Choose the option that is NOT true according to the text.

b) The house sparrow is the state bird of Delhi
c) Sparrows are often found perching on mobile towers
d) Sparrows are now visible only in some pockets in the country

Answer 1

SPARROWS – HERE TODAY, GONE TOMORROW?

• Option C) Sparrows are often found perching on mobile towers is NOT true.

• Supportive sentences from the text: Sparrows are known to be sedentary birds that usually do not prefer undertaking long flights. However, with the advent of mobile telephony and the corresponding erėction of mobile towers any and everywhere has made the sparrows an unwitting prey to technology. Mobile towers are known to emit radiation in the frequency of 900 to 1800 MHz which not only harms the thin chick skull and sparrow eggs, but also confuses and disorients the sparrow’s navigational skills. Sparrows are rarely, or rather never found in areas having mobile towers.

Answer 2

c) Sparrows are often found perching on mobile towers is NOT true according to the text.

Explanation:

• Sparrows are social birds and are very closely associated with the habitation of humans. The rapid changing cities are making difficult for the birds to survive.
• They usually build nest on the roofs of the houses. The modern infrastructure of the building are not accommodating the nests of the birds.
• The change in the city structure and infrastructure majorly depends on the population levels. Thus, rise in population is also a cause of reduction in sparrows.
• The microwaves from the towers affect the brain of the birds and they drop dead instantly.
• The pesticides in the plants and water made the survival of the sparrow difficult.
