Question Discussion & Solution

The correct answer is 60%.

Key Points

• Rajasthan is India's only state that has a real hot desert within its territory.
  • Vast stretches of sand dunes of different kinds - longitudinal dunes, barchans, transverse dunes - are characterized by physiography.
  • Almost 60% area of the THAR Desert in India falls in Rajasthan.

Additional Information

• In reality, a portion of the Thar Desert extending into Pakistan is the Great Indian Desert, covering the districts of Barmer, Jaisalmer, Jalor, Jodhpur, Bikaner, Ganganagar, Churu, Jhunjhunun, Sikar, Nagaur, and Pali.
• The total area of the arid tract is 233,100 square kilometres or approximately three-fifths of the Rajasthan State.
• The rock exposures in the Thar region are predominantly of Aravali gneiss and schist, Malani granites, and Vindhyans, indicating that Thar is part of the peninsular block's western extension.
• Jurassic and Eocene marine formations belong to the rock exposures in the Barmer - Jaisalmer - Bikaner tract to the extreme west and north, whereas those in the central area of Jalor - Siwana - Jodhpur - Khinwasar tract are of igneous rocks, often overlaid by Vindhyan sedimentaries.
• There is also proof of a great culture that had flourished in the past there.
• The deep-seated formations, such as the Jaisalmer Lathis, are small potable water zones with local recharge facilities.
• The blown sand superimposes large stretches of alluvium contributed by ancient rivers in their submerged channels.
• Recurring aridity has endowed this tract with items such as gypsum, potash, common salt, at different stages of geological times. Phosphorus, and bentonitic and ceramic clays.

Important Points

•  The question has been cancelled

Humans eat both vegies and meat so are omnivore, whereas Cats which eats meat only so its carnivore.

The correct answer is Femur.

• It is the largest, longest, and strongest bone in the human body.
• The femur runs from the keen to the hip.
• The Femur or thigh bone is the largest and heaviest bone in the human body.
• At the proximal end of the Femur, there is a rounded prominence which is called the Head of the Femur.
• The femur runs from the keen to the hip.
• It carries all the upper body weight.
• The other parts of the leg are the tibia, femur, fibula, and keep cap also known as patella.

Additional Information

• The human skeleton is made up of 206 bones, including bones of the
  • Skull:  including the jaw bone (mandible, maxilla)
  • Spine: cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx)
  • Chest: ribs and breastbone (sternum)
  • Arms: the shoulder blade (scapula), collar bone (clavicle), radius, humerus and ulna
  • Hands: wrist bones (carpals), metacarpals and phalanges
  • Pelvis: hip bones
  • Legs: the thigh bone (femur), the kneecap (patella), shin bone (tibia) and fibula
  • Feet: tarsals, metatarsals, and phalanges.

The correct answer is caffeine.

Caffeine is the main active constituent of tea and coffee.
Additional Information

• Caffeine works by stimulating the central nervous system (CNS), heart, muscles, and the centres that control blood pressure.
  • Caffeine can raise blood pressure, but might not have this effect on people who use it all the time.
  • Caffeine can also act like a “water pill” that increases urine flow.
• Nicotine works by stimulating our nervous system to release specific chemical messengers (hormones and neurotransmitters) that affect different parts of our brain and body.
  • One hormone that nicotine affects is epinephrine, also known as adrenaline.
• Chlorophyll is a green pigment found in plants.
  • Plants use chlorophyll and light to make food.
  • People sometimes use chlorophyll as medicine.
  • Common sources of chlorophyll used for medicine include alfalfa, algae, and silkworm droppings.

After reading statements and conclusion we decide that -

i) Some basketball players are not women. → False (We do not have any information about the other basketball player they can be women or men)

ii) Not all basketball players are women.→ False (This is a possibility but we cannot say definitely)

Hence, option 4 is the correct answer.
