But these days, air pollution levels in the north eastern city of Harbin surpassed the previous record levels. The city was essentially shut down after PM2. 5, fine Particulate pollution that is considered hazardous . reached levels of 1000 micrograms per cubic meter-40 times the safety level remended by the World Health Organization. Schools, motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10 meters. Photos from Harbin showed residents covering their mouths with masks and scarves, and moving like ghostly shadows through the fog. Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible. . Just days previously , the World Health Organization's International Agency for Research on Cancer (IARC) classified air pollution as a carcinogen .

It's said that exposure has increased significantly particularly in " rapidly industrial countries with large populations". "The air we breathe has become polluted with a mixture of cancer-causing substances" , Dr Kurt Straif , head of the IARC said in a press released.

" On the Chinese social media site Weibo , many users complained about the pollution and shared their concerns. References to "feed people with smog "have become popular on Weibo and there is a sarcastic play on the expression "serve the people" , as the two have a similar pronunciation. "The impact of air pollution on people will be gradual. There won't be a sudden outbreak of symptoms, but normally three to five days after the smoggy weather occurs, there is a peak in the number of people seeing doctors, " Deng Ying, a doctor at the Second...

Ques: Read the following article and select the best answer. Article: A wood fire can be handy when you ' re camping. You can roast marshmallows or stay warm, for example. Forest fires that rage out of control, however, are a big problem. Wildfires cause hundreds of millions of dollars in damage every year. And the amount of destruction has grown over the last 2 decades,especially in the western United States. To understand better why the northern Rocky Mountains region has been hit especially hard by wildfires, scientists from the University of Arizona in Tucson looked at weather, snow, and fire records from 1970 to 2003. Their study showed that, between 1987 and 2003, fires burned an area 6. 5 times larger than the area burned between 1970 and 1986. The fire season also started earlier-, and its average length increased by 78 days. Warmer spring and summer temperatures appear to be part of the explanation for this change. The average temperature in the study's more recent period was 0.871 higher than it was in the earlier period. And this trend is likely to continue. Experts predict that average summer temperatures may rise between 23/4 and 53/4 by the year 2050 in western North America. Hie timing of snowmelt appears to be another cause of the fire boom. When snow melts early in the season,forests become drier through the summer and catch fire and burn more easily. Western snow packs now typically melt a week to a month earlier than they did 50 years ago, according to recent studies. Some people have blamed the growing fire risk on policies that allow bush and branches to build up on forest floors. But clearing bush by itself won' t help much if changes in climate are largely responsible for increasingly severe forest fires. Question: The main purpose of studying the records from 1970 to 2003 was to _ . - find out solutions to forest fires - prevent wildfires from happening frequently - - know more about the climate changes in the past decades - find out the causes of wildfires in the northern Rocky Mountains region
Ans: find out the causes of wildfires in the northern Rocky Mountains region

Question: Read the following article and select the best answer. Article: Men have long been puzzled by the amount women pack, when they go on holiday. They despair when they watch their beloved spend much money on extra baggage charge. Nearly half of these women admitted to lying about the weight of their case to their partner before leaving for the airport, in fear of being made to unload some unnecessary items. But it's a fact that women pack more than they need. On average, a woman needs around 57 items in suitcase for a two-week holiday, yet most women pack nearer to 150 items, ranging from skirts, tops, underwear and high heels. In addition, women pack more sun cream, make-up and hair appliances than they were likely to need. They all take up space in the suitcase, only a third of them will see the light of day once at the holiday place. 79 percent of women admitted to taking extra items with them, with the reason for this being "just in case". Women plan their holiday wardrobe months in advance. Packing enough clothes and other items to last a month is not enough for some women. They'd take a chance to shop for new items while holidaying abroad. So they'll return with even more luggage in their cases. Professor Karen Pine said: "Women are tempted to take familiar items with them on holiday, often everything except the kitchen sink. Some people find traveling stressful, particularly when they're unsure about the home comforts available at their holiday place. They over-pack to help cope with those feelings of stress and reduce the uncertainty." This will come as no surprise to some men, who are used to trying to squeeze their partner's luggage into the boot of the car with their own, smaller case. On the other hand, men pack very lightly, with only an average of 40 items for a two-week holiday. Question: Women pack too much on holiday because _ . - they want to show off their items - they prefer a more comfortable holiday - they are afraid they'll need them during the holiday - they would like to clean their clothes wardrobe very much
Answer:
they are afraid they'll need them during the holiday
