A recently released UNICEF report titled "Clear the Air for Children” states that some 300 million children are exposed to heavily toxic air, while two billion live in areas where pollution exceeds minimum air quality guidelines set by the World Health Organization. South Asia has the largest number of children living in such areas, around 620 million, followed by Africa and then East Asia and Pacific region. According to this report, among these children around 600,000 under the age of five die globally due to air pollution. Besides being a major factor contributing in the deaths of these children, air pollution also threatens the future of millions more every day. Pollutants don't only harm children's developing lungs but they can actually cross the blood-brain barrier and permanently damage their developing brains and, thus, their futures. While the air is poisoned by vehicle emissions, fossil fuels, dust, burning waste and other airborne pollutants, indoor air pollution, typically caused by burning coal and wood for cooking and heating also impair children's health. The UNICEF report urged all governments worldwide to adapt measures such as cutting back on fossil fuel combustion as well as investing in energy efficiency and renewable energy sources.

  • According to the UNICEF report, ----.

A
household air pollution cannot be ignored as it endangers mortality rates in children
B
few children around the world are at risk and live in minimum air quality
C
almost 620 million children die each year because of being subjected to extremely toxic air
D
air pollutants cause temporary but severe deterioration of children's brain cells while damaging their lungs
E
vehicle emissions, fossil fuels and other toxic gasses might restrain air pollution worldwide

The Department of Justice has issued official guidelines for the manufacture of smart guns - weapons that have technology to allow only the owners to use them. Ordered by President Obama, the guidelines aim to “shape the future of gun safety technology”. In order to prevent thousands of deaths from misuse of guns, guns could be equipped with technology, such as fingerprint scanners, enabling only the owner to use them. However, although Obama’s initiative is undoubtedly with good intention, institutions like The National Rifle Association – which had previously boycotted Smith & Wesson’s pledge to explore smart gun technology – have sneered that Obama’s aim is to claim a win before his days in office end. Likewise, the Congress had also refused to fight the gun deaths among the nation. The technology is available. A shotgun that blocked firing by anyone without the shooter’s radio-frequency identity ring was already developed in 2000. Yet, what is not available is emancipation from the politics and threats of the gun lobby who, apparently, do not want to lose their share of the market that is more lucrative without the standards that the guidelines mean to bring.

  •  According to the passage, the guidelines for the production of smart guns ----.

A
are welcomed by the gun lobby for they bear the potential to create new income channels
B
are rejoiced by the entire country in that they will start a new era of gun safety technology
C
have been proposed upon the Congress’s call for a way of dealing with gun-related deaths
D
do not seem to be very promising since the required technology is still at its infancy
E
are meant to set the standards for gun production with aim to decrease deaths by gun misuse
