She was shipwrecked off the western coast of Cornwall, England, on 18 March 1967, causing an environmental disaster. At that time she was the largest vessel ever to be wrecked.

1693. Which one of the following is not a primary pollutant?

by
A. Particulate matter
B. Carbon monoxide
C. Sulpuric acid

Ozone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source. Similarly, sulphuric acid is also not a primary pollutant.

1694. The percentage of water vapour present in the air compared to that required for saturation is the:

by
A. Mixing ratio
B. Absolute humidity
C. Dew point
D. Relative humidity
✅ The correct answer is option D.
Air with a 50 percent relative humidity actually contains one-half the amount of water vapor required for saturation. Air with a 100 percent relative humidity is said to be saturated because it is filled to capacity with water vapour.

1696. _________ energy is the main driving force of the ecological system.

by
A. Hydro
B. Solar
C. Electric
D. Mechanical
✅ The correct answer is option B.
The driving force for an ecosystem is solar energy. Plants use solar energy to synthesize their food by the process of photosynthesis. From solar energy, the energy is transferred to plants and other organisms via plants. Thus, the correct answer is ‘Solar energy’.

1697. The wind-chill factor:

by
A. Relates body heat loss with wind to an equivalent temperature with no wind
B. Indicates the temperature at which water freezes on exposed skin
C. Takes into account humidity and air temperature in expressing the current air temperature
D. Tells farmers when to protect crops from a freeze
✅ The correct answer is option A.
Wind-chill or windchill is the lowering of body temperature due to the passing-flow of lower-temperature air. Wind chill numbers are always lower than the air temperature for values where the formula is valid. When the apparent temperature is higher than the air temperature, the heat index is used instead.

1698. The Anthrax disease is caused by

by
A. Virus
B. Bacteria
C. Protozoa
D. Helminthes
✅ The correct answer is option B.
