead to sustained liver damage.
  • Long term heavy alcohol use may lead to fat accumulation in the liver, which may progress to alcoholic hepatitis, or liver cirrhosis.
  • Over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including -
    • High blood pressure, heart disease, stroke, liver disease, and digestive problems. 

Additional Information

• Kidney:
  • Healthy kidneys remove wastes and extra fluid from your blood.
  • But when your kidneys fail, wastes and extra fluid can build up in your blood and make you feel sick. 
  • Kidneys can become damaged from a physical injury or a disease like diabetes, high blood pressure, or other disorders.
  • High blood pressure and diabetes are the two most common causes of kidney failure.
  • Kidney failure does not happen overnight.
• Lungs:
  • Chronic alcohol abuse and heavy drinking can greatly increase the risk of several pulmonary conditions.
    • including lung disease, alcoholic pneumonia, acute lung injury, and acute respiratory distress syndrome.
  • Smokers are more likely than nonsmokers to develop heart disease, stroke, and lung cancer.
    • Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs.
    • Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis.
• Heart:
  • Smokers are at greater risk for diseases that affect the heart and blood vessels.
  • Increases in your blood pressure can also be caused by weight gain from excessive drinking.
  • Heavy drinking weakens the heart muscle, which means the heart can't pump blood as efficiently.
    • It's is known as cardiomyopathy and can cause death, usually through heart failure.
