Which one of the following crops is generally benefitted by the rain caused by western disturbances in India ?

Rice
Wheat
Bajra
Cotton
This question was previously asked in
UPSC NDA-2 – 2023
Western Disturbances are extra-tropical storms that originate in the Mediterranean region and bring sudden winter rain and snow to the northwestern parts of the Indian subcontinent. This precipitation, though sometimes associated with hailstorms or cold waves, is beneficial for the Rabi crops (winter crops) grown in Northern India. Wheat is the most important Rabi crop, and the winter rainfall brought by Western Disturbances is crucial for its successful cultivation, especially in states like Punjab, Haryana, and Uttar Pradesh.
– Western Disturbances bring precipitation during the winter season in North India.
– This winter precipitation is essential for Rabi crops.
– Wheat is a major Rabi crop that benefits significantly from this rainfall.
Rice is a Kharif crop (summer crop) and is not grown during the winter when Western Disturbances are active. Bajra (pearl millet) and Cotton are also predominantly Kharif crops, although some varieties or regions might have different cycles.

24. Which one of the following climatic regions of the world have a typica

Which one of the following climatic regions of the world have a typical characteristic of seasonal reversal of wind ?

British type Climate
Mediterranean Climate
China type Climate
Monsoon Climate
This question was previously asked in
UPSC NDA-2 – 2023
Seasonal reversal of wind is a hallmark characteristic of the Monsoon climate. This phenomenon is caused by the differential heating of land and sea, leading to significant seasonal shifts in atmospheric pressure and wind patterns. During the summer monsoon, winds blow from the sea to the land, bringing heavy rainfall. During the winter monsoon, winds blow from the land to the sea, resulting in dry conditions in many regions.
– Monsoon climate is characterized by distinct wet and dry seasons.
– This seasonality is driven by large-scale seasonal changes in wind direction (reversal).
– This contrasts with other climate types like Mediterranean (dry summers, wet winters with Westerlies) or British type (uniform precipitation, dominated by Westerlies).
The term ‘monsoon’ is derived from the Arabic word ‘mausim’, meaning season. Major monsoon regions include South Asia, Southeast Asia, and parts of Australia and Africa.

The North-South Corridor connects Srinagar in the north to Kanyakumari in the south. The East-West Corridor connects Silchar in the east to Porbandar in the west. These two corridors intersect at the city of Jhansi, located in the state of Uttar Pradesh.
– The North-South Corridor runs from Srinagar to Kanyakumari.
– The East-West Corridor runs from Silchar to Porbandar.
– The intersection point of these two corridors is Jhansi.
The NHDP is a project aimed at upgrading, augmenting, and rehabilitating major National Highways in India. The Golden Quadrilateral, connecting the four major metropolitan cities (Delhi, Mumbai, Chennai, Kolkata), is another significant part of this project.

26. Which one of the following is an organic soil ?

Which one of the following is an organic soil ?

Aridisols
Histosols
Oxisols
Vertisols
This question was previously asked in
UPSC NDA-2 – 2023
Organic soils are characterized by their high content of organic matter, typically formed from the accumulation and decomposition of plant remains. In the USDA soil taxonomy system, Histosols are an order of soils that are primarily composed of organic materials (often >20-30% organic carbon by weight) in the upper 80 cm, commonly found in wetland environments like bogs, marshes, and swamps.
Histosols are defined by their high organic matter content, distinguishing them from mineral soils.
Aridisols are soils of arid and semi-arid climates, typically low in organic matter. Oxisols are highly weathered soils found in tropical and subtropical regions, rich in iron and aluminum oxides. Vertisols are clay-rich soils that shrink and swell significantly with changes in moisture content. These other soil orders are classified as mineral soils.

27. Which one of the following is NOT an example of Fold Mountain ?

Which one of the following is NOT an example of Fold Mountain ?

