Answer: b

Explanation:

A study by Toxics Link, a Delhi-based research and advocacy group, has found high levels of lead contamination in soil near battery recycling units across Delhi-NCR.  

• It is a naturally occurring element found in small amounts in the earth’s crust.
• Properties
  • It is a soft, silvery white or grayish metalin Group 14 (IVa) of the periodic table.
  • Lead has a bright lustre and is a dense, ductile, very soft, highly malleable, bluish-white metal that has poor electrical conductivity.
  • It is also highly resistant to corrosion and because of this property is used to contain corrosive liquids (e.g. sulphuric acid).
• Occurrence: It is usually found in ore with zinc, silver and copper and is extracted together with these metals.
• The main lead mineral is galena (PbS). Other common varieties include cerussite (PbCO3) and angelsite (PbSO4).
• Uses of Lead:
  • The principal use of lead is for lead-acid batteries for vehicles, backup emergency systems, the telecoms sector and fork lift trucks.
  • Lead is also used in rolled and extruded products, compounds in the glass and plastics industries, shot and ammunition and for radiation shielding. 
• Impact on Human Health:
  • It is highly toxic to humans and the environment.
  • Exposure to lead can affect multiple body systems and is particularly harmful to young children and women of child-bearing age.
  • Lead is distributed to the brain, liver, kidney and bones. It is stored in the teeth and bones, where it can accumulate over time.

Hence only statements 1 and 3 are correct.

Answer: c

Explanation:

Recently, researchers reported that at an extreme speed, the cornstarch mixture behaves like a liquid first before becoming tougher. 

• It is substance produced through wet milling of corn(Zea mays).
  • Wet milling separates the components of corn kernels, which consist primarily of protein, fibre, starch, and oil.
  • Once separated, the starch is dried, forming a white powder called cornstarch.
• Cornstarch is high in carbohydrates but lacking in vitamins, protein, fibre, and minerals, making it one of the least nutritionally dense components of corn.
• Applications of Cornstarch:
  • It absorbs moisture, however, making it useful as a thickener and anticaking agent in food products.
  • It is used in certain oral medications, where it facilitates the disintegration of capsules and tablets.
  • It may be used as a substitute for wheat flourin gluten-free foods and as a substitute for baby powder.
  • It is used in food processing, papermaking, and the production of industrial adhesives; it is also a component of many cosmetics and oral pharmaceutical products.
  • It has been used as a lubricant in surgical gloves.

Hence both statements are correct.
