1) The causes and physical characteristics of pandemics and disasters are very different. More than any previous
disaster such as Ebola, HIV, SARS, TB and malaria , the Coronavirus Disease (COVID‐19) has exposed underlying risks and
vulnerabilities and challenged the traditional notion of risk .The impact on population groups with pre‐existing vulnerabilities has
been particularly severe especially where the health crisis has turned into a humanitarian and economic crisis. There are
examples of countries.

In the Asia‐Pacific region that experienced disasters in the year or months before the onset of the COVID‐19
pandemic and where the impacts of both the virus itself and the government response to contain its spread have
either reinforced the socio‐economic impacts of the previous disaster or have impeded planned recovery efforts. In
April 2020, the small island states of Fiji, Solomon Islands, Tonga and Vanuatu were impacted by Tropical Cyclone
Harold. While they were relatively isolated from the health risks of COVID‐19 due to early closure of borders,
they were already feeling the effects of economic losses due to reduced market demand from tourism, fisheries and
global commodities

[Option ID = 45445]

Topic:‐ MCA C

1) Air pollution is the single greatest environmental risk to living beings and one of the main causes of death and disease
globally. Air pollution affects all but it disproportionately affects women, children and the elderly, especially in low‐income
populations as they are often exposed to high levels of ambient air pollution and indoor air pollution from cooking and heating
with wood fuel and kerosene and also has a negative impact on ecosystems.

Some air pollutants, such as black carbon, methane, hydro‐ fluorocarbons and ground‐level ozone, are also short‐lived climate
pollutants and are responsible for a significant portion of air pollution‐related deaths, as well as impacts on crops and hence food
security, so their reduction has co‐benefits for the climate. The average atmospheric lifetime of a single black carbon soot
particle is only two or three weeks. Methane has an atmospheric lifetime of 12 years. Ground‐level ozone lasts only a few hours
to a few days in the atmosphere. The average HFC lifespan, weighted by their respective emissions, is 15 years.

All countries need to substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil
pollution and contamination by 2030, as well as to reduce the adverse per capita environmental impact of cities, including by

paying special attention to air quality and municipal and other waste management by 2030.

Today, the international community acknowledges that improving air quality can enhance climate change mitigation and that
climate change mitigation efforts can improve air quality. Seventh of September every year is designated as the International
Day of Clean Air for blue skies.

5) Air pollution is the single greatest environmental risk to living beings and one of the main causes of death and disease
globally. Air pollution affects all but it disproportionately affects women, children and the elderly, especially in low‐income
populations as they are often exposed to high levels of ambient air pollution and indoor air pollution from cooking and heating
with wood fuel and kerosene and also has a negative impact on ecosystems.

Some air pollutants, such as black carbon, methane, hydro‐ fluorocarbons and ground‐level ozone, are also short‐lived climate
pollutants and are responsible for a significant portion of air pollution‐related deaths, as well as impacts on crops and hence food
security, so their reduction has co‐benefits for the climate. The average atmospheric lifetime of a single black carbon soot
particle is only two or three weeks. Methane has an atmospheric lifetime of 12 years. Ground‐level ozone lasts only a few hours
to a few days in the atmosphere. The average HFC lifespan, weighted by their respective emissions, is 15 years.

All countries need to substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil
pollution and contamination by 2030, as well as to reduce the adverse per capita environmental impact of cities, including by
paying special attention to air quality and municipal and other waste management by 2030.

Today, the international community acknowledges that improving air quality can enhance climate change mitigation and that
climate change mitigation efforts can improve air quality. Seventh of September every year is designated as the International
Day of Clean Air for blue skies.

1) What is the floating point representation of 12.25?[Question ID = 11373]
1. 1100.01 [Option ID = 45489]
2. 1100.11001 [Option ID = 45490]
3. 1100.10 [Option ID = 45491]
4. 1100.10011 [Option ID = 45492]

2) Consider the following function:
void swap (int x, int y)
{
int temp = x;
x = y;
y = temp;
}
The above function is invoked as follows:
int a = 3;
int b = 4;
swap(a, b);
What will be the values assigned to a and b on execution of the function call:
swap(a, b)?

[Question ID = 11374]
1. a = 3, b = 3

[Option ID = 45493]
2. a = 3, b = 4

[Option ID = 45494]
3. a = 4, b = 3

[Option ID = 45495]
4. a = 4, b = 4

[Option ID = 45496]
