Question Discussion & Solution

The correct answer is Zila Parishad → Panchayat Samiti → Village Panchayat.

Key Points

• Panchayati Raj
  • Panchayati Raj is the system of local self-government of villages in rural India as opposed to urban and suburban municipalities.
  • It consists of the Panchayati Raj Institutions (PRIs) through which the self-government of villages is realized.
  • They are tasked with "economic development, strengthening social justice and implementation of Central and State Government Schemes including those 29 subjects listed in the Eleventh Schedule."
  • ​Part IX of the Indian Constitution is the section of the Constitution relating to the Panchayats.
  • It stipulates that in states or Union Territories with more than two million inhabitants there are three levels of PRIs:
    • Zilla Parishad at the District Level
    • Panchayat Samiti at the Block Level
    • Gram/Village Panchayat at the Village Level

 Additional Information

• The Panchayat Raj system was first adopted by the state of Rajasthan in Nagaur district on 2 Oct 1959 but first started by Andhra Pradesh.
• During the 1950s and 60s, other state governments adopted this system as laws were passed to establish panchayats in various states.
• The modern Panchayati Raj system was introduced in India by the 73rd constitutional amendment in 1993.

The correct answer is Calcium carbonate.

Important Points

• Calcium carbonate and its forms:
  • In nature, calcium carbonate occurs in the forms of chalk, limestone, and marble.
  • Formation:
    • ​The skeletal remains of dead sea animals sink to the seabed. Over millions of years, layer build-up and pressure from the top layer changes the bottom layer into chalk. 
  • Earth movements due to earthquake lift the layer of chalk to the Earth's surface. 
  • The earth's movements can also cause the layers to sink further. Thus, high pressure and heat cause the chalk to turn into much harder limestone. 
  • The limestone deposit may stay below the Earth for a longer time and due to higher pressure and temperature, the limestone turns to marble.

The correct answer is Rice.

• Rice blast disease, caused by Magnaporthe oryzae (Ascomycota), occurs in about 80 countries on all continents where rice is grown, in both paddy fields and upland cultivation.
• The extent of damage caused depends on environmental factors, but worldwide it is one of the most devastating cereal diseases, resulting in losses of 10–30% of the global yield of rice.
• Other common diseases of the crop of rice are - Blight, Bacterial leaf streak, Brown spot, Sheath blight, False smut, etc.

Additional Information

• The biological agents that causing diseases to plants are known as pathogens. 
• Some of the viral diseases in plants are - bud blight (soyabeans), Curly tops (Beans, tomato, etc.), Mosaic leaf (Tomato, pea, potato,tobacco, etc.).
• Some of the bacterial diseases in plants are - Blights (vegetable crops), Bacterial wilts (Tobacco, potatoes, etc), Cankers (Woody plants), Leaf Spots, Soft Wrots, etc.
• Some of the fungal diseases in the plants are - Cankers, Ergot, Rusts, Root rots, Scabs, Smuts, etc.
   

The correct answer is "option 2"

CONCEPT:

Structure in C is a user-defined data type that is used to store the collection of different data types.

The total size of the structure is the sum of the size of every data member.

Union is a user-defined data type that is used to store different data types in the same memory location.

The total size of the union is the size of the largest data member.
 

EXPLANATION:

Given the size of short, float and long is 2 bytes, 4 bytes, and 8 bytes, respectively.

Therefore,

Size of Structure → size of ( short s[5] ) + size of Union  

Here, Size of Union = 8 bytes   { largest data member is long }.

Size of short s[5] → 2×5 → 10 bytes

Size of Structure → 10+8 →18 bytes.

Hence, the correct answer is "option 2".