Mt. Fuji
Alps
Andes
Rockies
This question was previously asked in
UPSC NDA-2 – 2023
Fold mountains are formed when tectonic forces compress layers of rock, causing them to buckle and fold. The Alps in Europe, the Andes in South America, and the Rockies in North America are all major mountain ranges formed by folding. Mount Fuji, located in Japan, is not a fold mountain; it is a stratovolcano (composite volcano), formed by successive layers of volcanic ash and lava.
Mountains are formed through various geological processes, including folding, faulting, and volcanism. Fold mountains are a result of crustal compression.
Other types of mountains include fault-block mountains (formed by faulting and uplift), volcanic mountains (formed by volcanic activity), and dome mountains (formed by upward pushing magma). Mt. Fuji is an active volcano and a prominent example of a volcanic mountain.

28. Arrange the following in correct chronological order 1. Charak Samhit

Arrange the following in correct chronological order

1. Charak Samhita

2. Bharat’s Natyashastra

3. Sangam Literature

4. Ashtadhyayi

Select the correct answer using the code given below :

1 - 3 - 4 - 2
2 - 4 - 1 - 3
4 - 3 - 1 - 2
3 - 1 - 2 - 4
This question was previously asked in
UPSC NDA-2 – 2023
Arranging the texts in chronological order based on approximate standard datings:
4. Ashtadhyayi by Panini: Generally dated to the 4th century BCE.
3. Sangam Literature: Spans roughly from 3rd century BCE to 3rd century CE, with some earlier roots. The core period (Ettuthogai and Pattupattu) is often placed from 1st century BCE to 2nd century CE.
2. Bharat’s Natyashastra: Dates vary, but often placed between 2nd century BCE and 2nd century CE, frequently cited around the 1st century BCE or 1st century CE.
1. Charak Samhita: Classical text on Ayurveda, generally dated to the 1st-2nd century CE.

The most plausible chronological order, starting with the earliest, is Ashtadhyayi, followed by the beginning of Sangam Literature, then Charak Samhita and Natyashastra (which are roughly contemporary or Natyashastra slightly earlier, but often grouped together). Option C places them as 4-3-1-2, which corresponds to Ashtadhyayi -> Sangam -> Charak Samhita -> Natyashastra. While the relative order of Charaka and Natyashastra can be debated, this is the only option that correctly places the earliest text (Ashtadhyayi) first and the ancient literature (Sangam) before the classical texts (Charaka/Natyashastra).

The chronological order of ancient Indian texts is often based on scholarly dating approximations, which can sometimes vary slightly. Ashtadhyayi is one of the earliest known Sanskrit texts. Sangam literature represents an early period of Tamil literature. Charak Samhita and Natyashastra are foundational texts in Ayurveda and performing arts, respectively, belonging to the classical period.
Pinpointing exact dates for these ancient texts can be challenging due to limited historical evidence and ongoing scholarly debate. However, the relative order of Ashtadhyayi preceding Sangam (at least the start of the period), and both preceding Charak Samhita and Natyashastra is widely accepted. The option C sequence (4-3-1-2) fits this general progression, even if the specific placement of 1 before 2 might depend on the specific dating applied.

29. Which one of the following Ashokan Minor Rock Edicts, contains the per

Which one of the following Ashokan Minor Rock Edicts, contains the personal name of the king – Ashoka ?

Maski
Bahapur
Bairat
Sahasram
This question was previously asked in
UPSC NDA-2 – 2023
Most Ashokan edicts refer to the king as “Devanampiya Piyadasi” (Beloved of the Gods, of Pleasing Appearance). His personal name “Ashoka” is found in only a few of the Minor Rock Edicts. Among the options provided, the Maski Minor Rock Edict is famous for being one of the edicts where Ashoka is referred to by his personal name, “Asoka”. Other edicts containing the name “Asoka” include Gurjara, Nettur, and Udegolam.
The Maski edict is significant because it helped confirm the identification of “Devanampiya Piyadasi” mentioned in numerous other edicts with Emperor Ashoka.
The Bairat (or Bhabru) edict is known for Ashoka’s declaration of faith in the Buddha, Dhamma, and Sangha. Bahapur is the location of an Ashokan inscription in Delhi. Sahasram (Sasaram) is also a location of a Minor Rock Edict, but it refers to the king as “Devanampiya”.
