The idea came to Nathan Eagle, a research scientist with the Massachusetts Institute of Technology, when he was doing a teaching stint in rural Kenya. He realised that, as three-quarters of the 4.6 billion mobile-phone users worldwide live in developing countries, a useful piece of technology is now being placed in the hands of a large number of people who might be keen to use their devices to make some money.① To help them do so, he came up with a service called txteagle which distributes small jobs via text messaging in return for small payments. Only 18% of people in the developing world have access to the Internet, but more than 50% owned a mobile-phone handset at the end of 2009 ( a number which has more than doubled since 2005 ), according to the International Telecommunication Union. One study shows that adding ten mobile phones per 100 people in a typical developing country boosts growth in GDP per person by 0.8 percentage points. Mr. Eagle hopes txteagle will do its bit by mobile "crowdsourcing"—breaking down jobs into small tasks and sending them to lots of individuals. These jobs often involve local knowledge and range from things like checking what street signs say in rural Sudan for a satellite-navigation service to translating words into a Kenyan dialect for companies trying to spread their marketing. ② A woman living in rural Brazil or India may have limited access to work, adds Mr. Eagle, "but she can still use her mobile phone to collect local price and product data or even complete market-research surveys. " Payments are transferred to a user’s phone by a mobile money service, such as the M-PESA system run by Safaricom in Africa, or by providing additional calling credit. Working with over 220 mobile operators, txteagle is able to reach 2 billion subscribers in 80 countries. It already has the largest contract-labour force in Kenya and new ways of using it are being found all the time. Recently a large media firm asked Mr. Eagle for help in monitoring its television commercials across Africa. The company was concerned that, although it had paid for broadcasting rights, its ads could be replaced with others by local television companies. So txteagle pays locals to watch and then text notes about which ads are shown. "I would never think of that myself," says Mr. Eagle. Which is why he is not sure just how big all these small text jobs could become. The one who is most likely to use txteagle is ______.

Questions 1 to 3 are based on the following conversation. At the end of the conversation, you will be given 15 seconds to answer the questions. Now, listen to the conversation. What will the woman have to do in a few months according to the conversation
[1] "Daddy, you’re crying," say my sons. "No, boys, I’m man-crying. Very useful skill. " [2] A short walk from my house in Hampshire, on a hill overlooking the heathland, is a plaque marking the spot where Richard Pryce Jones deliberately crashed his Halifax bomber during the war.① He could have parachuted to safety, but that would have meant crashing into the village. The epitaph reads: "He died that others might live. " [3] It never fails to move me. Not to tears, you understand. That would be disrespectful. But I do usually manage a lump in the throat and that film of moisture over the eyes that men have in their emotional armoury.② Gordon Brown demonstrated the non-crying cry beautifully when he made his farewell speech on the steps of Number 10. That catch in the throat. The determination not to weep in public. At that moment, if at no other, he had nobility. [4] Not everyone can carry it off. I don’t think Paul Gascoigne ever quite got the hang of it, for example. But I like to think I have it down to an art. My technique honed from years of watching The Railway Children, Sleepless in Seattle and that scene in Dumbo when the mother elephant is locked away. "Daddy!" my sons will say, pointing the accusing finger. "You’re crying !" [5] "Me Over Dumbo Ha ha ha. No, boys, what I am doing is man-crying, a sort of non-crying cry. I’ll teach you it one day. Very useful. " [6] They are too young to appreciate the nuance yet, but when they are older I will explain that open sobbing is associated with being female, and so inappropriate for men. ③The Charlie Chaplin analogy might be useful here. He once said that the way to act drunk is to imagine yourself a drunk man trying to act sober. The same is true when a man learns the non-crying cry. To be convincing, you must look as if you are trying to avoid tears. [7] Men have to be careful what they cry at, because some subjects are more worthy of tears than others. Grief, obviously. But not self-pity. And rarely should a man cry in pain. And never at the death of a princess he didn’t know. Those are the rules. [8] I suspect my colleague Matt Pritchett might be with me on this. One of his cartoons showed a father next to a television tuned to the World Cup, explaining to his children that "at some point in the next few weeks, you are going to see me cry". ④ And the day after the last survivor of the Great Escape died, he did a cartoon showing a gravestone with a mound of tunnelled earth trailing away from it. I seemed to have something in my eye when I saw that, and I expect he had the same something in his eye when he drew it. The word "nuance" in Paragraph 6 probably means______.
