Question

Consider the following statements and select the option which correctly identifies true (T) and false (F) ones.
(i) Rainfall is measured with the help of hygrometer.
(ii) Thick layer of subcutaneous fat, thick skin and a dense feather cover in penguins protect them from severe cold weather.
(iii) Polar bears have large ears that help them in the conservation of heat.
(iv) As we move higher up from sea level temperature becomes lower.

• A. (i): F; (ii): F; (iii): T; (iv): F
• B. (i): F; (ii): F; (iii): T; (iv): T
• C. (i): T; (ii): T; (iii): F; (iv): T
• D. (i): F; (ii): T; (iii): F; (iv): T

Answer 1

The correct option is D (i): F; (ii): T; (iii): F; (iv): T

• The first statement is wrong. Rainfall is measured by rain gauge.
• The second statement is correct as thick layer of fat beneath the skin protects them from severe cold weather.
• The third statement is incorrect as polar bears have small ears for conservation of heat.
• The fourth statement is correct because as we move upward from sea-level, the temperature of air decreases.
