"I could see this gray, dome-shaped body in the distance, like a giant whale swimming near the surface. Hundreds of people had gathered to watch it in disbelief." This island has become a global curiosity. How was it formed in just a few minutes? As you might already know, many islands in the sea are formed by volcanoes. There are numerous volcanoes under the sea. As the hot lava erupts and cools down, it piles up and forms the shape of a mountain. When the mountain "grows" to higher than the sea level, the part that's above the water is what we call an "island". This is how the island was formed after the Pakistan earthquake, except that instead of a regular volcano, it was a "mud volcano" that brought about this island. Lava is not the only thing that's locked under the Earth's crust -- there is also gas. When an earthquake happens and breaks part of the crust, the gas is released at an extremely high speed, pushing mud up to the surface, according to National Geographic. But only earthquakes that are extremely powerful can cause mud volcanoes to push up enough mud to produce islands -- and this 7.7-magnitude earthquake in Pakistan was strong enough. The island is about 20 meters high, up to about 90 meters wide and 30 meters long, nearly the size of a soccer field. In fact, mud volcano islands aren't new. This is the fourth island of this kind in the region since 1945. But those islands usually didn't last long. "It will probably be gone within a couple of months," said Bill Barnhart, a researcher with the US Geological Survey. After all, "it's just a big pile of mud that was on the seafloor that got pushed up". Question: What is the article mainly about? Options: A: The disastrous effects of coastal earthquakes. B: The difference between mud volcanoes and regular volcanoes. C: How islands are formed by mud volcanoes. D: The great natural wonders of Pakistan.

Article: Ask a group of elderly people what it was about their lives that made them happiest overall, and they'll probably mention some warm relationships with family and friends. If you're satisfied with your social life, according to psychologists, you tend to be satisfied with life in general. From the point of my 50s, I'd say that sounds about right. Some of my happiest moments are the ones I spend with my husband, a few close relatives, and a handful of very good friends who know me well and like me anyway. But the more I read about how social media are interfering with good old-fashioned friendship, creating virtual bonds that can't quite take the place of real ones, the more I wonder just how today's 20-somethings will look back on their own lives when they're my age. After all, much crucial relationship building work is done in the 20s. According to research by the late Bernice Neugarten of the University of Chicago, who helped launch the academic study of human development, people choose most of their adult relationships, both friends and lovers, between the ages of 22 and 28. The friends we make in our 20s are not only best friends forever; they're also our first truly chosen friends. And choosing how to commit to these friendships is an essential psychological task of the 20s. But with so much of friendship in this age group now being developed online, an essential question is what the effect of that interaction is. A study, conducted in 2010 by Craig Watkins and Erin Lee of the University of Texas at Austin, investigated the Facebook habits of 776 young people between the ages of 18 and 35. "Whether it is a wall post, a comment, or a photo," they wrote, "young people's engagement with Facebook is driven, primarily, by a desire to stay connected to and involved in the lives of friends who live close by, far away, or have just entered into their lives." This kind of constant contact can be efficient, but it can also be upsetting. For one thing, it adds a new layer of concern to a young person's... Question: The author may agree that _ . Options: A: old-fashioned friendship can help create virtual bonds B: there's no need for young people to make online friends C: real-world friendship is a better choice for young people D: online friendship is an inevitable trend in the modern world
