Question Discussion & Solution

The correct answer is Western disturbances.

Key Points

• Western Disturbances are responsible for the rainfall during winter over the northwestern part of India.
• The Western Disturbance originates in the mid-latitude region near Europe and the Atlantic Ocean.
  • The low pressure builds up over the Mediterranean Sea and moves over Iraq, Afghanistan, and Pakistan before entering India, and contains substantial amounts of moisture.
  • When these low-pressure systems reach the Indian subcontinent, they are blocked by the Himalayas and rain as snow over the northwestern plains and the higher reaches of the western Himalayas.
  • After precipitation over northwest India, they weaken and are devoid of moisture, they blow as dry winds that form dense fog over the northern plains of India.

Additional Information

• The period June to September is referred to as the Southwest Monsoon period.
  • Southwest Monsoon period is the principal rainy season for the Indian subcontinent.
  • This is the summer monsoon period where the southwest monsoon holds away over the country.
  • The whole country receives nearly 75% of its rainfall during this period.

The correct answer is about 70% water.

Important Points

• The Top Four Elements Found in the Human Body: oxygen (65%), carbon (18.5%), hydrogen (9.5%), nitrogen (3.2%).
• The other trace elements (less than 0.01%) are boron (B), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), silicon (Si), tin (Sn), vanadium (V), and zinc (Zn).
• The six major nutrients are carbohydrates (CHO), lipids (fats), proteins, vitamins, minerals, water.
• The functions of water in the human body:
  • Water carries nutrients and oxygen to all cells in the body.
  • Water is required for breathing.
  • Water regulates your body temperature.
  • Water protects and cushions vital organs.
  • Water cushions joints.
  • Water removes waste.

Key Points

• Calcium (Ca) is the most abundant mineral in the body and is essential for a number of vital functions.
  • Also helps muscles relax and contract, important in nerve functioning, blood clotting, blood pressure regulation, immune system health.
• Iron (Fe), Part of a molecule (haemoglobin) found in red blood cells that carries oxygen in the body, needed for energy metabolism.
• Iodine found in thyroid hormone, which helps regulate growth, development, and metabolism.
• Chromium works closely with insulin to regulate blood sugar (glucose) levels.

The correct answer is Brahmi.​

• The Edicts of Ashoka are in total 33 inscriptions written on the Pillars, boulders, and cave walls of the Mauryan Period, during the reign of the Emperor Ashok that are dispersed throughout the Indian Sub-continent covering India, Pakistan, and Nepal.
  • Inscriptions found in the eastern parts of the Mauryan empire are written using the Brahmi script in Magadhi language.
  • While in the western parts of the empire, the script used is Kharoshti, written in Prakrit. To add to the variety, one extract in the Edict 13 is written in Greek and Aramaic.
• A notable thing in these inscriptions is, that Ashoka refers to himself in many of these inscriptions as “Devampiyaa” which means “Beloved of the Gods” and “King Piyadassi.”
• The world came to know of these details of the Mauryan empire and Ashoka when the edicts and inscriptions were decoded by British Archaeologist James Princep. 

Key Points

• These edicts have mentioned that Buddhism as a religion had reached as far as the Mediterranean under the Ashokan reign.
• Many Buddhist monuments had been created in the wide-spread area.
• In these edicts, Buddhism and the Buddha are also mentioned.
• But primarily these edicts focus more on social and moral precepts rather than the religious practices (or the philosophical dimension) of Buddhism during Ashoka’s reign.

Explanation:

Trend in metallic property:

• As we move along a period from left to right, the metallic character decreases. The elements which are at the extreme left of the periodic table are most metallic in nature and the elements at the right side of the periodic table are non-metals in nature.
• As we go down the group, the metallic character increases and the non-metallic character decreases.
• So, metals at the extreme left and bottom of the periodic table are most metallic in nature.

Reactivity:

• As the metallic character increases, the Ionisation potential decreases and the reactivity of the elements also increases.
• The most reactive metal is thus Cs (Cesium), situated at the bottom left corner of the periodic table.

​

Hence, the most active metal known is Cesium.

• Francium is the element present at the bottom of the periodic table, but it is a lab-made element, and not naturally occurring, which makes Cs as the most reactive element. 

In this question shows that Cauliflower is vegetable but remaining Guava, Pomegranate and Mango are fruit. 

Hence, "Cauliflower" is the correct answer.
