High-flying ideas?

A camera-equipped drone flies around the outskirts of Seoul, South Korea, hovering near an industrial plant and capturing video of pollutants. Below, on the crowded, litter-covered streets, residents wear white and black masks that cover their noses and mouths. A gray haze hangs in the sky.

The unmanned aerial vehicle, or UAV, is part of a pilot program by South Korea’s Ministry of Environment. Tasked with inspecting factory emissions in the capital’s greater metropolitan area, it’s the latest in a series of tech solutions aimed at solving Seoul’s dust dilemma. In fact, the fine dust has South Koreans so concerned they’ve cited it as their No. 1 stressor in life – more distressing than the country’s economic stagnation, its rapidly aging population and even North Korea’s erratic dictator and nuclear weapons program.

Their worries are well-founded. The World Health Organization (WHO) advises exposure to fine dust, or PM10, of no more than a daily average of 50 micrograms per cubic meter, and to ultra-fine dust, or PM2.5, of no more than 25. At one point in 2017, Seoul’s PM10 hit 179. In late March 2018, Seoul’s PM2.5 soared to over 100. PM2.5 is of greatest concern. So small it can get lodged into the lungs and penetrate the lining to enter the bloodstream, PM2.5 is comprised of black carbon, nitrates, ammonia and other harmful compounds linked to respiratory diseases and cancer. The WHO has classified fine and ultra-fine dust as carcinogenic since 2013.

Developed by the government-run National Institute of Environmental Research, the drone is the first of what the environment ministry intends to be a fleet deployed nationwide. Some South Korean tech companies, too, are stepping inwith their own innovations. Although much of the new tech appears promising, Greenpeace’s Seoul office stresses the importance of addressing the root of the problem. Part of the solution is getting residents to recognize their own role in curbing carbon output. So, even though the new fixes may do a good job of measuring dust, what about actually busting it? That’s where the technology hasn’t quite caught up yet.

QUESTÃO 13

Albert Einstein 2019: According to the third paragraph, PM2.5 is currently a topic of greatest concern in Seoul because

(A) it has recently reached levels far beyond those the WHO admits as safe for humans to live with.

(B) its particles have just been discovered to be even tinier than the average PM10 particles.

(C) it has, in the latest years, surpassed PM10 in numbers and as the origin of incurable diseases.

(D) it is composed of black carbon, nitrates and ammonia, a combination inevitably resulting in deadly side-effects.

(E) it has been announced by the WHO as the main cause for respiratory diseases and cancer in the country.

QUESTÃO ANTERIOR:
- Albert Einstein 2019: The pilot program mentioned in the second paragraph uses UAVs primarily to

RESOLUÇÃO:
De acordo com o terceiro parágrafo, PM2.5 é atualmente um tópico de grande preocupação em Seoul porque recentemente atingiu níveis muito acima daqueles aceitos pela OMS como sendo considerados seguros para a vida dos humanos.

No texto:
“The World Health Organization (WHO) advises exposure to fine dust, or PM10, of no more than a daily average of 50 micrograms per cubic meter, and to ultra-fine dust, or PM2.5, of no more than 25. At one point in 2017, Seoul’s PM10 hit 179. In late March 2018, Seoul’s PM2.5 soared to over 100.”

GABARITO:
(A) it has recently reached levels far beyond those the WHO admits as safe for humans to live with.
