The social media website has earned a reputation for reconnecting old friends. Last week, a guy whom I hadn't seen since my bachelor party five years ago sent me a friend request. I accepted and waited for "Easy E" to send me a greeting of some kind. He had sought me out, after all. I learned from his profile that he was in a relationship and had a son. However, I'm pretty sure we won't ever write wall-to-wall, let alone e-mail each other. But he'll remain a friend of online until one of us makes a point of removing the other from his official list. My pool of friends consists of family members, college buddies, co-workers from past and present, and friends of friends. There are 35 in all. If I spent some time uploading old e-mail addresses, I'm confident that I could increase my friend count actually. A person could make a mission out of reconnecting with childhood friends, former classmates, distant cousins, and those one would like to get to know better. And some people can even handle hundreds of on-screen relationships, keeping up with the daily happenings of their small army of companions. After all, there are worse fates than having too many friends. Thanks to e-mail, the inability to schedule face-to-face meetings no longer means a friendship must come to a close. But even with e-mail, people will lose touch if one or both parties stop writing back. That's normal. People move from school to school, job to job, city to city. You never have to feel guilty for breaking away. Every day, the masterminds of Web 2.0 find new ways of making human communication easier. _ . Some things shouldn't be simplified. When it comes to friendship, there can be no shortcuts.

To solve the problem, we should have to double our food production. We can also develop a diet of algae , insects and meat grown in laboratories. Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars. Man-made meat looks like meat, feels like meat and it is meat, although it's never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land. China has developed "green super rice", a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years. Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein , low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes.

input: Please answer the following: Write a multi-choice question for the following article: Article: I fell in love with the minister's son the winter I turned fourteen. He was not Chinese. For Christmas I prayed for the boy, Robert. When I found out that my parents had invited the minister's family over for Christmas Eve dinner, I cried in panic. What would Robert think of our shabby Chinese Christmas? What would he think of our noisy Chinese relatives who lacked proper American manners? On Christmas Eve, my mother created abundant Chinese food. And then they arrived--the minister's family and all my relatives. Robert greeted hello, and I pretended he was not worthy of existence. Dinner threw me deeper into disappointment. My relatives licked the ends of their chopsticks and reached across the table. Robert and his family waited patiently for a large plate to be passed to them. My relatives murmured with pleasure when my mother brought out the whole steamed fish. Robert made a face. Then my father reached his chopsticks just below the fish eye and picked out the soft meat. "Amy, your favorite," he said, offering me the tender fish cheek. I wanted to disappear. At the end of the meal, my father leaned back and burped loudly, thanking my mother for her fine cooking. "It's a polite Chinese custom to show you are satisfied," explained my father to our astonished guests. Robert was looking down at his plate with a reddish face. The minister managed to bring up a quiet burp. I was shocked into silence for the rest of the night. After everyone had gone, my mother said to me, "You want to be the same as American girls on the outside." She handed me an early gift. It was a miniskirt. "But inside you must always be Chinese. You must be proud that you are different. Your only shame is to have shame." It was not until years later that I was able to fully appreciate her lesson and the purpose behind her particular menu. For Christmas Eve that year, she had chosen excellent Chinese food.
