Read the following article and select the best answer. Article: Barack Obama makes his first trip to Asia as president this week, leaving behind a host of domestic problems with the visit that recognizes the region's economic and diplomatic importance. "Obama"s trip includes stops in Japan, Singapore, China and South Korea, and his message will be simple, says Nicolas Lardy at the Peterson Institute for International Economics. "Well, I think his broadest aim is to convince Asians that the United States is fully committed to the region that we have an agenda that's much broader than they saw over the past eight years of the very heavy focus on anti-terrorism." Obama's first stop is Japan, where he meets with the new Prime Minister Yukio Hatoyama who has promised to steer a diplomatic course more independent of Washington. While Japan is seen as a getting-to-know-you stop, when Obama heads to the Singapore for the APEC meeting, he will likely face pressure on trade. "Many Asians are concerned about what US trade policy will be, and they've been somewhat alarmed by the fact that the president really hasn't set out very much revision for what US trade policy is in his administration." But the critical _ of the trip will come in China, his third stop where Obama will have to navigate the complex relationship with the country that is the largest holder of US debt. "As you say, you know, if you owe the bank one dollar, it's your problem, if you owe the bank, you know, 3 million dollars, it's the bank's problem, so it's similar with China. I mean they have no interest in trying to use the influence with us, because eventually, they're the one that they own all those dollars." Also on the table will be North Korea and Iran's nuclear ambitions as well as cooperation on Afghanistan. With Obama enjoying sky high popularity level in the countries he is visiting, detailed results may be beside the point, given that Obama is still in his first year in office, analysts say this trip is mostly about laying the ground work for the future. Question: The author develops the passage mainly _ . - by examples - by cause and effect - by comparison - by order in time

Read the following article and select the best answer. Article: Men weigh up potential partners almost instantaneously based on their appearance because their "ancient" genetic preference for attractive mates leads them to, experts claim. According to research, a woman with an attractive face is taken by men to be fertile and able to continue the family line, appealing to the man's survival instinct. In contrast women take longer to decide their feelings for a man because they need to weigh up whether he will be a committed partner who will provide for them well - part of their survival programming. They tested men and women's preference towards looks by conducting a series of tests on 20 women and 20 men, making them perform tasks while recording their brain activity. While the subjects were doing the task they were shown a series of photographs of faces of the opposite sex, ranging from attractive to ugly. Men were easily distracted when they saw a pretty face but women stuck to the task. Prof van Vugt said: "Men definitely have the most wandering eye but it is because they have evolved to pay attention to cues of fertility and one of those cues is facial beauty - it's not that men are shallow." But we found they do make snap judgments about women, much earlier than was previously thought. They make that decision on whether a woman would be a good mating partner in milliseconds. This is something very ancient and a way of helping men find the best mate to produce children. Women were not distracted by attractive male faces because women need more proof of whether a man is a good mate. "Women make that decision on behaviour, whether a man is trustworthy and committed. They make their decision much later than men." Question: The main idea of the passage is_. - that men love beauty because of gene - helping men find the best mate to produce children - testing men and women's preference towards looks - that mem were easily distracted when they saw a pretty face
(Answer)
that men love beauty because of gene
