Read the following article and select the best answer. Article: At the age of 14, Hugh Evans spent a night with cockroaches crawling all over him. That experience turned out to be life-changing for Evans, now 30. Far removed from his comfortable home in Australia, he traveled to the Philippines with an aid organization that set him up with a host family. Their home was in Smokey Mountain, a teeming slum in Manila. A boy in the family, Sonny Boy, was the same age as Evans. The difference between their lives shocked him hard. "I believed that I wanted to commit my life to this," said Evans. "I want to see an end to extreme poverty in my lifetime." It's the same goal shared by global organizations and world leaders, and some great progress has been made in reducing the number of the world's poorest. In 1981, about half the developing world lived in extreme poverty. By 2010, it had fallen to about 20 percent. The organization has set 2030 as the goal to reduce the rate even further, to 3 percent. The gains worldwide are unbalanced. China and Southeast Asia have made huge progress in lifting their populations above that line. But the opposite is true in some areas in Africa. Even though economic growth is developing across the continent, the number of extremely poor people actually increased over the last three decades. The organization's campaign, "Live Below the Line", hoped for an even greater effect by actually having people eat the way that the world's poorest have to do every day. This year about 15,000 people worldwide joined in the campaign such as Ben Affleck and Josh Groban, as well as other notables, such as Jill Biden and Hunter Biden, the vice president's son. The campaign will raise up to $4,000,000 for various aid organizations working to help the world's poorest. Question: The author mentioned Evans' experience in his teens to _ . - help us know him well - warn us not to live a poor life - show how he missed his teenage time - show how the poor life experienced in the Philippines influenced him
show how the poor life experienced in the Philippines influenced him

Question: Read the following article and select the best answer. Article: British Summer Time runs from the last Sunday in March to the last Sunday in October. In the depths of winter the nights in the UK are anything from 15-19 hours long. Longer nights mean frost and fog are more likely to form. Twice a year the clocks change, forward in the spring and then back again in the autumn. But why? It happens twice a year. We all change our clocks and watches by one hour. In the spring, we add an hour, and go onto what is called British Summer Time, while in the autumn, we do the reverse, and return to Greenwich Mean Time. Why bother? It's all to do with saving the hours of daylight, and was started by a guy called William Willett, a London builder, who lived in Petts Wood in Kent. Basically, he figured that you could improve the population's health and happiness by putting forward the clocks by twenty minutes every Sunday in April and do the opposite in September. Economics His idea was not taken up, even though a "Daylight Saving Bill" was introduced some five years before the outbreak of World War One. But once the war started, it was considered wise to economics, to promote greater efficiency in using daylight hours, and in the use of artificial lighting. And so in 1916, "Daylight Saving Time" was introduced. Even though most countries abandoned this after that war, some eventually decided that it was a good idea, and most of these nations began to keep it throughout the year. Experiment Since 1972, Britain has decided to go with Greenwich Mean Time in winter, and British Summer Time in Summer. But back in 1968, Britain tried a four-year experiment by advancing time one hour ahead of GMT throughout the year. But those living further north, particularly in Scotland, found it most unsatisfactory, with dark mornings for much of the year, and the experiment was dropped. Question: Why some countries decide to change the clocks after World War One? - To improve the people's health and happiness. - To do a certain experiment - To save energy to develop economies. - All of the above.
Answer:
To save energy to develop economies.
