Question 2

The Bharathapuzha, often referred to as 'Nila', is Kerala's second-longest river and holds immense cultural significance. However, it faces severe ecological challenges, particularly a drastic reduction in water flow during the dry season. Which of the following human-induced factors is most directly responsible for exacerbating the dry season water scarcity and the associated increase in sand mining pressures in the river?

Accepted Answer

C. Excessive and unregulated sand mining from the riverbed, leading to deepening, loss of groundwater recharge, and lowering of the water table. — Excessive and unregulated sand mining is directly responsible for exacerbating dry season water scarcity in the Bharathapuzha. The removal of sand deepens the riverbed, detaching it from the surrounding water table, thereby reducing groundwater recharge and lowering the water table. This makes the river appear dry even when there is subsurface flow. While check dams (A) and deforestation (D) contribute to overall water stress, and pollution (B) affects water quality, sand mining directly impacts the river's physical structure and its ability to retain water during lean periods, making it the m

Answer

A. Construction of numerous check dams and barrages for irrigation in its upper reaches across both Kerala and Tamil Nadu.

Answer

B. Uncontrolled discharge of industrial and domestic waste into the river, leading to severe pollution.

Answer

D. Significant deforestation in the catchment area, reducing the capacity for water retention and percolation.

Question 9

Adequate ventilation in indoor spaces is crucial for preventing the spread of respiratory infections. Which of the following is the primary mechanism by which good ventilation helps reduce transmission?

Accepted Answer

B. It dilutes airborne pathogens, reducing their concentration in the air. — Good ventilation primarily helps prevent the spread of respiratory infections by diluting airborne pathogens. By introducing fresh air and removing stale air, it reduces the concentration of infectious particles in indoor environments, thereby lowering the risk of inhalation by occupants. While some filters can remove particles, and temperature/humidity can affect pathogen survival, dilution is the main principle of ventilation for infection control.

Answer

A. It increases the humidity, making the air less conducive for pathogen survival.

Answer

C. It filters out all airborne particles, including viruses and bacteria.

Answer

D. It raises the ambient temperature, deactivating heat-sensitive microbes.
